Rockwell Automation announces that as of December 2018, the Bulletin 837E Solid-state Temperature Switches will be discontinued and no longer for sale. Customers are encouraged to migrate to the Bulletin 837T Solid-state Temperature Sensors.

Our Bulletin 837RTD Resistance Temperature Detectors are industrial assemblies supplied with or without a temperature sensor. These sensors have a wide temperature range -50…+200°C (-58…+392°F), probe lenghths and process connections.

Our Bulletin 837T Solid-state Temperature Sensors are capable of measuring temperature in liquids, gases, and vapors from -50...250° C (-58...482° F). These sensors offer a rugged, corrosion-resistant housing and are available in display and non-display models with discrete and analog outputs. There are various process connections and ...

Our Bulletin 837 Electromechanical Temperature Controls family of condition sensing products includes rugged, industrial-grade temperature controls. These devices use vapor pressure technology to sense changes in temperature. Typical repeat accuracy is ±2 °F.
