White plastic conduit-box sensor with 8 ft averaging probe

Johnson Controls Inc

Johnson Controls Inc air conditioning

SKU CH-9BZD-KNDZK

8 ft duct temperature sensor with ±0.34 °F accuracy from -50 °F to 220 °F, 1000 ohm nickel element for building automation systems

  • Accurate readings within ±0.34 °F across wide range
  • Operates reliably from -50 °F to 220 °F
  • 8-foot averaging probe captures duct temperature evenly
  • 1000 ohm nickel element suits building automation systems
  • Hardwired conduit-box design simplifies permanent installation

Temperature Sensor for Building Automation

The Johnson Controls TE615P1 is a duct temperature sensor built for building automation systems. It uses a nickel sensing element with a 1000 ohm loop resistance to provide accurate temperature readings. The sensor mounts inside a white plastic conduit box and connects via hardwired electrical terminals. It is designed for professional HVAC control and monitoring applications.

Replaces Ageing or Failed Duct Sensors

This unit serves as a direct replacement for worn nickel-element sensors that have drifted out of calibration. The jump is worth it when an existing probe no longer holds the required +/- 0.34 degrees F accuracy across the operating range. An 8 ft averaging probe length ensures a representative sample of duct air temperature. Hardwired connections eliminate plug corrosion issues common in older installations.

Suits Technicians Maintaining BAS Loops

This sensor suits technicians maintaining building automation loops that require a 1k ohm nickel curve. It covers a broad sensing span from -50 to 220 degrees F for year-round operation. Buyers who need a different resistance curve or a wireless transmitter should look at other models. Installers without conduit-box mounting provisions will need an alternative housing style.

Questions about this item

What size conduit box or opening does the sensor housing need for mounting?

The sensor uses a white plastic conduit-box housing designed for standard electrical-box mounting; no special cut-out size is stated.

How is the 8 ft averaging probe installed in the duct, and what step is often missed?

Insert the full 8 ft probe into the duct so it averages temperature along its length, then secure the conduit box; the step often missed is ensuring the entire probe lies in the airflow rather than coiling it inside the box.

When should the sensor be replaced, and what indicates it is out of calibration?

Replace the sensor if readings drift beyond the stated ±0.34 °F accuracy across the –50 °F to 220 °F range or if the 1000 ohm loop resistance measures significantly different from 1k ohm.
