How to properly select and use pressure sensors
Overview: The selection and application of high-temperature melt pressure sensors, transmitters, and gauges are essential in extrusion systems. These specialized instruments play a crucial role in ensuring the quality of the melt, enhancing production safety, and protecting equipment from damage. As highly sensitive components, they require proper installation and maintenance to function effectively and deliver accurate results.
Since the 1880s, high-temperature melt pressure sensors have been considered advanced measuring tools in China. At that time, products from North America and Europe were well-established, with notable companies such as Dynisco in the U.S., GEFRAN in Italy, RKC (Physicochemical Co., Ltd.) in Japan, and NKS (Nagano) in Japan leading the market. With the continuous advancement of industrial automation in China, demand for these devices has grown significantly. Recently, several domestic manufacturers have also emerged, offering cost-effective solutions that are gaining traction in the market. One of the prominent names is Shanghai Yingying Measurement and Control Technology Co., Ltd., which has played a key role in guiding the industry toward sustainable development.
First, Common Knowledge When Choosing:
1. Brand Misconception: Many people believe that domestic products are less reliable or difficult to use. However, with the successful development of brands like Eagle, and strict quality control, this misconception is gradually disappearing. Eagle is now recognized as a top-tier domestic brand and even respected by international peers.
2. Accuracy Misunderstanding: While accuracy is important, stability is often more critical. A product’s accuracy should be based on its long-term stability rather than just short-term precision.
3. Pursuit of Cheap Options: Although everyone desires good quality at a low price, high-quality products usually come at a higher cost. It's important to balance cost and performance when making a purchase.
4. Choose the right range, accuracy, installation method, and output type according to your specific application needs.
Second, Common Sense When Using:
1. Check the size of the mounting hole and ensure it is clean before installation.
2. Install the sensor correctly and choose an appropriate location to avoid interference.
3. Clean the device carefully and keep it dry to prevent damage.
4. Avoid exposure to extreme temperatures, high-frequency signals, or static electricity that could affect performance.
5. Prevent overpressure situations that could damage the sensor.
