HC2A-S3A standard ROTRONIC relative humidity and temperature sensor

Main features of HC2A-S3A

• Accuracy:
  ±0.8 % RV, ±0.1
  °C
  
• Application range: -50 … +80 °C/0 … 100 % RH
• digital output with UART, analogue 0 … 1 V
• diameter: 15 mm
• Length: 108 mm
• housing material: white polycarbonate (to avoid heating due to solar radiation)

Benefits

• Newer HYGROMER HM1-SK moisture sensor
• adapted for additional settings at 90% RH for more precise humidity measurements
• outstanding accuracy and repeatability and long-term stability
• can be purchased with an interchangeable sensor
• no calibration required for compliance with Rotronic instruments
• Compatibility with AC1000, RS12T and RS24T, MP102H and MP402H(HF5, HF8, HP32)

Smart electronics

• based on Rotronic’s AirChip3000
• relative humidity, temperature and dew point measurements
• generation with alarm function
• possibility to store data during sensor changeover (changeover is possible without the need for re-setting)
• the protocols used:
  • RoASCII (Default)
  • MODBUS (HW5)

Flexibility and compatibility

• possible analogue signal on the scale
• digital connection via UART
• fast connection between HC2 and Rotronic or OEM applications
