Osmotic pressure monitoring

Osmotic pressure monitoring is used to measure water level and water temperature, and is widely used in the measurement of void water pressure in various engineering fields.Osmotic pressure monitoring (piezoresistive pore water pressure gauge) 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 to overcome the limitations of traditional analog circuit modules. Disadvantages: It can realize full-scale digital linear correction and full-temperature zone digital temperature error compensation; the compensation parameters are stored in non-volatile memory, and multiple security protection mechanisms avoid the product being unusable due to the loss of calibration parameters; the circuit module has a power supply Monitoring and watchdog monitoring functions, and the investment-type structure is fully stainless steel sealed, which greatly improves the reliability of the product.
