FAQ

What problems will be encountered when using the instrument panel?

What are the precautions for using a pressure transmitter？

Prevent the deposition of debris in the conduit and prevent the transmitter from coming into contact with corrosive or overheated media.
When measuring gas pressure, the pressure tap should be opened at the top of the process pipeline, and the transmitter should also be installed at the upper part of the process pipeline to facilitate the injection of accumulated liquid into the process pipeline.
When measuring liquid pressure, the pressure tap should be opened on the side of the process pipeline to avoid sedimentation and slag accumulation.
The pressure conduit should be installed in a location with minimal temperature fluctuations.
When measuring liquid pressure, the installation position of the transmitter should avoid the impact of the liquid to prevent damage from overpressure.
When freezing occurs in winter, transmitters installed outdoors must take anti freezing measures to avoid the expansion of liquid volume in the pressure inlet due to freezing, which may cause loss of the transmitter.
When wiring, thread the cable through the waterproof joint or flexible tube and tighten the sealing nut to prevent rainwater and other substances from leaking into the transmitter housing through the cable.
When measuring steam or other high-temperature media, it is necessary to connect a condenser such as a buffer tube, and the working temperature of the pressure transmitter should not exceed the limit.

The difference between a radar single amplifier and a dual amplifier lies in the circuit. What is the difference between these two circuits？

Instruments require amplifiers to amplify signals into standard signals. A single amplifier is standard, while dual amplifiers are required for ranges exceeding 30m. The range is proportional to the number of amplifiers。
