KQS-BYX-WS Stevenson Screen Sensor with Wide Voltage Power Supply High Accuracy Measurements and RS485 Output

The KQS-BYX-WS Stevenson screen environmental sensor integrates temperature, humidity, and atmospheric pressure measurements. The atmospheric pressure sensing element uses a piezoresistive silicon micro-pressure sensor. The humidity sensing element uses a capacitive polymer moisture-sensitive component. The temperature sensing element uses a band-gap-based temperature sensor.

All temperature and humidity chips are fully calibrated across the entire measurement range. The device offers high accuracy, fast response, strong anti-interference capability, and excellent long-term stability. The signal transmitter adopts an advanced integrated circuit module and RS485 output, ensuring that measurement accuracy is not degraded during transmission.

The instrument is compact, easy to install, portable, and highly reliable. It is widely used in meteorological observation, environmental control, agriculture, factories, and other fields.

• Factory dual calibration for high measurement accuracy
• Secondary linear calibration ensures stable and consistent data output
