Compatible with the Modbus and Profibus network protocols, Raytek MI3 Series infrared temperature measurement sensors can be used in a range of applications requiring digital communication for field devices. The sensors combine an IP65 (NEMA 4) stainless steel sensing head with a separate communication module, and include a variety of sensing head temperature ranges and spectral responses, a standard USB 2.0 digital interface, a fully programmable electronics platform and response times as fast as 20 mS. They offer a choice of scalable 0/4 to 20 mA and 0 to 5/10 VDC analog outputs, or Type J, K, R or S thermocouple outputs, as well as an optional RS485 network interface. Other features include adjustable emissivity, transmissivity, peak hold, valley hold and signal averaging; and configurable inputs for emissivity control, ambient background compensation and trigger/hold input.
