The Optris CT P7 infrared sensor is designed for the temperature measurement of thin plastic films, such as polyurethane, polyether sulfone, polyethylene terephthalate, Teflon, or cellulose triacetate. It has a temperature range of 32 to 1310°F and can function in temperatures up to 185°F without additional cooling. The Optris CT P7 includes D06ACCTMHS massive housing to stabilize measurements in applications with significant and short-term variations in ambient temperatures .

Selectable analog outputs and multiple digital interfaces offer high variability. Field selectable analog outputs options include 0/4-20mA, 0-5V, 0-10V, type K or J thermocouples, and alarm. The sensor includes a programmable functional input for setting external emissivity, ambient temperature compensation and reset of hold functions. It also features peak hold, valley hold, average, and an extended hold function with threshold and hysteresis .

The spectral range is 7.9μm, optical resolution 10:1, response time 150ms, and accuracy ±1% or ±2.7°F. Optional 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, 100mA max current draw, and is IP65 NEMA-4 rated. Cable lengths of 3, 8, or 15m are available .
