     humidity transmitter

    • temperature
    • barometric pressure
    • relative humidity
    • dew point temperature
    • absolute humidity
    • specific humidity
    • mixing ratio
    • specific enthalpy

    Measured temperature, barometric pressure, relative humidity, dew point temperature, absolute humidity, specific humidity, mixing ratio or specific enthalpy is converted to digital serial output with the RS485 or RS232 link parameters. Large dual line LCD for simultaneous display of temperature and relative humidity, or other calculated humidity interpretation is an advantage. Computerized design ensures maximum long term stability and fail indication. The transmitter works with ModBus communication protocol or with Advantech ADAM compatible protocol. Protocol is user selectable in special configuration mode by means of the PC. Serial link enables to read actual readings and modify transmitter configuration. Instrument works always in slave mode, i.e. responds only to master device query. Transmitters have the address space available from 1 to 255. The T4311 RS232 transmitter can be powered directly from the PC port or from external ac/dc adapter.

    State-of-the-art capacitive polymer humidity sensor excels in mechanical stress, temperature shock, dew resistance as well as in large linearity range and low hysteresis. Transmitters are designed for use in non-aggressive environment.
