In high-risk industries such as chemical and petrochemical production, automation and instrumentation systems serve as the “central nervous system” of safe operations. Hidden failures or improper configurations in systems such as DCS, PLC, SIS, and GDS can lead to serious safety hazards. This document outlines key inspection guidelines and best practices based on GB, IEC, […]
Rainwater collection systems play a crucial role in water resource reuse. Accurately measuring the water level in these tanks is essential to ensure the smooth operation of the system. Radar level gauges, a non-contact measurement technology, are widely adopted due to their high precision and reliability. However, they face specific challenges when applied to rainwater
In industrial environments, gas detection probes play a critical role in ensuring personnel and process safety. Proper installation and grounding of these devices are essential to their reliable operation. A common question among engineers and technicians is: “If the gas detector’s housing is already grounded, do we still need to ground the internal circuit?” The
Transmitters are widely used in industrial automation systems for measuring process variables such as pressure, temperature, and flow. However, during operation, transmitter failures can occur due to various reasons, posing challenges to maintenance personnel. Quickly and accurately identifying the root cause is critical for minimizing downtime. Based on years of field experience, engineers at Xingyi

🔹 1. Low Temperature Range (−200°C to 0°C) • Electron Migration is Suppressed At cryogenic temperatures, atomic thermal motion weakens, reducing the ease of electron migration from the Nickel-Chromium leg to the Nickel-Silicon leg. This leads to lower thermoelectric EMF output and reduced sensitivity. • Increased Electrical Resistance As temperature decreases, the electrical resistance of
