Low Cost Non-Contact Infrared Temperature Sensor 4-20mA(Custom -20~3200°C )

Thank you for choosing the infrared temperature sensor from Shanghai Zhengqianwang Electric Group Co., Ltd.





Shanghai Zhengqianwang's  new miniature, low-cost, high performance infrared sensor/transmitter model ZW-A features a 18 mm O.D. by 107 mm  long stainless steel housing. The ZW-A comes with a 2 m shielded cable for power and output connections. Models feature industry standard outputs that provide easy interfacing directly to all meters, controllers, dataloggers, computer boards and PLC’s. The fixed emissivity of 0.95 allows for quick and easy measurements requiring no adjustment during installation and use. Shanghai Zhengqianwang's family of infrared non-contact sensors have no drift and have high repeatability & interchangeability giving them the edge needed to increase production process speed and quality.

Maximum distance and size of measurement point
Size of measurement target and optical features of infrared thermodetector determine maximum distance between measurement target and measurement head. To prevent measurement error, the measurement target should fill field of view of probe as much as possible. Therefore, always keep measurement point smaller than measurement object or at least the same size as measurement target.
When adjust measurement target and measurement head, ensure that optical path is barrier free, as shown below:
