Instrumentation

In areas with acid and alkali corrosion, instrument air supply lines (compressed air pipelines) are prone to damage due to acid mist, splashes, or volatile gases, leading to gas leaks, contamination, and affecting the normal operation of instruments. Protective measures must be taken in terms of material selection, pipeline protection, installation layout, and maintenance. These […]

A lightning strike recently caused a 230 million RMB power generation unit to fail instantly—this was not a movie effect, but a real incident at a thermal power plant in Guangdong in 2023. In Dongguan alone, there were seven incidents of lightning strikes on power generation equipment, with a single loss of up to 820,000

Recommended Continuous Operating Temperature Range Note: The values below are general recommended continuous temperature ranges.Actual performance depends on compound formulation, media compatibility, pressure, and service conditions. Material Abbreviation Continuous Temperature Range Typical Applications Nitrile Rubber NBR –40°C to +100°C Hydraulic oil, fuel systems, general industrial oils Hydrogenated Nitrile HNBR –40°C to +150°C Automotive systems, high-temperature

In mechanical design and manufacturing, you often encounter tolerances marked on technical drawings, such as Φ20±0.02, 20+0.01/−0.03, or H7/g6. Almost everyone who has looked at such drawings has asked the same questions: Why are some tolerances so strict? Why are some dimensions given default tolerances, while others are specified individually? Why are geometric tolerances like

Gaskets are commonly used components in industrial equipment. But have you installed them properly? Incorrect installation can lead to gasket damage and even hazardous situations. Below is a step-by-step guide to ensure correct gasket installation. Tools You’ll Need for Installation Before starting, make sure to prepare the following tools: A calibrated torque wrench, hydraulic tightening

1. What is Sampling? Sampling refers to the process of measuring and recording a continuous-time analog signal at fixed intervals, thereby converting the continuous-time signal into a discrete-time sequence. Sampling transforms the time axis from a continuous domain into an integer-indexed domain, allowing the signal to be processed by digital systems. The sampling rate is

In the chemical industry, measuring the liquid level in sodium hydroxide (caustic soda) storage tanks has long been a challenging issue. Due to its strong corrosiveness, tendency to crystallize, and steam emissions, traditional instruments often “fail” in such conditions. In this article, we’ll explore how to address this challenge. Key Physical Parameters for Monitoring Sodium

Components of Process Control Instruments Transmitter UnitThe transmitter unit converts measured parameters (such as set parameters in an automatic control system) into standardized signals for indication, recording, or control. Common types of transmitters include pressure transmitters, differential pressure transmitters, flow transmitters, temperature transmitters, differential temperature transmitters, and level transmitters.Transmitters can be categorized into two types

In industrial settings, it’s common to hear statements like: “The equipment is still running, why shut it down?” “If we shut it down now, who will bear the loss?” “It was just repaired last year, why is it failing again?” These questions are heard every day. But what’s more difficult is the aftermath of an

When engineers first look at a piping or P&ID drawing, one thing becomes immediately noticeable:there are not many words, but there are many letter combinations. These letters are what we commonly call valve and piping codes.At first glance, they may look complicated, but in reality, they are simply a compact way of expressing technical information.
