P18 and P18D transducer are devices destined for the continuous measurement and conversion of relative humidity and ambient temperature into a digital or analog standard signal. Additionally P18D transducer is equipped in LCD display.
The transducers programming are possible through the RS-485 interface and free eCon software.
Applied sensor shields enable the application of the P18 and P18D transducers to operate in various ambient conditions.
The transducers are designed to be mounted on a wall.
P18 and P18D realize the 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.
