Electro-Sensors Temp Sensors Get Conduit Adapters
Temperature sensors with new adaptors.
Minnetonka, MN — FM-approved temperature sensors from Electro-Sensors, Inc. now include a built-in conduit adapter and grease-fitting (zerk) tap. TT420-LT (Liquid Tight) temperature sensors combine a sensor, signal conditioner and loop-powered 4-20mA transmitter into a rugged and compact package. With the addition of an integrated conduit fitting, the 1/2-in. (12.7mm) TT420Z-LT and TT420S-LT models are now compatible with a wider variety of sensing applications. Plus, all models arrive ready to use, with no user calibration required.

All TT420-LT models are compatible with standard 2-wire 4-20mA current loops and analog inputs. Models vary only in their measurement probes and fittings, which are optimized for applications including grain handling facility shaft bearing (TT420Z-LT) and belt rub-block (TT420S-LT) temperature measurement. All models have an integrated fitting for 1/2-in. (12.7mm) flexible liquid-tight conduit and are FM approved as Dust Ignition-proof for use in Class II and III, Ev. 1 and 2, Group E, F, G ratings, when installed using Class II rated (1/2-in.) flexible liquid-tight conduit.

The TT420Z-LT is compatible with 1/8-in. (3.18mm) , 1/4-in. (6.35mm) and 1/2-in. (12.7mm) NPT grease fitting zerk taps. The TT420S-LT additionally screws into a brass rub-block with a 3/8-16 tap and is available with the option of a lug mount adapter, supporting a wide variety of mounting possibilities.

Applications include monitoring temperature on a wide range of industrial machinery, such as conveyors, bucket elevators, motors, gearboxes, pumps, turbines, fans, curing ovens, centrifuges, agitators, and hammermills.
