RVT81 – Relative Humidity and Air Temperature Sensor (Pt100 Sensor)

The RVT81 sensor is designed for precise measurement of relative humidity and air temperature in meteorological and environmental applications. Relative humidity is measured by a digital sensor, while temperature is measured by a precise Pt100 resistance sensor. The measured values are transmitted via RS485 digital communication, which allows the sensor to be integrated into FIEDLER AMS telemetry and data logging systems.

  • Measurement of relative humidity and air temperature
  • High-precision Pt100 temperature sensor
  • RS485 digital communication (FINET / Modbus RTU)
  • Stable, long-term measurement
  • Suitable for outdoor weather stations

Description

Thanks to the use of a Pt100 resistance temperature sensor, the RVT81 sensor provides higher temperature measurement accuracy than standard integrated sensors. The sensor’s design is optimized for long-term outdoor operation at weather stations.
The sensor can be easily connected to FIEDLER AMS telemetry units and data loggers via an RS485 interface.

Applications

  • Weather stations
  • Environmental monitoring
  • Agricultural applications
  • Industrial climate measurements
  • Hydrological and climatological projects
