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.
Researchers at Lawrence Livermore National Laboratory have published two physics-based models for the selective laser melting (SLM) metals additive manufacturing process, so engineers can understand how it works at the powder and scales, and develop better parts with less trial and error.
The Internet happened.” Those three words spoken yesterday by Marc Ostertag, North America president of B&R Automation at Pacific Design & Manufacturing, now taking place in Anaheim through Feb. 11, continues to bring ever-lasting changes to our ways of life and will undoubtedly transform manufacturing.
