ABSTRACT:
A device for monitoring the pressure of fluid in an electrically conductive duct, such as an injection duct of a diesel engine, includes at least one electrical pressure transducer connectible mechanically and electrically to the outer surface of the duct, and support means for keeping the transducer in connection with the duct. A rigid casing for surrounding and protecting the support means and the transducer is formed in two parts which are hinged together so as to clamp the transducer to the duct. This casing is constituted at least in part by an electrically conductive material and has an internal electrical connection with the output of the transducer, whereby signals output by the transducer in operation can be picked up directly by the casing.
