PRESSURE LEVEL SENSOR
Pressure sensor technology from Keller Company

GENERAL

The water level is measured by a pressure transducer providing an electrical output proportional to the hydrostatic pressure of liquid related to the atmospheric pressure.

The sensor is generally constituted of a silicon piezoresistive or capacitive element.

The sensor is connected to the data logger with a specific cable
 
 

MEASUREMENT SPECIFICATIONS

Transmission to the logger is of 4/20 mA current loop or of true binary type through a low speed (100 bits/sec) synchronous serial transmission allowing « long distance » communications.
 

CONDITIONS OF USE

The sensor has to be strongly fixed at the bottom or at a defined level in the river bed, linked to the data logger through the connecting cable. This one should be protected in its submerged part as well as in its aerial part against damages.

Normally with this type of device the distance between the sensor and the logger can be more than 100m.
