Electro-Sensors, Inc.: TT-420 Temperature Transmitters

TT420 temperature transmitters, an integral part of the Electro-Sentry™ Hazard Monitoring System, combine a temperature sensor, signal conditioning and 2-wire loop-powered 4-20mA transmitter into one compact package. All models are compatible with standard I.S. barriers and PLC analog inputs and are identical with the exception of the measurement probe, of which there are 3 options:

- The TT420F mounts onto any flat surface with a #10 machine screw.
- The TT420S screws into any surface with a 1/4”- 28 tap.
- The TT420Z mounts into 1/8” or 1/4” NPT grease-fitting (zerk) taps.

TT420 temperature transmitters can be used to monitor temperature on a wide range of machinery: conveyors, bucket elevators, motors, gearboxes, pumps, turbines, fans, curing ovens, centrifuges, agitators and hammermills. All models come ready to use right out of the box, requiring no user calibration. Brass rub blocks are available for use with models TT420F and TT420S, please consult factory for more information.
