The Optris CTlaser MT infrared temperature sensor measures temperatures through flames and glass. It is ideal for high-temperature applications such as monitoring metallic objects inside an oven, measuring chemical reactors, or testing refractory linings in kilns. Dual laser aim provides exact marking of measurement areas at any distance for objects as small as 0.06 inches .

Two models are available: the MT covers 392 to 2642°F, and the MTH covers 752 to 3002°F. Both have a 3.9µm spectral range, 45:1 optical resolution, and 10ms response time. Emissivity is adjustable from 0.1 to 1.1 .

Selectable analog outputs and multiple digital interfaces offer high variability. Field selectable analog output options include 0/4-20mA, 0-5V, 0-10V, type K or J thermocouples, and alarm. The sensor features peak hold, valley hold, average, and an extended hold function with threshold and hysteresis, all field configurable with the USB programming kit (ACCTUSBK) .

Optional plug-in interfaces include USB, RS485, RS232, 2 optically isolated relay outputs, CAN-Bus, Profibus DP, and Ethernet. The sensor operates on 8-36 VDC power supply with 160mA max current draw and is IP65 NEMA-4 rated. The Optris Compact Connect software is available as a free download .
