Description

I. usage

The monocrystalline silicon pressure transmitter adopts high accuracy, high overvoltage and strong stability of monocrystalline silicon sensor technology, embedded intelligent powerful signal processing module, realize different temperature automatic compensation, not affected by temperature and high overpressure, improve the comprehensive measurement accuracy and long-term stability of the site. Intelligent integrated design of transmitter, equipped with liquid crystal display and keypad, can transfer positive and negative points without pressure source, set range and damping time, and improve on-site adjustment function of products. Widely used in various industrial automatic control environment, involving water conservancy and hydropower, railway transportation, intelligent building, production automation, aerospace, military, petrochemical, oil wells, power, ships, machine tools, pipes, medical, food and many other industries.
