CAL-C700 Submersible Water Level Sensor / Level Transmitter / Level Transducer is an input probe level transmitter. Based on the principle of static pressure measurement, CAL-C700 Submersible Water Level Sensor / Level Transmitter / Level Transducer uses high-precision diffused silicon sensors with features a fully sealed waterproof design, the probe will be inserted at the bottom of the liquid senses the changes in static pressure. By applying the static pressure relationship of "liquid level height × medium density × gravitational acceleration", the liquid level signal is converted into an electrical signal. After being amplified by the signal conditioning circuit and compensated for temperature, it outputs standard signals analog output, voltage output, digital output such as 4-20mA, 0-5V and RS485 etc. CAL-C700 Submersible Water Level Sensor / Level Transmitter / Level Transducer is widely used in water treatment projects, Hydrological and hydrographic monitoring, industrial storage water tank liquid level control, agricultural irrigation water level management, Environmental sewage tank monitoring and other fields.
