Proper temperature and humidity control in control rooms, equipment rooms, and electrical distribution rooms is crucial for the efficient and safe operation of equipment, as well as ensuring the comfort of personnel. The specific standards and recommendations for each environment are as follows: 1. Control Room Control rooms house critical systems and personnel who monitor […]
Hydrogen chloride (HCl) gas is classified under “acute toxicity – inhalation, category 3*” according to national standards. However, in practical terms, it is “not recommended” to set it up as a toxic gas for monitoring. Why is it that hydrogen chloride in its gas form is treated differently from its liquid form, like hydrochloric acid

Pressure sensors use pressure-sensitive chips (such as piezoresistive silicon membranes) to detect pressure changes. If the sensor comes into direct contact with corrosive media, the silicon membrane may be damaged, affecting performance and reducing the sensor’s lifespan. Therefore, protective packaging is required to safeguard the pressure-sensitive chip while still allowing the pressure to be transmitted

In the world of instrumentation, theoretical knowledge is like the wrench in your toolkit — it may seem insignificant, but when it fails, it can bring everything to a halt! Whether you’re preparing for an entry-level certification or simply aiming to strengthen your foundational knowledge for daily operations, the concepts of circuit diagrams, sensor principles,
Reed switch level sensors and magnetostrictive level sensors are two common technologies used for liquid level measurement. These two sensors differ in their operating principles, applications, and performance characteristics. Below is a comparison of the two. 1. Operating Principle Reed Switch Level Sensors: Reed switch level sensors operate based on the interaction between a reed

In the field, many operators have experienced this moment: despite following procedures, the moment the steam valve is opened, a dull “bang” is heard from the pipeline, the steel pipes shake, and white steam rises from the flanges… This is a classic case of steam pipeline water hammer. If not addressed immediately, it can cause
