Finally, the pyrobus pyrocan-pyrocouple pyroepsilon produced by Calex Electronics Co., Ltd. is a simple infrared temperature sensor with optional analog output. Without complicated settings, just connect the temperature indicator and power supply, and the measurement can be started immediately. Temperature measurement range:-20 C ~ 500 C, suitable for non-contact temperature measurement of most non-reflective nonmetallic surfaces, such as paper, thick plastic, asphalt, painted surfaces, food, rubber and organic materials. Selection of analog output for measuring temperature: double-wire 4-20 mA, four-wire 0-50 mV, four-wire J-type or T-type thermocouple. Increase the temperature output of the sensor on the four-wire product: indicate the air temperature around the sensor, which helps to prevent overheating or supercooling.
