TT420 temperature sensors are used to monitor temperature on a wide range of industrial machinery including liquid  tanks, piping, conveyors, bucket elevators, motors, gearboxes, pumps, turbines, fans, curing ovens, centrifuges, agitators, hammermills, and more.

TT420 temperature sensors combine a sensor, signal conditioner and 2-wire loop-powered 4-20 mA transmitter 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.

Features:
• 2-wire, loop-powered 4-20 mA analog output
• Attachment probe, sensor, and 2-wire 4-20 mA signal conditioner in one
• No user calibration: works right out of the box
• Compatible with PLCs, meters, and data acquisition systems
• Reverse-wiring protected
• UL listed, Intrinsically Safe (IS) Class I, Div I (C, D) and Class II, Div I (E, F, G)

3 Models:
• TT420F -  flat surface mount-  mounts onto any flat surface with a #10 machine screw (included)
• TT420S -  1/4-28 threaded stud- screws into any 1/4-28  tap
• TT420Z* -  1/4 in stainless steel probe -  often used with compression fitting mount (tanks, piping, bearing zerk grease fittings)

*Available with or without compression fitting adapters
