RDP Electronics Ltd has additionally developed special designs where all components are welded together to ensure that there is no possibility of any parts breaking loose from the transducer.
Components such as armature and push rods are welded together and all external case components are welded to the case so that they cannot become detached over the course of time. In these applications it is also usual practice to use external signal conditioning amplifiers for the transducers.
As a further consideration transducers are usually calibrated for use with multiple amplifiers, so that in the event of an electronics failure the amplifiers can be replaced without requiring to access the transducer itself.
