ABSTRACT:
A pressure transducer having a first pair leads for receiving an excitation voltage and a second pair of leads between which it can supply a voltage corresponding to a pressure applied to it is provided with means for placing at least one electrical load between said first pair of leads. The leads are connected to a pressure monitor having means for indicating the pressure represented by the voltage between said second pair of leads and means for indicating an alarm condition when said signal indicates a pressure outside of a given limit. The monitor has local means for disabling the alarm indicating means and means for setting the indicated pressure to zero. The monitor also has means responsive to a first given current in said first pair of leads for disabling said means for indicating an alarm and means responsive to a second given current in said first pair of leads for causing said means for indicating pressure to indicate a zero pressure.
