The SIPART ® PS2 electro-pneumatic valve positioner is used to control the final control element of pneumatic linear or part-turn valve actuators. The electro-pneumatic valve positioner moves the actuator to a valve position corresponding to the setpoint. Additional function inputs can be used to block the valve or to set a safety position. A binary input is present as standard in the basic device for this purpose.
The SIPART PS2 smart valve positioner is characterized by significant advantages compared to conventional devices, such as:
Only one device version for linear and part-turn valve actuators
Simple operation and programming using three keys and a two-line LCD
Automatic startup function with self-adjustment of zero and span
Manual operation without additional equipment
Selectable or freely-programmable characteristics
Minimum air consumption
Selectable setpoint and manipulated variable limiting
This video below demonstrates how to replace an older on/off mechanical pressure switch and install the UE One Series.
The One Series electronic pressure and temperature transmitter-switches set the standard for smart digital process monitoring. With a fully adjustable set point and deadband and 0.1% repeatability, the One Series performs in a wide variety of applications. Available in Type 4X enclosures approved for intrinsic safety, flameproof and non-incendive area classifications, these hybrid transmitter-switches are designed to provide transmitter, switch and gauge functions all-in-one rugged enclosure that can withstand the rigors of harsh and hazardous environments.
Each One Series model incorporates intelligent self-diagnostics and can report detected faults before they become major safety issues. Plug Port Detection protects against sensor clogging. Nuisance trip filtering reduces false and spurious signals. The ability to capture pressure spikes and valleys provides process information to aid in the commissioning and debugging process.
The Technolog Cello 4S data logger monitors, records and transmits multiple site parameters over 2G (SMS/GPRS) or 3G networks, and provides a comprehensive multi-application solution for the Water Utilities and Industry.
The Cello 4S can have up to two pressure, eight user programmable digital or analogue inputs and two individually switched 12 Volt outputs for powering 4-20mA loops. Setup is made easy through an optional WiFi communication interface, and remote set-up, monitoring and control is facilitated through locally deployed PMAC software or web based WaterCore platform.
Technolog Cello 4S installed.
The Cello 4S provides closed loop control of pressure reducing valves, pressure sustaining valves and variable speed pumps, high accuracy battery monitoring for optimal asset management, is housed in a sturdy, portable, and waterproof to IP68 enclosure, offers 5 year battery life (typically) and includes water temperature measurement.
The Sensidyne SensAlert ASI provides enhanced protection and dependability for critical safety applications where personnel, processes, and facilities are at risk. The third-party certified SIL-2 SensAlert ASI offers dependability and versatility while remaining the easiest to install, commission, operate, and maintain.
SensAlert ASI is third-party certified to IEC61508 Level 2 (SIL-2) for both hardware and software with certification to global hazardous area and performance standards. The Test-on-Demand feature with on-board gas generator provides remote functionality checks with generated gas while Predictive Sensor End-of-Life Indication provides advanced warning of impending sensor failure.
For your convenience, we have posted the SensAlert ASI Users Manual below.
