Temperature sensor is an instrumentation element: it measures an engine variable and reports it to the controller, which decides whether to alarm or shut down.
Before replacing, compare the reading against an external gauge and inspect the connector. Half of all "bad sensors" are loose terminals or a chafed wire to ground.
Specifications and compatibility
- Model
- EQ153 1/2 NPT
How to verify before ordering
- Match measuring range and output curve (resistance, 4–20 mA or 0–5 V) to what the controller expects.
- Check thread type and length; a sensor that does not seat leaks and reads wrong.
- Confirm maximum admissible pressure or temperature against the actual mounting point.
- The reference shown on this listing is EQ153 1/2 NPT; cross-check it against the one stamped on the removed part.
Frequently asked questions
Can I bridge the sensor to keep running?
Only as a diagnostic test, never in permanent service. Bridging removes the protection and a real fault goes unnoticed.
Why does the alarm only appear when hot?
The fault is in the sensor insulation or in the connector, which expands with temperature. Cold resistance is correct so no alarm shows.
