This listing is for a used fused quartz bourdon tube pressure sensor that was removed from a specialized pressure standard.  This style of sensor is one of the most accurate and stable pressure sensors in the world and have been for over 50 years.  The unit has a wound quartz bourdon tube that rotates when pressure is applied. The end of the tube is connected to a mirror that deflects a light between two photo cells.  As pressure is applied and the tube rotates, the photocells receive an uneven amount which is transmitted to a sensor board (not included).  The sensor board will then send a voltage to one of the two electromagnetics that is attached to the tube and force it back to the zero position.  The amount of current required to zero the tube is directly proportional to the pressure applied on the tube.

This sensor will require a circuit and readout in order to provide a pressure reading.  This would make a great teaching tool for an electronics or physics class.
