Stainless-steel temperature sensor with a 2 in probe, hardwired connection and ±0.9 °F accuracy from -40 °F to 212 °F for building automation systems
This Johnson Controls temperature sensor is designed for integration with building automation systems. It provides reliable temperature monitoring for HVAC and thermostat applications in commercial or industrial environments. The probe is constructed from stainless steel with a gray housing for durability.
The sensing element uses silicon technology to maintain an accuracy of +/- 0.9 degrees Fahrenheit across the full operating span. It functions continuously from -40 degrees Fahrenheit up to 212 degrees Fahrenheit without drift. Loop resistance is specified at 1,035 ohms for stable signal transmission over hardwired connections.
The probe length is fixed at 2 inches, which dictates whether the sensor can reach the measurement point inside a duct, pipe, or equipment well. Buyers needing a longer immersion depth or a different mounting style will require an alternative model. Electrical connection is hardwired only, with no plug or quick-disconnect option provided.

The silicon sensing element is passive and produces no measurable self-heating, so the ±0.9 °F accuracy remains stable even when the sensor runs all day.
A two-wire loop with approximately 1,035 ohm resistance is required to connect the sensor to the building automation system.
The 2-inch stainless-steel probe matches standard well depths used on older Johnson Controls temperature loops, allowing direct replacement without re-piping.
