OS210 non-contact infrared sensors measure temperatures from -20°C to 500°C and provide
either a linear 4 to 20 mA output, a voltage output or a thermocouple output. This range of
output signals is compatible with almost any indicator, controller, recorder, data logger etc.,
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 not materials with a low emissivity, for example polished metals.
OS210 sensors are available as either two-wire or four-wire units.
Two-wire OS210 sensors transmit the target temperature as a 4-20 mA output and offer a
simple solution for most non-contact temperature measurement applications.
Four-wire OS210 sensors transmit the target temperature as a 0-50 mV or thermocouple
output (type J, K or T) plus the internal sensor temperature as a 4-20 mA output. This second
output can be used to ensure that the sensor is being operated within the correct ambient
temperature limits and prevent damage caused by overheating or overcooling. It can also be
used to give an approximate indication of the air temperature surrounding the sensor.
