Does Ashcroft offer a freeze-proof remedy for Ashcroft® pressure transducers?

To eliminate the problem, Ashcroft^® engineers have developed a unique modification in which a stable, emulsified lubricant is injected into the diaphragm cavity and most of the inlet passage. This viscous material displaces air and seals the cavity, thus preventing water from contacting the diaphragm and settling in the cavity. Once injected, the emulsion adheres to the inner walls of the sensor and forms a thin skin inside the inlet passage, preventing it from leaking out of the sensor, even when the transducer is mounted in the upright position.
