A signal transducing unit which is compact and can be calibrated from outside its housing to provide zero and span adjustments after assembly with the components secured within its housing. The device has a pair of first and second elements movable with respect to each other and each having first and second ends and a conductive path, and the conductive paths of the elements electrically contact each other at a location which is displaced along their paths with the relative movement of the elements. Positioning means retains the elements for relative movement, while actuating means displaceable for moving and positioning the first element with respect to the first element controls the contact location of the elements. Adjusting means controllably sets the positions of the elements with respect to each other for a given displacement of the actuating means for providing calibration, and connecting means electrically joins with the conductive paths of the first and second elements to provide an output signal determined by the position of one element with respect to the other.
