2-20 Model
Y-Case Humidity and Temperature Tranducer 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 depending on a model. It's recommended to use single or dual Shielded Twisted Pair (STP) cables to line depending on number of channels for measuring. 4-20 mA (0-10 V) connection is carried out using sealed thread M12 connector with inner terminal block (no soldering).
The transducer has SHT31 built-in sensor of temperature and humidity, that is remoted out of the enclosure to avoid heat impact coming from the motherboard. It goes with a magnet and a metal board with screws to mount.
