Process Technology Temperature Controllers

Temperature controllers are used to start and stop heaters or solenoid valves to accurately control the temperature of the solution.  Electronic and electro/mechanical controls will normally incorporate relays for the electrical loads required by the heater, relays for Protector II or III or transformers for the electronics. 
Electronic Digital Controller offer the highest reliability and accuracy - The following controllers are supplied standard with a 10 foot PTFE covered RTD sensor.  Longer length sensors are available. All units are available in a plastic box enclosure with on-off toggle, indicator light.  Combination control with 30 to 150 amp relay may include transformer and circuitry for Protector I, II or III.   Special configurations are available upon request including J &  T thermocouples for DE20 and DQ15D.

DE and DQ controllers are available mounted in a larger plastic box.  Click for details.

Custom combination controls are available incorporation level control shut off, programmable timers, alarm horns and other instruments / special components.  Please contact us with your special requirements.

Temperature Sensors:  All temperature sensors supplied for the above controllers are PTFE covered.  RTD 1000 OHM are standard for electronic controllers.  Sensors with PTFE covered sleeves are also available  for type J, K, R and T thermocouples and 100 OHM RTD.  Contact for details.
