Title: Monitor and compensation system for boiler level detectors - has electronic indication of jammed float and temperature correction
Inventor: HAENLE HANS
IPC: G01F23/62
Filed: 1976-01-24
Abstract: The monitor and compensation system for inductive level transducers for boilers provides an alarm indication of malfunction of the water level float and correction for changes in water temperature. The electrical signal from the inductive pick-up (5) which is constantly varying due to the agitation of the heated water surface, is passed to a differentiating circuit. The output of the differentiator operates a level detector so that if the movement of the float ceases due to jamming of the float mechanism, a delayed alarm is given and the boiler heating shut down. In order to compensate the displacement variation of the float due to the water temperature changes, the operating shaft (3) which moves within the inductive coil, is attached to the float (2) by a temperature-sensitive metallic strip which effectively lengthens the shaft with increasing temperature.
