Mrk engineers offers the thermalert gp series, a versatile, two piece temperature monitor system, which combines a compact, value priced monitor with an infrared sensing head. The heart of the system in the 1/8 din gp monitor, which provides advanced infrared processing capabilities including peak and valley hold, averaging and a user adjustable offset. The rugged thermalert gpr sensor is available with standard or close focus optics and provides target temperature reading with 1% accuracy. Along with its large 4 digit led display, the monitor provides a user defined 4 20 ma output and two adjustable set points/deadbands with alarm outputs, capable of driving solid-state relays. The gp monitor accepts universal 110 220 v ac power and provides a 24 vac/50 ma excitation voltage for loop power to external sensors. All monitor functions are configured via the front panel including c/f switching. The gp monitor provides adjustable emissivity and ambient compensation when used with the gpr infrared sensor. The high performance 8 to 14 micron infrared sensor with detachable cable combines current loop driven signals with 35% optics. The gp sensor is a miniature ss sensor head with 2:1 or 10:1 optics.
