I. Product Overview:

Jing Chuan JC3351 series High temperature pressure transmitter The company is relying on the introduction of advanced technology from abroad and technology, using imported raw materials and key components, assembly and commissioning rigorous and launched with high accuracy, high performance, high stability of intelligent products.

The product is the world's most sophisticated capacitive sensor manufacturing technology, through a dedicated digital circuit and microprocessor communications module, the pressure signal is converted into a measured medium 4-20mADC An analog signal, while taking advantage of the 4-20mA A transmission line superimposed digital communication signal.

Meanwhile, the series has a variety of structural forms, a variety of corrosion protection materials, and with intelligent electronic circuit and some multi-parameter measurement and display unit conversion, the whole temperature range and full-scale automated linear tracking compensation, line adjustment, self-diagnosis, data and information storage, remote digital communications and other features. making it today's industrial process control and measurement field using the largest number of the most widely used and most stable performance, most users favor products.

Jing Chuan JC3351 series High temperature pressure transmitter Widely applied to the petroleum, chemical, steel, electricity, food, paper, textile, medicine, light industry, environmental protection and other industrial fields. Realize various media differential pressure, pressure, level and other physical measurement and control, applicable to all kinds of corrosive media and harsh environments, hazardous locations, to maximize meet customer needs.
