Mechanical Specifications; Environmental Specifications - Calex PyroCouple Série Guide De L'utilisateur

PyroCouple 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. Two-wire and four-wire versions are available:
Two-wire PyroCouple sensors transmit the target temperature as a 4-20 mA output and offer
a simple solution for most applications.
Four-wire PyroCouple sensors transmit the target temperature as a 0-50 mV or thermocouple
output (type J or K) 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.
