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.
Two new technologies from Stratasys, created in partnership with Boeing, Ford, and Siemens, will bring accurate, repeatable manufacturing of very large thermoplastic end products, and much bigger composite parts, onto the factory floor for industries including automotive and aerospace.
