Analysis of the causes of no transmission in temperature transmitter

Temperature transmitter /

I. Temperature transmitter amplification effect Sensors and transmitters play a pivotal role in the field of instrumentation and industrial automation. Unlike sensors, transmitters can not only convert non-electrical quantities into measurable electrical quantities, but also generally have a certain amplification effect. Thermocouple temperature transmitters are generally composed of reference source, cold end compensation, amplifier unit, […]

Detailed Comparison Between Slip-On Flanges and Weld-Neck Flanges

Flange /

Flanges are essential components used to connect pipes, valves, pumps, and other equipment in a piping system. Two common types are slip-on flanges (commonly referred to as SO flanges) and weld-neck flanges (WN flanges). They differ significantly in terms of structure, welding methods, mechanical properties, and applications. This article provides a detailed analysis of these

How to Choose the Right Solenoid Valve for a Chemical Plant

Valve /

Solenoid valves are essential components in many industrial systems, including chemical plants. These valves are controlled by electric current, which powers a coil (known as a solenoid) to generate a magnetic field. This magnetic field moves a plunger that opens or closes the valve, controlling the flow of liquids or gases. In chemical plants, solenoid
