Specs At A Glance

Good To Know

Q: How does this temperature sensor work with my Thermo King unit? A: The sensor measures the temperature in the cargo area and sends an electrical signal to the control module, which adjusts the heating or cooling output to maintain the set point. Proper function is essential for accurate climate control.

Q: What is the difference between a graded and ungraded sensor? A: An ungraded sensor may have a wider tolerance range in its electrical characteristics compared to a graded one, but it is still designed to function correctly within the system's operational parameters. This provides a cost-effective replacement option for standard repair needs.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
