Bulb & Capillary Thermostat for -40 deg Ambient
Bulb & Capillary Thermostat for -40 deg Ambient
(OP)
Hello,
I need to find a bulb & capillary thermostat to control a heater in a hydraulic reservoir (to maintain about +60 degrees F). This will be used in a control box where the ambient temperature could go as low a -40 degrees F (military application). Does anyone know where to find a thermostat that can handle this low of an ambient temperature on the switching side? I understand that the switching sensitivity will change at low temps due to higher viscosities of the oil in the capillary, but I need to be sure that the switches will not fail at such low temperatures. All help is appreciated. Thanks!
