Product Overview:
HPM420LC low power consumption level transmitter uses high quality stable pressure sensor as the measurement element, it measures the static level pressure accurately which has direct ratio with liquid depth. Then converting the measurement value into standard I2C signal through the signal conditioning circuit to achieve the measurement of liquid depth. This product has extremely low power consumption and long service life, it can use lithium-ion battery as power supply. And can connect wireless module, implement data wireless transport.
