Temperature Sensors
Electro-Sensors provides bearing temperature sensors and surface temperature sensors designed for continuous temperature monitoring and predictive maintenance. Our sensors help detect overheating in bearings, motors, gearboxes, and pumps. Temperature monitoring is integral to the safety and reliability of conveyors, bucket elevators, and other rotating equipment to reduce downtime.
Temperature Sensor 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
- Reverse-wiring protected
- Surface Temperature Sensors for Machinery
- 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
Temperature Sensor Models
Electro-Sensors TT420 and TT420-LT (Liquid-Tight) 4-20 mA temperature monitoring 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.
Electro-Sensors TT420F surface temperature sensors can be used to monitor surface temperature on a wide range of industrial machinery including motors, gearboxes, pumps, turbines, fans, curing ovens, centrifuges, agitators and hammer mills. This surface temperature sensor is an ideal method for emphasizing predictive maintenance in your facility.
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.
