HVAC Temperature Sensor for Building Automation
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.
Sustained Accuracy Across Wide Temperature Range
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.
Two-Inch Probe Length Determines Fit
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.

Questions about this item
Does the stainless-steel probe generate heat that could shift its ±0.9 °F accuracy during continuous operation?
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.
What wiring must already be in place for the hard-wired electrical connection?
A two-wire loop with approximately 1,035 ohm resistance is required to connect the sensor to the building automation system.
Will the 2-inch probe fit the existing immersion wells on a legacy Johnson Controls network?
The 2-inch stainless-steel probe matches standard well depths used on older Johnson Controls temperature loops, allowing direct replacement without re-piping.
