TT-420-LT Temperature Sensors

TT-420-LT Temperature Sensors

TT420-LT 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

TT420-LT (Liquid Tight) temperature sensors and fittings are optimized for grain handling facility shaft bearing (TT420Z-LT) and belt rub-block (TT420S-LT) temperature measurement. The TT420Z-LT (1/2” conduit thread) screws into a 1/8” NPT grease-fitting (zerk) tap. With their rugged integral conduit adapter, TT420-LT temperature sensors can be used to monitor a wide range of industrial machinery.

The TT420S-LT (1/2” conduit thread) models screw into a brass rub-block with a 3/8-16 tap. TT420Z-LT and TT420S-LT models come with an integrated (1/2”) conduit fitting for flexible liquid-tight conduit and are FM approved as Dust Ignition-proof for use in Class II and III, Div. 1 and 2, Group E, F, G Ratings when installed using Class II rated (1/2”) flexible liquid-tight conduit. The TT420S-LT is available with the option of a lug mount adapter. All models come ready to use right out of the box, requiring no field-calibration.
