Fluid filling method for pressure transducer, involves cooling down temperature of liquid below minimum working temperature of pressure transducer and providing membranes, and closing opening when overpressure is applied to membranes

摘要

The method involves filling an inner space of a pressure transducer with liquid through a filling opening, Temperature of the liquid is cooled down below a minimum working temperature of the pressure transducer. A set of membranes (13) are provided and the opening is closed when overpressure is applied to the membranes. The opening comprises a recess into which a ball is impressed after filling the liquid.
