The P18 transducer is a device designed for the continuous measurement and conversion of relative humidity and ambient temperature into a digital way and into a voltage or current standard signal.
The transducer programming is possible through the RS-485 interface.
Applied sensor shields enable the application of the P18 transducer to operate in various ambient conditions.
The transducer is designed to be mounted on a wall.
The P18 transducer realizes following functions:
calculation of selected physical quantities (dew-point temperature, absolute humidity),
conversion of measured quantities into the output signal on the base of the individual linear characteristic,
memory of maximal and minimal value for each of measured and calculated value,
programming of the measurement averaging time,
servicing of RS-485 interface in MODBUS protocol in the RTU mode.
