1. Features and Applications: The force sensitive component of this product utilizes the silicon piezoresistive effect and is made through micro machining technology. It is encapsulated in a stainless steel shell and diaphragm, and pressure transmission is achieved by filling with silicone oil. When the sensitive component senses pressure, it will output a voltage signal that varies proportionally to the pressure. This product has excellent static characteristics and good dynamic indicators, and is widely used in dynamic measurement environments. Suitable for measuring saturated and unsaturated soils, widely used in soil mechanics, civil engineering, and blasting tests, this product has strong corrosion resistance.
