SpecialsPerspex Pressure Transducers

Designed for situations where both sides of the sensing diaphragm are to be exposed to a liquid

A transparent perspex housing allows a view of all the pathways in the transducer to ensure there are no air bubbles present.

This transducer has been produced specifically for situations where both sides of the sensing diaphragm are to be exposed to a liquid. In order to obtain good measurements it is necessary to clear the system of air bubbles. The transparent perspex housing allows a view of all the pathways in the transducer.

The sensitivity can be higher than the normal Gaeltec Devices transducers as the relatively large metal diaphragm is an active full bridge network − as opposed to the usual half bridge device with the reference half of the bridge being passive resistors in the connector.

Note: Liquids used in the transducer must be compatible with silicone rubber and perspex.
