Details

HygroVUE5 digital temperature and humidity sensorTemperature and relative humidity sensors are designed for routine meteorological and environmental monitoring. It adoptsUsers can replace the sensor chip components, which include a temperature sensor and a relative humidity sensor. Each component can be individually calibrated using pre stored calibration coefficients on the chip.

HygroVUE™ 5Control the measurement of sensor components through internal electronic devices, perform linearization correction on temperature readings, and useSDI-12Provide data to the data collector.

HygroVUE™ 5The stainless steel filter screen not only reduces the impact of dust and dirt on the sensor, but also ensures air circulation around the sensor element and reduces the possibility of condensate remaining inside the filter. In addition, the sensor surface is covered with a small polytetrafluoroethylene film filter to prevent dust or mold from affecting the measurement.

The sensor housing design can be exposed to any weather conditions at all times. Suitable for a range of radiation protection covers, including small protective covers such asRAD066-layer radiation shielding cover.

In order to improve reliability, sensors are installed with fixed length cables in the factory, and then the sensor body is encapsulated to seal electronic devices and cable connectors. If there are special needs, other lengths of cables can be customized.
