Fire and Overheat Protection

Fire and Overheat Protection

I need something to detect fire / overheating of a transformer ( large pad mounted transformer)



The customer has been using a Fenwal 35003-38 Continuous Fire and Overheat Detector. The units are quite old. Fenwal said the boards are a 6 month lead time and are quite pricy. They have no product to substitute.



The application is: Linear heat dection wire is connected to the Fenwal control board and once a certain temperature is reached the Fenwal board closes a contact.



Does anyone have an application similar to this and suggest a manufacturer ?





Thanks

Jim,

I think Honeywell has some flame detectors (I've seen on large baking oven lines). Banner has something thats simple and inexpensive but might not be what your'e looking for:

I read this and say, use some form of infra red thermometer looking at the transformer, and at a required sepoint, trip an alarm.
