Control Loop Accessories

Controllers and Sensors

A Control Valve is one component of a control loop and relies upon other components for proper function and operation (i.e. controller, sensor, transducer, etc.).

Type 2000 Valve Positioners (Pneumatic and Electro-Pneumatic) are mechanical devices designed to provide enhanced control, stability, and shut-off capability in extreme flow applications

Converts a milliamp current signal to a linearly proportional pneumatic output pressure. It is used in the control operation of valve actuators and pneumatic valve positioners.

Recommended for filtering and regulating the pressure of plant compressed air, and for delivering clean, dry air at the proper pressure to pneumatic control devices.

The weatherproof head provides a conduit connection and is available in cast aluminum ( screw cover), polypropylene (flip cover) and stainless steel (screw cover). The stem is either welded directly to the 1/2" NPT threaded connection, or is spring-loaded. Spring load stems must always be installed in a thermowell.

For application where the process media may be corrosive or contained under pressure to prevent damage to the sensor and to facilitate the removal from the process . To prevent leakage of the process material, spring-loaded sensors must always be installed in a thermowell.

TR890 Series Electronic PID Controller is designed for use on applications where large load changes are expected, or extreme accuracy and fast response times are needed.
