4.1 Overview
Capacitive flanged differential pressure or pressure transmitter was
connected by flange and the parts to be tested. It was applied to the conditions
as below.
①
Put the high temperature medium and transmitter in insulation.
②
The measured medium is corrosive to the transmitter sensitive element.
③
The measured medium is suspension liquid or with high viscosity.
④
The measured medium is easy to solidify because of the changing of
environment or temperature.
⑤
Use the measuring head that will be purified strictly to replace the
measured medium.
⑥
Make sure the measuring head is cleaned. Capacitive flange
differential pressure or pressure transmitter will be used to measure the
differential pressure parameter of liquid, gas and vapor and the liquid level,
interface and density of liquid. The measuring head can measure the flow rate
of gas, liquid and vapor and put the measured signal changed into 4
～
20mA
DC two-wire system signal output together with orifice set, which will be
regarded as instructions, records and the input signal of regulator to constitute
automatic detection, records and controlling industrial automation system
together with other instruments or industrial controlling computer.
