Temperature sensors include a built-in conduit adapter and grease-fitting (zerk) tap
Temperature sensors combine a sensor, signal conditioner and loop-powered 4-20mA transmitter into a rugged and compact package.
FM-approved temperature sensors from Electro-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 4-20 mA transmitter into a rugged and compact package. With the addition of an integrated conduit fitting, the 1/2-in. 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 4-20 mA 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-in. 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-, 1/4-, and 1/2-in. 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 conveyors, bucket elevators, motors, gearboxes, pumps, turbines, fans, and more.

Annual Salary Survey
Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.
There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.
But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
