Raytek Thermalert MI Series Compact Temperature Monitoring Systems are easy to both install and integrate into an existing process control system. The center piece of this system is the 1/8 DIN Thermalert® GP™ monitor which provides a standard interface for Raytek sensing heads including the Thermalert GPR or GPM. If a separate moni-tor is not required, the two- piece Thermalert MI sensor, or the integrated Thermalert CI sensor, provide compact solutions to infrared temperature monitoring.

When panel space is tight, the GP 1/8 DIN monitor gives you the benefits of non-contact infrared temperature measurement with no reduction in accuracy. Combined with the GPR or GPM sens-ing heads, the GP monitor system provides on-going temperature readings with a superior 1% accuracy. Adjustable offset and two adjustable setpoints with alarm outputs for tight process control are features used in the GP system along with being able to con-figure all monitor and sensor functions from the front panel. The large, 4-digit, easy-to-read display assists in taking readings at a glance.

This versatile GP system allows for the configuration of an infrared temperature monitoring system that best matches the application. If the sensor head is located near the measurement target, or the target is large, the GPM or CI is appropriate. If the measurement spot is small, or the sensor must be located further from the target, the GPR with 35:1 optics is required. The GP sensing heads range from the small to the miniature allowing you to place sensors anywhere. With the prices as low as they are, enhanced monitoring coverage can be accomplished by installing these sensors at multiple points throughout the process.

As a low maintenance solution for thermocouples, the Raytek Thermalert MI Series or CI may fit the bill. The two piece MI system with miniature sensing head and separate electronics, features adjustable Emissivity and selectable Peak Hold, Valley Hold and Averaging. The CI is a compact, integrated unit with the same output impedance as a thermocouple. It func-tions without offset error when used in tandem with the thermocouple break protection circuitry in most controllers, displays and transmitters. Both the MI and the CI are encased in rugged housings which ensure continuous, long-term performance in environments with high ambient temperatures.
