The electrical interfaces of field instruments have many specifications and sizes depending on the manufacturer and application scenarios… Domestic and foreign, metric, imperial, sealed and non-sealed, who is not confused when encountering them? This article mainly introduces the two specifications of M20×1.5 and 1/2″NPT that are often encountered by instrument engineers and are easily confused. […]
When there is no medium flow, the flow meter may produce small flow fluctuations due to some reasons, such as pipe vibration, installation stress, electromagnetic interference, or medium disturbance caused by changes in working conditions. The flow meter sensor is prone to introduce false interference signals. Measured values, these “false flow” cannot truly reflect the
When electrical instrument workers (especially maintenance electricians, instrument workers, etc.) perform control panel wiring, troubleshooting, and maintenance, the most indispensable thing is the line number tube. In the process of wiring electrical instruments, wire tubes are an indispensable and important component. Mature wiring technology is certainly inseparable from wire number tubes, but in actual application,
Many instrument workers do not pay attention to the precautions when using signal tubes! Read More »
1: What impact does instrument hygiene have on instruments? 1. Accuracy: Keeping the meter clean can prevent contaminants from interfering with measurements and ensure the accuracy of meter readings. 2. Reliability: Clean instruments can reduce the probability of failure and improve the reliability of their work. 3. Service life: Good hygiene can help extend the

Toxic and flammable gas leaks pose a constant threat to industrial plants, their employees, and those who live nearby. Continuous, reliable operation of equipment and your familiarity with gas detection systems are also critical. There are some common units and common terms involved when using gas detectors. Do you know what they are? Common
An important feature of modern chemical production is the large-scale and highly automated production equipment. Automation is the basic condition and important guarantee for the safe operation, smooth operation and improvement of efficiency of production equipment. However, with the development of production and the improvement of automatic control level, the corrosion problem of chemical instruments

The anti-explosion protection class II 2G Exdb IIB/IIC T* Gb, ATEX indicates that the flowmeter is suitable for use in areas where there is a risk of explosion due to gases (Zone 1, for example). This classification means the device is designed to prevent ignition of surrounding explosive atmospheres and is constructed to a high
Modbus and ProfiNET represent different stages of development of industrial communications, each with its own advantages and disadvantages. Modbus is simple and easy to use, suitable for small systems; ProfiNET is efficient and stable, suitable for large and complex networks. Converting Modbus to ProfiNET can improve system performance and scalability. In actual scenarios, the production
Why Modbus needs to be converted to ProfiNET Read More »
1. The orifice flowmeter should be equipped with a section of measuring tube during installation. At least one 10DN and a second 5DN straight pipe section should be maintained to improve measurement accuracy. 2. If valves need to be installed before and after the orifice flowmeter, it is best to choose a gate valve and
