Inc.'s FM-approved temperature sensors 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-inch 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.
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
feature an integrated fitting for 1/2-inch 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 inch)
flexible liquid-tight conduit. The TT420Z-LT is compatible with 1/8-, 1/4- and
1/2-inch 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.
