Pressure Sensor Pneumatic Gauge PS-Light-2

.The SEBA-pneumatic gauge type PS-Light-2 serves as a robust,

economic and reliable measuring system for monitoring water

levels in surface waters. The measuring principle is the proportioning

or bubbler system, based upon the other well-known

SEBA instruments in the PS-series. PS-Light-2 pneumatic

gauges have proven reliable in thousands of installations in the

last 20 years around the globe.

An integrated, highly efficient mini compressor, bubbles air

through the pressure tube into the water at adjustable intervals.

The resultant pressure in the tube corresponds exactly to

the hydrostatic pressure above the mouthpiece. This tube pressure

is then measured by a very accurate pressure sensor in the

PS-Light-2. To avoid influences due to obstructions like mud in

the pressure tube, the system is blown out automatically before

each measurement.

The intermittent operation of the PS-Light-2 allows low energy

consumption, and enables operation with batteries or solar panels,

without the need for mains power supply. Together with

a long running lubricant free compressor and a system that

needs no moisture absorbers, the PS-Light-2 can be operated

maintenance-free for very long periods of time.

The basic version of the PS-Light-2 is a sensor with optional output.

However, it can be equipped with LC-display, data logger

or remote data transfer via mobile data. The basic version is delivered

in a robust protective housing (IP 65) suitable for wall or

desk mounting. SEBA PS-Light-2 can be connected to existing

pressure tubes at any time
