The T-Gage line of IR temperature-gauging sensors now includes the M18T analog output model. The M18T can sense whether an object is warmer or colder than its surroundings, even when the difference is 3°C and the object is stationary. Requiring no controller to operate, the self-contained sensor includes a static or dynamic remote TEACH function. This function allows users to program two distinct temperature switchpoints for an output that automatically scales over a positive or negative slope. The M18T features an 18-mm stainless steel barrel construction and fully encapsulated electronics. The device, which is IP67-rated for operation in harsh sensing environments, is suitable for monitoring surface temperature; forewarning of overheating parts; and verifying cooking, curing, and surface temperatures. Features include a response time of 75 mls; a detection spot size of 7 to 167 mm; 0 to 10 VDC analog and PNP alarm output; and two LEDs for power on/off, TEACH, and alarm output status. The device’s analog slope direction can be changed from positive to negative or negative to positive. Engineers can choose an integrated lens for general-purpose use, an enclosed plastic face for food applications, or a germanium lens for narrow field of view. The M18T, which operates on 12 to 30 VDC, includes 2- or 9-m un-terminated cable or 5-pin Euro-style QD. The device is available with a 6:1, 8:1, or 14:1 distance-to-spot size ratio (D:S ratio).
