Temperature Sensor

for DEF/AdBlue®

INCON™ brand temperature sensors detect changes in liquid temperature. The temperature sensor combines a stainless steel sensor, signal conditioner and 2-wire, loop-powered 4-20 mA transmitter into a single durable assembly.




  • Ideal for use with diesel exhaust fluid (DEF/AdBlue®) as part of a recirculation system to prevent the freezing of liquid in colder climate applications.
  • Compatible with standard 2-wire 4-20 mA current loops and analog inputs.
  • ½” NPT compression fitting included with sensor for installation purposes.

DEF/AdBlue® Recirculation Tees

The temperature sensor is installed with a reducing bell (UPP™ pipework system) or reducing bushing (APT™ pipework system) and threaded into the appropriate termination fitting as shown below. This allows the sensor to come into contact with liquid in the pipework system.
