ABSTRACT:
A transducer device for measuring the internal pressure in pipes, comprises two housing parts which are articulately connected with one another by a connecting element and adapted to be fixedly mounted on the pipe by means of a clamping device. Each housing part contains at least one measuring element with a bipolar take-off of the test signals. At least one pole of each take-off is electrically conductingly connected with a part of the connecting element which is electrically insulated relative to the other pole and the connecting element comprises connection terminals for the further conduction or transmission of the test signals. The other pole is potentially in direct connection with the pipe. Thereby, a convenient and easy way is created for achieving electric compensation of the interfering signals within the transducer itself, thus replacing the separate, in each case bipolar conduction of the test signals out of the two housing parts with a combined, now altogether bipolar outgoing lead for the fully compensated test signals from the transducer.
