Reliable Products Trustworthy People Temperature Sensors Features • 2-wire, loop-powered 4-20 mA analog output • Attachment probe, sensor, 2-wire 4-20 mA signal conditioner, cable, and liquid-tight conduit adapter in one • Compatible with PLCs, meters, data acquisition, and Class II hazard monitoring systems • Integral 1/2" flexible liquid-tight conduit fittings • FM approved, dust Ignition-proof • Class II and III, Div I (E, F, G); NEMA 4 TT420-LT temperature sensors combine a sensor, signal conditioner, 2-wire loop-powered 4-20 mA transmitter, cable and flexible liquidtight conduit fitting into a rugged and compact package. All models are compatible with standard 2-wire 4-20 mA current loops and analog inputs and are identical with the exception of the measurement probes and fittings. • Conveyors • Bucket Elevators • Motors • Gearboxes • Agitators • Bearings TT420Z-LT 1/4" stainless steel probe with 1/8" NPT adapter (e.g. grease fitting for bearing temperature) TT420-LT (Liquid-Tight) temperature sensors and fittings are optimized for grain handling facility shaft bearing (TT420Z-LT) and belt rubblock (TT420S-LT) temperature measurement. The TT420Z-LT screws into a 1/8" NPT grease-fitting (grease) tap. The TT420S-LT models screw into a brass rub-block with a 3/8-16 tap. TT420S-LT Straight 3/8-16 threaded stud probe (e.g. belt alignment rub block temperature) TT420S-LT Right Angle 3/8-16 threaded stud probe (e.g. belt alignment rub block temperature) TT420Z-LT and TT420S-LT models come with an integrated (1/2") flexible liquid-tight conduit fitting and are FM approved Dust Ignition-proof for use in Class II and III, Div. 1 and 2, Group E, F, G when installed using Class II rated (1/2") flexible liquid-tight conduit. The TT420S-LT is available with the option of a lug mount adapter. All models come ready to use right out of the box, requiring no field-calibration. 6111 BLUE CIRCLE DRIVE • Pumps • Turbines • Fans • Hammermills • Centrifuges Magnetic Mount Adapter Option • Accepts 3/8-16 UNC sensor thread (TT420S-LT only) • Used when permanent mounting is not practical or not possible • Solid brass for rapid temperature conduction
