How do industrial devices "chat"? Let's talk about some common communication interfaces.
In a factory, weighing instruments, controllers, and PLCs not only need to perform their individual tasks but also exchange data. How do they "communicate" with each other? Through communication interfaces. Different interfaces have different strengths. Just like some people prefer making phone calls while others prefer sending WeChat messages, each has its own use. RS485: A veteran and powerful choice, RS485 is the longest-used interface in industry...

Avoid common pitfalls when selecting a weighing tower! Let's discuss some key points for choosing a weighing tower.
The market for feed tower weighing equipment is growing rapidly, with a wide variety of brands, models, and prices. Many farmers, when making their first purchase, are easily misled by complex parameters and low prices, ending up with equipment that is unsuitable for their site, lacks stability, and causes frequent problems later on, ultimately increasing costs. Based on years of frontline application experience, and setting aside marketing rhetoric, I will objectively share some insights on feed tower weighing equipment...

Valve torque testing: Why can't we just look at a single "pass" number?
I'm Lao Zhou, and I've been working in valve testing for over ten years. Today I want to talk about a phenomenon: many factories measure torque and only record the maximum value. They mark "√" for pass and "×" for fail. It seems simple and efficient, but it actually misses a lot of information. A real incident happened last year when we inspected a batch of ball valves for a valve factory. The factory inspection report showed that the torque was all within acceptable limits. But after the customer installed them...

Routine maintenance and troubleshooting of weighing tower systems
After equipment is put into use, the quality of maintenance directly determines its lifespan and measurement accuracy. A properly maintained weighing system can easily operate stably for more than five years; conversely, even with appropriate equipment selection, various problems may arise within a year. This article outlines key considerations for practical operation from the perspectives of daily maintenance and troubleshooting. I. Daily...

The valve testing equipment has been used for five years. Should it be replaced?
A friend asked me the other day: their factory's valve testing equipment is five years old and still usable, but it feels outdated. He asked if they should continue using it or replace it with a new one. This is a common question. The equipment has been used for several years, it's not broken, but it always feels like something's not quite right. Should it be replaced? I talked to him...
