TT420 temperature sensors combine a sensor, signal conditioner and 2-wire loop-powered 4-20mA transmitter into a rugged and compact package. All models are compatible with standard 2-wire 4-20mA current loops and analog inputs

• The TT420F mounts onto any flat surface with a #10 machine screw.
• The TT420S screws into any surface with a ¼ - 28 tap.
• The TT420Z mounts into 1/8” or 1/4 ” NPT grease-fitting (zerk) taps.

Standard TT420 temperature sensors can be used to monitor temperature on a wide range of industrial machinery including conveyors, bucket elevators, motors, gearboxes, pumps, turbines, fans, curing ovens, centrifuges, agitators, hammermills and more. When used with an approved I.S. barrier, standard TT420 sensors are UL listed in the US and Canada as intrinsically safe for use in Class I (Group C, D) and Class II (Group E, F, G). All models come ready to use right out of the box, requiring no field-calibration.
