Calex Pyro Couple Infra Red Temperature Sensor
The PyroCouple Series is a range of high quality, low cost, compact sensor-which measure the temperature of inaccessible or moving objects and materials. They measure temperatures from -20 ° C to 500 ° C, accurately and consistently, with an outstanding response time of 240 ms. PyroCouple sensors are available as
Either two-wire or four-wire units. PyroCouple two-wire sensors transmit the target temperature as a 4-20 mA output and offer a simple solution for most non-contact temperature measurement applications. PyroCouple four-wire 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 preventable damage Caused by overheating or on cooling. It Can also be used to give an approximate indication of the air temperature surrounding the sensor.
All PyroCouple sensors are fitted with precision Germanium lenses for accurate optics. Model PC21 has 2: 1 optics making it Suitable for most applications where the
Sensor can be mounted close to the target. model PC151 is designed for small or distant targets and HAS an optical resolution of 15: 1. model PC301 is designed for very small or distant targets and HAS an optical resolution of 30: 1. PCCF model is designed for targets as small as Ø5mm at a distance of 100mm from the sensor.
