• Attachment probe, sensor and 2-wire 4-20 mA
   signal conditioner in one
• No user calibration: works right out of the box
• Reverse-wiring protected

• Compatible with PLCs, meters, and data acquisition systems
• Patented Design (TT420-LT)
• Intrinsically Safe (IS) and Dust Ignition-proof models available
• RTD Sensors with 3-wire Platinum Pt100 RTD output

Electro-Sensors TT420 and TT420-LT (Liquid-Tight) 4-20 mA temperature sensors can be used to monitor temperature on a wide range of industrial machinery including conveyors, bucket elevators, motors, gearboxes, pumps, turbines, fans, curing ovens, centrifuges, agitators and hammer mills.

RTDZ, RTDZ-LT, RTDS and RTDS-LT are resistance-output Pt100 RTD temperature sensors with 3-wire cable (specify length). The measurement probe and fitting options are optimized for many industrial applications.
