I Product Introduction
The differential pressure transmitter is applied to prevent medium in pipes from entering into transmitter directly, and relies on capillary to link with pressure diaphragm. It is suitable to measure the liquid level, density and pressure of liquid, gas or vapor. And it converts pressure signal into 4~20mA DC digital signal. It can communicate, set up and monitor mutually with manipulator by HART protocol.
Suitable applied situations:
In petrochemical production process, differential pressure transmitter is always combined with throttling device to measure liquid, vapor and gas flow, or to detect liquid level, liquid interface and differential pressure and other parameters.
II Performance Specifications
Zero shift volume
Maximum positive migration volume: difference between migration volume upper range and measuring range
Maximum negative migration volume: measuring range lower limiting value
Measuring range
Lower range limit: -100%URL~+100%URL-Span
Upper range limit: -100%URL+Span~+100%URL
Measuring range and zero adjustment
HART manipulator, local button,communication software supported by HART protocol.
Response time
When the electrical damping of the transmitter turns off, the response time of the step input applied to the transmitter from 10% to 90% of the output range is less than or equal to 0.4s.
