HPM1670H fracturing truck special pressure transmitter using imported high precision sapphire pressure sensor, and through a specific signal extraction and compensation technology for temperature and linear calibration.Sapphire system is composed of monocrystalline silicon insulating elements, which will not occur hysteresis, fatigue and creep phenomenon;Sapphire has very good elasticity and insulation characteristics, insensitive to temperature changes, even in high temperature conditions, also has a good working characteristics.The built-in anti-jamming circuit is suitable for pressure measurement under complex conditions.The pressure interface is connected by nonren, spherical seal, flat membrane structure, easy to install and easy to use.The product is widely used in fracturing, while-drilling, cementing engineering cement and other situations, can replace the United States VTRON, Dawell, Stevenson - Stewart, Beagle and other imported fracturing truck sensors.
