Silicon Piezoresistive Pressure Sensor, RS485, IP68

The silicon piezoresistive pressure sensor provides an optional measurement range of 0~1000 kPa for geological disaster safety monitoring. It supports RS485 communication interface, has IP68 protection level, and is widely used in monitoring fields such as landslides, groundwater levels, and soil pressure.

Silicon piezoresistive pressure sensor provides different pressure measurement ranges of 0~1000 kPa (optional), which is mainly used to evaluate the allowable bearing capacity of foundation soil, predict the severity of road frost damage, monitor the amount of water inflow from foundation pit and the stability of pit wall.

Features

• Silicon piezoresistive pressure sensor is installed inside the borehole by adding matching accessories, and can measure the interstitial water pressure inside the structure for a long time.
• The pressure sensor uses laser resistance adjustment technology to compensate for zero point and temperature performance in a wide temperature range, and undergoes strict component, semi-finished and finished product testing and aging screening, and can measure stably for a long time.
• It uses an IP68 protective shell, which makes the sensor have good waterproof performance and anti-interference ability, and is not affected by the external environment.
• Piezoresistive pressure sensor uses a silicon piezoresistive sensor with a stainless steel diaphragm, with automatic temperature compensation and core automatic correction algorithm, which effectively prevents value fluctuations.
• It uses reverse polarity protection and instantaneous overcurrent and overvoltage protection, which meets EMI protection requirements.

Installation Example

Tips: Installation method of silicon piezoresistive pressure sensor

Put the silicon piezoresistive pressure sensor directly into the designed position of the pressure measuring tube and wrap the sensor with geotextile. If the pressure measuring tube is deep, use steel wire or thin steel wire rope to fix the sensor and tie the instrument cable to the steel wire rope. Then, slowly put the sensor into the pressure measuring tube through the steel wire rope, and finally fix the steel wire rope on the upper part of the pipe mouth to ensure that the sensor is stably in place.
