    The model 731 Performance Series Vapour Pressure Temperature Switches comprise of a rigid stem thermal system upon which a compression gland slides to enable various depths of thermowell (pocket) to be accomodated. This sensor is coupled to the microswitch via a precision stainless steel mechanism, the combination of which helps deliver the market leading performance customers can expect from the Series.
