In the actual acquisition process, sensors using 4-20mA current signals are quite common. The advantages of this choice mainly lie in the following aspects:

Firstly, 4-20mA current signals have stronger anti-interference and long-distance transmission capabilities during transmission. Compared to voltage signals, current signals are less susceptible to voltage drop during transmission, thus avoiding signal loss.

Secondly, the lower limit of 4mA can provide an active zero point for monitoring issues such as wire breakage. This means that when the sensor circuit breaks or has other issues, the current signal will drop below 4mA, allowing for timely detection and resolution of the problem.

Furthermore, the upper limit of 20mA meets the requirements for safety and explosion prevention. In some environments involving hazardous gases, excessive current may generate enough electrical sparks to ignite these gases, and a current limit of 20mA can prevent this from happening.

The KRACHT flow meter VC series is a flow meter with an accuracy of ± 0.3%, so it has certain requirements for the filtration accuracy of the medium. Friends who work in hydraulic stations know that if there are impurities in the oil source, it can also be a disaster for control valves such as proportional valves. Not to mention the gear flowmeter, so the front end must be well filtered, which is a basic condition for protecting the hydraulic station during the use of the flowmeter. If the signal is unstable, you should first check whether the wiring port is loose. Is the ground wire connected or incorrectly connected? If there is no signal output from the flowmeter, you can first check if the signal amplifier of the flowmeter is burnt out again. If the amplifier is good, then it is necessary to check whether the gear of the flowmeter is stuck again. If it gets stuck, you can disassemble and clean it before reinstalling it. If the gear chamber inside the flowmeter is severely stuck or rubbed during the stuck process, then this flowmeter can be scrapped on site because this situation greatly affects the accuracy of the flowmeter. If the error is not very serious, you can find a metrology institute for calibration.

Finally, 4-20mA can be powered by two wires to reduce costs. This is mainly because the current signal can be transmitted on two wires while also providing power to the sensor, thereby saving the number of wires and related costs.

In summary, sensors using 4-20mA current signals in the electrical automation industry have many advantages, including strong anti-interference ability, providing active zero points to monitor circuit problems, meeting safety and explosion-proof requirements, and reducing costs. Therefore, this signal transmission method is widely used in the measurement and monitoring of various physical quantities.
