RB03 Non-contact Infrared Temperature Transmitter
(Excluding Packaging & Shipping Charges)
RB03 non-contact infrared sensors measure temperature from OOC to 12000C 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 transmitter target temperature as a 4-20mA output and offer a simple solution for most applications.
