1. Features and Applications: The force sensitive component of this product utilizes the silicon piezoresistive effect and is made through micro mechanical processing technology. When the sensitive component senses pressure, it will output a voltage signal that changes proportionally to the pressure. This product is suitable for measuring pore water pressure in dams and fields in the Duolei area. This product has excellent static characteristics and long-term stability. In addition, it is equipped with exclusive patented 10KV/5VA and 5KV/2KA lightning protection circuits, and has passed national lightning protection testing certification.
