Calex PyroCouple Serie Guía Del Operario página 2

PyroCouple, non-contact infrared sensors, measure temperatures from -20°C to 500°C and pro-
vide either a linear 4 to 20mA 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.
PyroCouple sensors are available as either two-wire or four-wire units.
Two-wire PyroCouple 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 PyroCouple 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 tem-
perature 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.
