CYW21Y Submersible Level Transmitter For Well Use Level Range 0~10~200mH2O Temperature Range -20~60°C Output 4~20mA, R
The CYW21Y well-type submersible level transmitter has an outer diameter of only 19mm. In addition, the internal circuit strengthens the anti-interference treatment, which effectively reduces the interference of the water pump. It is ideal for water level measurement in wells.
