Product Description
Meanwhile, the atmospheric pressure PO on the liquid surface is introduced to the back pressure chamber of the sensor through the gas-guide cable to offset the PO on the liquid-facing side of the sensor, so that the pressure measured by the sensor is P = Obviously, the liquid level depth H can be obtained by measuring the pressure P. The pressure signal sensed by the sensor is converted, amplified and compensated by the circuit, then converted into a standard signal for output.
