Ultrasonic level sensor

The level sensor PCTSL11x, using the ultrasonic measuring principle, records the time required for the sound wave to travel to the liquid surface and return.

As the pulse propagation speed is highly influenced by air density and so by temperature, the measurement is automatically compensated using the temperature value acquired locally by an integrated sensor.

The sensor is housed inside an enclosure with protection grade IP66/67.

The sensor uses a non-contact method of detecting level of water (or snow) and it's characterized by the absence of moving mechanical parts. This way the ultrasonic system is virtually maintenance free.

The transducer uses a 2 wires connection for power supply and for the 4-20 mA analog ouput signal proportional to level measurement. This transducer is suggested normally for distances lower than 10m.

The sensor doesn't require special installation. Generally it's placed on a mounting arm (optional) to move the sensor away from obstacles causing wrong measurements.

The configuration is made using the buttons and the display of the sensor, to adjust its performances to the site specific characteristics.
