Non Contact Infrared Temperature Sensor

Industrial IR Temperature Sensors

RB03 non-contact infrared sensors measure temperature from 0°C to 1200°C and provide a linear 4 to 20mA output. This output signal is compatible with almost any indicator, controller, recorder, data logger ect., without the need for special interfacing or signal conditioning. They are suitable for most materials such as food, paper, textiles, plastics, leather, tobacco, pharmaceuticals, chemicals, rubber, coal and asphalt; but mot materials with low emissivity, for example polished metals.

Two-wire RB03 sensors transmit the target temperature as a 4-20mA output and offer a simple solution for most applications.
