The LKD13420 is a part of MPC Industries' Opto-Thermal Monitor (OTM) system designed to provide measuring, monitoring, and warning of excessive temperatures in engines and process vessels. The LKD13420 is an optical temperature sensing module with a NEMA 7 rated enclosure specifically designed for environmental hazards, such as dust, spray, oil and water. The module utilizes a pyrometer to measure the incoming infrared radiation. Relying on a thermocouple sensor, the module can measure temperatures up to 1200°C. The module also features alarm outputs, LEDs to display temperature readings, and logic power supply indicator connections.
