The HC2A-S3 is the most versatile probe from ROTRONIC and forms the basis of the product portfolio. It measures humidity and temperature and calculates the dew/frost point.
Features of the meteorological probe
Accuracy: ±0.8 %rh, ±0.1 K, at 23 °C (10...30 °C)
Range of application: -50…100 °C / 0…100 %rh
Digital interface (UART) and scalable analog outputs, 0…1 V
Standard output scaling: 0…1 V = -40…60 °C / 0…100 %rh
Adjusted at 23 °C and 10, 35, 80 %rh
Advantages
Measures relative humidity and temperature
Outstanding accuracy, repeatability and long-term stability
Advanced probe housing and construction
Available with interchangeable sensor
Hot swappable, no calibration adjustment required due to the digital interface with Rotronic devices
Smart Electronic
Based on the Rotronic’s AirChip3000
Calculates the dew / frost point
Alarm generation
Saves adjustment data so that probes can be
interchanged without re-adjusting
Hot-swappable
Flexibility and Compatibility
User scalable analog analog ouput signals (2x 0…1V)1
Digital interface via UART2
Rapidly interfaced with HygroClip2 devices from
Rotronic or in OEM3 applications
