1. High measurement accuracy, adjustable range and zero point on-site
2. Good job stability and performance, suitable for pressure, differential pressure, liquid level, and flow measurement.
3. Second line system, nonemachineMovable componentsrepairLess quantity.
4sensorThe contact membrane material is optional and can be used for strongly corrosive or highly toxic media.
5. There are many installation and connection methods, making it convenient to connect with othersproductCompatible to achieve optimal measurement.
6. Standardsignal4-20mA output with HART protocoldigital signalRemote control, supporting upgrades to fieldbus and field control based technologies.
7. Measure viscous and easily crystallizable media at high temperatures, as well as precipitating media with solid particles or suspended solids.
According to different manufacturers, there are four ways to debug differential pressure transmitters:
1potentiometerFormula;
2. Button type(communicationExternal one click debugging based on the protocol);
3. Program menu style;
4. Communication protocol format;
(1) Potentiometer and button based debugging methods
Firstly, empty the differential pressure end of the differential pressure transmitter (connect it to the atmosphere) and adjust the zero potentiometer or long press the zero adjustment button (usually marked as "Z"); Then boost the differential pressure transmitter to full range, adjust the full range potentiometer or long press the full range adjustment button (usually marked as "S").
(2) Menu based debugging method for programs
Enter the password according to the instructions in the user manual to enter the debugging menu. Drain the differential pressure end of the differential pressure transmitter and enter the zero point debugging interface to debug the zero point; Step up the differential pressure transmitter to full range, enter the full range debugging interface to debug the full range, then save and exit.
(3) The communication protocol based debugging method selects the corresponding handheld device according to the different communication protocols. The commonly used communication protocol is the HART protocol(ROSEMOUNT and BraiN protocol (Yokogawa Yi). The commonly used handheld devices for the HART protocol include models 375 and 475, while the Brain protocol typically uses models BT200. The debugging methods vary depending on the functionality and interface of the handheld device.
