Modbus RS485 Temperature Humidity Sensor ANDARFT/R-MD/S for measuring the relative humidity and temperature in outdoor areas or indoor areas subject to high requirements and sensitive locations. The measuring transducer records the temperature and humidity via an internal sensor and converts the value into a standardized analog output signal in the range between 0-10V / 4-20 mA.
Additionally, a passive temperature sensor can be connected. The sensor ensures long-term stability and no new calibration/recalibration is required.
Additional options for sensor Modbus RS485 Temperature Humidity Sensor ANDARFT/R-MD/S (additional upgrade options):
- relay,
- additional passive temperature sensor option (NTC, PTC).
- color LED display – integrated into the robust case + displaying real-time measured values temp (°C) and humidity (%),
- upgradable with CO2 sensor (ppm) and/or VOC Air Quality sensor.
Alternative sensor versions:
- Active sensor: Outdoor Combination Sensor for Relative Humidity and Temperature ANDARFT/R-X/S.
