08a Model
Z-Case humidity & temperature transducer uses 4-20 mA (0-10 V) analogue interface to transfer data. The probe connects to 4-20 mA (0-10 V) line by 2, 3 or 4 wired scheme with a outside power supply depending on a model. It's recommended to use single or dual Shielded Twisted Pair (STP) cable for lines depending on number of channels for measuring. It connects to 4-20 mA (0-10 V) line using screw terminals being inside the industrial enclosure.
The transducer consists a free hex fitting М20х1,5 / G1/2 and a copper washer.
The external humidity and temperature SHT31 sensor is remoted out of the transducer to avoid heat impact coming from the board.
