Built for non-contact temperature monitoring in confined and hard-to-reach spaces, this infrared sensor and transmitter measures up to 500°F (260°C) with a 10:1 field of view and a 4 to 20 mA output. It uses adjustable emissivity and an adjustable alarm setpoint in a NEMA 4 (IP65) stainless steel housing. Ideal for machine and process monitoring on meters, controllers, and PLCs.
