1. A diaphragm pump comprising:
- a shaft disposed within a pump housing and coupled to at least one diaphragm;
a mount removably attached to the pump housing and having a sensor receptacle wherein a portion of the sensor receptacle extends from the mount toward the shaft; and
a proximity sensor received in the sensor receptacle of the mount such that a sensing end of the proximity sensor is flush with an end of the sensor receptacle nearest the shaft,wherein the sensor receptacle comprises a receptacle housing and a bore defined through the receptacle housing for receiving the proximity sensor, andwherein the mount is positioned at an exhaust chamber of the pump housing and exhausted motive fluid exits the pump housing via the mount.
