Pneumatic level gauge PS

watercompactautomatic

Continuous bubbler sensor for fast detection of water level changes Automatic pressure range detection for maximum measuring accuracy (0.05% FS) Display with function keys for measured value indication Measuring ranges: 0-10/17/20/30/35/40 m Long-term stability due to intelligent sensor drift compensation Available with digital (RS485: SHWP, SDI-12, MODBUS) or analog output (4-20mA, 0-1V, 0-5V) Various configuration possibilities, e.g. number of bubbles per minute, measuring cycles, etc. Including automatic blow-through, compressor and air reservoir (0.75 l) High-precision: Equipped with two pressure sensors and an automatic pressure range detection, the PS sensor also meets the highest demands on measuring accuracy. In addition, the typical, age-related drift of pressure sensors is compensated by an automatic, processor-controlled 0-point calibration before each measurement. This means that even after many years of operation, the bubbler system is just as precise as on the first day. Maintenance-free: Due to the measuring principle, the pressure measuring cell does not come into direct contact with the measuring medium water. Regular, often maintenance-intensive cleaning of the measuring cell due to deposits (e.g. lime, bio-film) is not necessary. The automatic blow-through device in the PS sensor ensures that the pressure transmission line is flushed regularly, thus preventing the bead nozzle from silting up. Safe: After the PS sensor can be safely housed in the water gauge house or switch cabinet, mechanical damage, e.g. from vandalism, flotsam, etc.
