Can controllers of different brands be used with the instrument?
Thread Content
For example, use the manual controller from Zhejiang University’s Zhongkong system to modify the parameters of Honeywell instruments.
If it’s the same operating system, maybe it will work!
It works. As long as the protocol is the same, for example, a domestic 475 can be used with imported instruments, and an imported 475 can also be used with domestic instruments
It has little to do with the handheld controller; it mainly depends on the protocols supported by your gauge. Nowadays, most gauges support HART, which is the most commonly used protocol. However, instrument manufacturers also have their own protocols, so it’s important to check whether the protocols supported by your handheld controller are compatible with those of the gauge. There is also a file involved – only if the handheld controller has this file can it be used
Firstly, the protocols need to be compatible, which generally isn’t a problem. Next, it’s necessary to consult the manufacturer of the handheld controller to find out whether all the options in the various submenus are supported by a particular brand and model of instrument; some settings can be quite detailed, and these vary from one handheld controller to another. However, for common tasks such as adjusting the range and zero point, there are usually no issues.
Only if it is all HART protocol can the content be viewed, but the parameters may not necessarily be able to be changed.
It depends on the communication protocol; as long as the protocols are compatible, communication is possible.
As long as the protocol is the same, it can be modified.

It is mainly related to the protocols supported by the handheld controllers; currently, the most common ones are the HART protocol, Yokogawa’s BRAIN protocol, and Honeywell’s DE protocol. Communication is possible when the protocols are the same. Honeywell has two types of protocols: one is the DE protocol and the other is the HART protocol. If it is necessary to know which protocol a sensor uses, then a controller that supports that protocol can be used for universal operation. If communication is still not possible even with the same settings, a 250-ohm resistor needs to be connected in the circuit.
