How Often Should You Calibrate Your Toxic/Flammable Gas Detector?

Toxic Gas Detector

Reprinted with permission from the United Electric Controls Blog.

When we think of gas detector calibration and how often it must be performed, it is dependent on many variables. First and foremost is determining if a gas sensor is out of calibration.

The best way to establish this is through a “bump” or functional test using a certified standard gas mixture of known concentration. If the device is functioning properly and still measuring gas within tolerance, calibration is unnecessary. Bump testing should be performed as regular maintenance on any gas detector. With the frequency depending on the sensor technology, manufacturer recommendations, specific company standard operating procedures and environment.

The two most common sensor types are NDIR and Electrochemical.

NDIR sensors tend not to drift and are calibrated prior to shipment. They require a bump testing frequency of 6 months or less to ensure performance is consistent. Calibration is only necessary if bump testing indicates the sensor is out of specification. Electrochemical sensors tend to drift over time and require bump testing every 3 to 6 months. Calibration is recommended annually or if bump testing indicates an out of spec sensor.

Due to the technology of electrochemical sensors, they will deplete over time and more rapidly if exposed to the target gas. They can also be poisoned if exposed to certain gases. If this is a risk, then bump testing more frequently is prudent. Calibration frequency can also be dependent on gas detector relevance. If it is a portable device, then it is pragmatic to bench calibrate before utilizing it in the field. If an area is planned to have significant traffic or work, then calibration should be performed for this event.

The sensor technology industry is constantly evolving, and with that newer sensors are assuring longer periods between calibration, or potentially no need to calibrate at all.

Using newly developed materials and software, sensors may last thousands of cycles without any performance decay, even if exposed to extreme environments or chemicals. The future is markedly promising.

Remember, the most important reason to calibrate your Vanguard Gas Detector is to provide accurate gas concentration readings in order that it could prevent illness, injury or death to personnel in the area. Your Vanguard may be exposed to extreme environments such as high or low temperatures, high or low humidity, or even harsh chemicals that may require more frequent calibration.  With proper maintenance, your Vanguard can provide the safety your team deserves.

Hydrostatic Level Measurement Settings for SITRANS P320/420


SIEMENS SITRANS P320/P420 pressure transmitters are digital pressure transmitters featuring extensive user-friendliness and high accuracy. SITRANS P hydrostatic level technology can handle extreme conditions and is widely used in the environmental, chemical and petrochemical industries.  SITRANS P pressure/differential pressure transmitters are extremely resistant to chemical and mechanical loads as well as commonly occurring electromagnetic interference.

SITRANS P320/420 is the first pressure transmitter on the market to feature remote safety handling. The instruments’ remote safety handling via SIMATIC PDM saves time during SIL commissioning: rather than manually programming each individual device across a facility, operators can access transmitters from the control room. This reduces the commissioning time in applications requiring functional safety. Both pressure transmitters have an increased proof test interval over other devices on the market with testing periods of up to fifteen years rather than every two. This lowers maintenance costs significantly.

Industrial Control Systems (ICS) Face New Ransomware Concern

Industrial Control System Ransomware

Dragos is a company that provides industrial asset identification, threat detection, and response to help organizations stay ahead of adversaries. According to Dragos intelligence and threat reports, it appears that a segment of code called Snake or EKANS, first recognized in December, 2019, has been designed as ransomware to target Windows systems used in industrial control systems (ICS). 

Ransomware is malicious software that will lock up data on a computer’s drive, then travel across the network and encrypt other data. The saboteurs will then demand payment in exchange for releasing the data. Whereas industrial control system machines are high-value targets (healthcare is the other high-value target) EKANS is unusual in that the malicious code uses targeted intelligence for control systems to first encrypt the root data (files are encrypted and renamed with random 5-character extension) and then ruin the software processes and hold the data hostage.

EKANS targeted companies and are sent a ransom note with the instruction to pay the ransom in cryptocurrency. There is an email address provided for contact/replies.

Manufacturing plants, power grids, and industrial concerns (such as oil refineries) are all targets of this malicious malware.

Another feature of the EKANS ransomware is it is programed to terminate sixty-four (64) various processes on computers – most of which are ICS specific.  This suggests the possibility that the EKANS may also share features similar to the Megacortex ransomware, which first appeared in early 2019.  Megacortex relies on a manual method of deployment rather than self propagation ransomware deployment.

It is still unknown whether the EKANS ransomware originated from state-sponsored hackers or via real cybercriminals trying to profit from industrial control system owners. It appears that it may be the latter, based on the most recent analysis of the nature of the ransomware – analysis by Dragos researchers.

It is wise to raise awareness with among everyone who touches your systems and it would be prudent to have someone within your organization (or a consultant) tasked with keeping data security protections current.  In addition, it is crucial to have ICS organizations rethink their cybersecurity leadership philosophy. In many organizations, the evangelists for cybersecurity are not equipped to exert influence in the company.  Cybersecurity is still treated as a back-office job, but it needs to be treated as priority by the organizational leaders.

Dragos adversary hunters recommend keeping ICS systems segmented from the rest of the network. In this way, if just one Window machine is infected, the virus can’t mobilize to the systems that control the infrastructure. In addition, standard practices such as backups, stored offline, and including the last known good configuration data will somewhat reduce the liability of slow recovery. Guardrails such as improved access and mechanisms for authentication will also help to reduce the risk of these increasingly troubling attacks on ICS systems.

An Energy Savings Solution for Domestic Hot Water in Hospitals, Hotels, Campuses, Governmental Facilities and Correctional Institutions

self-regulating technology
The Smart System: Perfectly heated water – no hot spots, no burnouts, no recirculation.

Self-regulating capabilities, environmental safeguards and a solid design make self-regulating technology the wisest choice, consistently maintaining your water supply at a prescribed temperature. The heating cable is fastened directly to the pipes, running their full length and creating a symbiotic relationship, which allows the cable to gauge any changes in water temperature. Sensing a decrease or increase in temperature, the conductive core then adjusts its own power output in response, and produces a consistent flow of perfectly heated water – no hot spots, no burnouts, no recirculation. The cable is designed to sustain nominal hot water temperatures of 105°F, 115°F, 125°F or 140°F.

Don't Risk Equipment or Safety: Freeze Protect Your Plant Now

industrial heat tracing and freeze protection
Don't let this happen at your plant.
Winter is here in its full glory. Plant engineers and plant maintenance have to pay special care in preventing freezing in pipelines, tanks, Vessels, conveyors, and impulse lines.  The cold temperatures in the Mid-Atlantic can often damage or destroy process equipment and it's valuable contents. Most commonly, pipes, instrumentation, and valves are the vulnerable items affected by the sudden drop in temperatures, causing devastating consequences, including costly downtime and unplanned outages. But there's also safety issues to be considered with snow and ice build up, so attention must be paid to snow and ice melting.

Main Categories for Industrial Heat Tracing


  • Industrial Pipe Tracing Cable
  • Industrial Tank and Vessel Heating
  • Industrial Snow Melting
  • Industrial Roof Gutter Deicing

Responsible facility management includes protecting buildings and equipment against freeze damage. There are many items in any given manufacturing plant to protect, including piping systems, process instrumentation, holding tanks, transfer vessels, and valves. For each of these items, there's a good freeze protection solution to be applied. Here are some of the more common heat tracing products used in these applications.
Self-regulating Heat Tracing Cable

Self-regulating Heat Tracing Cable

Constant Wattage Heat Tracing CableThese self-regulating, cut-to-length cables are normally installed in commercial and light industrial applications, to maintain pipe temperature and/or prevent freezing. These heating cables are available in 120 and 240 voltages and are designed for use in ordinary or hazardous locations (with proper selections and application). Typical applications for this product are freeze protection and low watt density process temperature systems such as product pipelines, fire protection, process water and dust suppression systems.

MI (Mineral Insulated) CableConstant Wattage Heat Tracing Cable

Constant wattage heater cable is ideal for use in maintaining fluid flow under low ambient conditions. The product is used for freeze protection and process temperature maintenance systems such as product pipelines, process water, dust suppression systems, lube oil and condensate return.

MI (Mineral Insulated) Cable

MI Cable is a metal sheathed cable that uses a metallic conductor as the heating element. It is custom designed and fabricated for specific applications. MI Cable is a high performance, industrial grade heat tracing cable used for applications requiring high temperature exposure, immunity to stress corrosion, high maintain temperature, under tank heating (cryogenic tanks), high power output, constant power output over entire, rugged cable construction heater length, and extended heater life.

It is critical to consider the specific application requirements for any heat tracing application. The following checklist always needs to be clearly understood:

  • The mass and material of the item being traced
  • Insulation availability - type and thickness
  • Temperature to be maintained
  • Minimum ambient temperature
  • Minimum start-up temperature
  • Available supply voltage
  • The chemical environment - expose
  • Maximum intermittent exposure temperature
  • Electrical area classification

Always share your heat tracing requirements and challenges with a process heating specialist. There are many options and product variants from which to choose. A consultation with an expert can help direct you to the safest, most efficient, and most cost effective solution.
