ABSTRACT:
A condition responsive sending and indicating unit for sensing a condition and transmitting a signal representative of the sensed condition to an indicator at a remote location. The sending unit includes indicia for giving an indication of the sensed condition at the site of the unit, and has a movable contact operatively associated with a variable resistor in circuit with the remote indicator, whereby a variable signal is produced in response to variation in the sensed condition. Calibration of the unit is accomplished by adjustment of the set point of the movable means, and by adjustment of the position of the resistor relative to the movable contact.
