COMBINED ALARM PRESSURE AND TEMPERATURE FILTER Russian patent published in 2017 - IPC B01D35/14 G01L19/12 G01K7/16 

Abstract RU 2625043 C1

FIELD: machine engineering.

SUBSTANCE: filter indicator contains a housing with a cylindrical chamber equipped with a spring-loaded cylindrical piston separating the chamber into two cavities and a magnet attached to the piston. In the case on the magnet side there are stationary and movable pressure differential signalling contacts, the movable contact being made magnetically controlled. The first chamber cavity is configured to be connected to the filter inlet, the second cavity on the side of the spring is configured to be connected to the filter outlet. The magnet is fixed on the opposite end of the piston from the spring. In the body, a second chamber is provided, provided with a membrane separating the second chamber into two cavities. The first cavity of the second chamber is configured to be connected to the filter inlet, and in the second chamber of the second chamber, there are fixed and movable signalling contacts of the inlet pressure, the movable contact being connected to the membrane. A thermistor is equipped with temperature alarm contacts is fixed in the housing.

EFFECT: expansion of the functionality of the filter indicator.
