The HPM1670 rotary pressure transmitter adopts an imported high-precision sapphire pressure sensor and undergoes temperature and linearization calibration through specific signal extraction and compensation techniques. Sapphire series is composed of single crystal silicon insulating elements, and will not experience hysteresis, fatigue, and creep phenomena; Sapphire has excellent elasticity and insulation properties, and is insensitive to temperature changes. Even under high temperature conditions, it has good working characteristics. This product is equipped with an anti-interference circuit, suitable for pressure measurement under complex conditions. The pressure interface adopts a union connection, spherical sealing, flat membrane structure, easy installation, and convenient use. This product is widely used in hydraulic fracturing, drilling, cementing engineering cement and other occasions, and can replace various imported hydraulic fracturing truck sensors such as Weichuang, Dawell, Stevenson Stewart, and Beijie from the United States.
