Osmotic pressure monitoring station

The seepage pressure monitoring stationis also called the underground seepage pressure monitoring system and the integrated pore water pressure monitoring station. The seepage pressure monitoring station mainly conducts real-time automated monitoring of underground seepage pressure in soil landslides. It is also used for long-term monitoring of water levels in reservoirs, rivers, lakes, etc. amount of change. The FT-SY1 osmotic pressure monitoring station is a hydrological instrument used for water level and water temperature measurement. It is developed through years of accumulation of production technology and using advanced mixed signal processing technology. It overcomes the shortcomings of traditional analog circuit modules and can achieve Full-scale digital linear correction, full-temperature zone digital temperature error compensation; compensation parameters are stored in non-volatile memory, and multiple safety protection mechanisms avoid the product being unusable due to loss of calibration parameters; the circuit module is equipped with power monitoring and gatekeeping The dog monitoring function and the input-type structure are all stainless steel sealed, which greatly improves the reliability of the product.
