Resistive Temperature Detectors (RTDs)
Cat Generators may be equipped with resistance temperature detectors for generator bearings. These detectors are 100 ohm resistance temperature detectors. A resistance temperature detector may be monitored by the optional monitor for the Electronic Modular Control Panel (EMCP) resistance temperature detectors. A resistance temperature detector may be monitored by equipment that is provided by the customer. Consult with your Cat dealer about other methods of measuring the bearing temperature.The EMCP may be configured to "ALARM" or "SHUTDOWN". An alarm is activated if the temperature of the bearing reaches 85 °C (185 °F). A shutdown occurs if the temperature of the bearing reaches 95 °C (203 °F).Infrared Thermometers
Bearing temperatures can also be recorded with the use of an infrared thermometer. Refer to Special Publication, NENG2500, "Dealer Service Tools Catalog" for various infrared thermometers. Follow the instructions that come with your infrared thermometer.
