Abstract

A plurality of sensors are utilized to record operating conditions of the machine, element, environment, and lubricant. The apparatus is controlled either manually or with the aid of a controller unit such as a microprocessor. A stand-alone humidity sensor mechanism is disclosed, in which signal process circuitry is electrically coupled to a humidity sensor, designed to be attached to the mechanism to be monitored so that it is juxtaposed in the atmosphere above the lubricant material that is being monitored.

Claims (9)

1. A humidity sensing mechanism for use with a device desired to be lubricated, said humidity sensing mechanism comprising:

a housing carrying a lubricant and a device desired to be lubricated by said lubricant;

a humidity sensor coupled with headspace of said housing, said humidity sensor being removably coupled to said housing;

said humidity sensor measuring a percentage of saturation of water within said lubricant by measuring said air within said housing;

a first indicating mechanism;

a second indicating mechanism;

said humidity sensor communicative with said first and second indicating mechanisms;

said humidity sensor controlling said first indicating mechanism to illuminate when said humidity sensor detects saturated relative humidity levels below a predetermined unsafe level of saturated relative humidity;

said humidity sensor controlling said second indicating mechanism to illuminate when said humidity sensor detects saturated relative humidity levels above said a predetermined unsafe level of saturated relative humidity.
