ISSO-WP (35-500) Vibrating Wire Piezometer
ISSO–WP (35-500) string pressure sensors are designed for long-term monitoring of fluid pressure in risers, wells, pipelines and tanks operating at high pressure. These transducers provide accurate measurement of the pore pressure of water in soils with full or partial water saturation.
The measuring range is from 0 to 350…5000 kPa (depending on the model).
Operation in aggressive environments: standard filters are made of special stainless steel with pores of 50 microns, which helps air escape from the converter housing.
The output signal is the resonant vibration frequency of the string in the range from 300 to 6500 Hz, which ensures high measurement accuracy.
