Freezing temperatures can damage sensitive electronic pressure-measuring instrumentation, such as a pressure transducer/transmitter. Regardless of whether an operator tries their best to remove all the water from their system to prevent freezing, it is still possible that a small diaphragm cavity or pressure passage within the transducer's sensor will retain water. When this water freezes, it can cause excessive pressure on the sensor diaphragm element, exceeding its normal range of motion, and resulting in permanent distortion. Even when the ice melts with warmer temperatures, the transducer will no longer be able to return to its original zero position, making it unusable and necessitating replacement. Ashcroft, a leading manufacturer of pressure and temperature instruments since 1852, has explored this challenge extensively and offers a solution to help you prevent this from happening in your water-based applications. In this article, we will discuss what exactly happens to pressure-sensing instruments when they are exposed to freezing temperatures, the common applications where this occurs and a cost-saving solution for protecting your instruments and keeping your operation running effectively.
