HART/FF Intelligent capacitive differential pressure/pressure transmitterDetailed product description：

Product Introduction

The HART/FF intelligent capacitive differential pressure/pressure transmitter is a transmission unit in the process control system, which uses a high-performance differential capacitance membrane box as the measurement sensitive element. This structure is widely used in transmitters and has the characteristics of simple structure, reliable operation, strong resistance to unidirectional overload, and high accuracy. In this product, the detected changes in capacitance are converted into digital signals through a dedicated circuit, and processed by a smart card consisting of a CPU and communication module. It can output analog signals with 4-20mA and digital signals superimposed on them, namely HART signals; It can also be connected to the FF fieldbus. The product has HART/FF communication function and various configuration functions. It can configure measurement parameters such as range, engineering unit, damping, and output function as needed, and has functions such as self diagnosis, alarm, and management information storage. It can be widely used in industries such as power, petroleum, chemical, metallurgical, textile, food, and medicine for measuring process variables such as pressure, differential pressure, flow rate, and liquid level.
