Humidity transmitter HG010.65
Computerized design ensures maximum long term stability, temperature compensation of the
humidity sensor and fail indication. Measured quantities are converted to digital serial
output with the RS485 or RS232 link parameters. Communication protocol is Advantech
standard ADAM compatible. Measured values can be in Engineering units or floating decimal
point format (IEEE754). It is possible to read the transducer configuration, its type,
firmware version, modify the communication parameters including activation of CRC and
transducer calibration. Sensor breakage or short circuit is indicated. RS485 transducers
have the address space available at the range of 0-255.
State-of-the-art capacitive polymer sensor excels in mechanical stress, temperature shock,
dew resistance as well as in large linearity range and low hysteresis. Air humidity
transducers are designed for use in non-aggressive environment.
APPLICATIONS - measuring and control of air relative humidity at:
- - warehouses
- - glasshouses
- - manufacturers
- - museums, archives, galleries
- - air-conditioned rooms
- - weather stations
