Many faults have a certain relationship with improper installation, and there will be deviations in the measurement. The same is true for capacitive pressure transmitters. As long as the use and installation according to strict technical requirements will definitely eliminate some faults.
Pressure transmitters are very familiar instruments to us. They play an important role in many fields and even in our daily life. In the process of use, some troubles will inevitably occur, except in the aging and use of machinery. Improper, due to improper installation will also cause a lot of failures, then Xiaobian for everyone to introduce the correct way of construction and installation of capacitive pressure transmitter.
1. The primary component ( orifice plate, remote transmission connector, etc. ) is blocked or installed in the wrong form, and the pressure point is unreasonable.
2. Leakage or blockage of the pressure guiding tube, residual gas in the liquid filling tube or residual liquid in the inflation tube, deposits in the process flange of the transmitter, forming a dead zone.
3. The transmitter wiring is incorrect, the power supply voltage is too high or too low, and the contact between the meter head and the meter terminal is poor.
4. It is not installed in strict accordance with the technical requirements, and the installation method and on-site environment do not meet the technical requirements.
The above faults of the pressure transmitter will cause the output to be abnormal or the measurement is not accurate. This is caused by improper installation. We should install it in strict accordance with the installation standards, take effective measures in time, and the problems can be eliminated. In case of malfunction, the transmitter should be sent to the laboratory or manufacturer for further inspection.
A gas sensor is a converter that converts a certain gas volume fraction into a corresponding electrical signal. The detector head regulates the gas sample through the gas sensor, usually including filtering impurities and interfering gas, drying or refrigeration, and processing the instrument display part.
Gas sensor is a device that converts the information of gas composition and concentration into information that can be used by personnel, instruments, computers, etc! Gas sensors are generally classified as chemical sensors, although this classification is not necessarily scientific.
