Silicon Piezoresistive Pressure Sensor, 0~1000kPa

Affordable price silicon piezoresistive pressure sensor supports a selectable range of 0 to 1000 kPa, features an RS485 communication interface, and IP68 protection. Its power consumption is as low as 0.88W, and the transmitter element has a temperature resistance range of -40℃ to 80℃. SUCH silicon piezoresistive pressure sensor is suitable for monitoring geological hazards such as landslides, groundwater levels, and soil pressure, as well as for assessing the bearing capacity of foundation soil, predicting road frost damage, and monitoring foundation pit water inflow and pit wall stability.

Feature

• Silicon piezoresistive sensor, along with accessories, can be installed in a drilled hole for long-term monitoring of pore water pressure within structures.
• Laser resistance trimming technology achieves zero-point and temperature compensation, ensuring stable performance over a wide temperature range.
• Strict component, semi-finished, and finished product testing and burn-in screening ensure long-term reliable measurement.
• The IP68-rated housing provides excellent water resistance, interference immunity, and environmental adaptability.
• A stainless-steel diaphragm, automatic temperature compensation, and a core calibration algorithm effectively prevent value fluctuations.
• Built-in reverse polarity protection and transient overcurrent and overvoltage protection meet EMI protection requirements, ensuring safe operation.
