In the vast ocean of industrial manufacturing, "force" is the core element that drives everything. From the precise pressure of chemical fiber spinning to the surging energy of high-temperature melt, the precise measurement of force directly determines the quality and efficiency of production. As a global leader in sensor technology, GRAEFF is deeply engaged in the field of pressure and temperature measurement, providing industrial customers with high-precision and high-reliability solutions with digital, intelligent and environmentally friendly innovation concepts. Today, let's uncover the technical mystery of GRAEFF sensor in the measurement of "force"!

GRAEFF is a British multinational corporation specializing in the research and development, production, and sales of pressure sensors, melt pressure sensors, temperature sensors, industrial sensors, intelligent sensors, flow sensors, intelligent sensors, displacement sensors, liquid level sensors, pressure and temperature control instruments, pressure gauges, heaters, laser technology, pressure and temperature calibration systems, the Internet of Things, and automation control systems.

 

In industrial production, there are many forms of force, and pressure, as the force per unit area, is the key monitoring object. For example, in the spinning process of chemical fiber, melt pressure directly affects the uniformity of fiber forming; In the petrochemical industry, pipeline pressure fluctuations may cause safety hazards. GRAEFF sensors transform "invisible force" into accurate data through the following technological breakthroughs:

 

 

 

 

 

 

 

 

1. High temperature resistance: GRAEFF melt pressure sensor adopts stainless steel body and titanium alloy coating, high temperature resistance up to 540°C, even in the chemical fiber production line of high temperature melt environment, still can work stably.

 

2. Environmentally friendly material innovation: Abandon the traditional mercury filling medium and adopt environmentally friendly alloy materials to reduce temperature drift, ensure measurement stability, and meet the stringent hygiene standards of the food and pharmaceutical industries.

3. Intelligent integration: Sensor and PLC, DCS system seamless connection, real-time feedback data to the control center, to achieve dynamic adjustment of process parameters, improve the level of production automation.

 

 

 

     1. Melt pressure monitoring: the "guardian" of chemical fiber production

In chemical fiber spinning systems, the installation of GRAEFF sensors covers melt filters, booster pumps, screws, spinning boxes and other key nodes. By monitoring pressure changes in real time, melt flow can be optimized, equipment overload can be avoided and service life can be extended. For example, GRAEFF high temperature melt pressure transmitters with high accuracy of 0.5%FSO have become standard in the production of polyester and nylon.

 

 

     2. Dynamic force measurement: Fusion of strain and piezoelectric technology

In addition to static pressures, GRAEFF combines strain and piezoelectric principles to develop solutions for dynamic force measurement:

(1) Strain sensor: based on the resistance change caused by material deformation, it is suitable for long-term static load monitoring, such as the load-bearing analysis of heavy machinery.

(2) Piezoelectric sensor: The use of crystal charge to respond to rapidly changing forces, specially designed for injection molding machines, stamping equipment and other high dynamic scenes, response time as low as microseconds.

 

     3. Digitalization and Internet of Things: Open a new chapter of smart factory

GRAEFF connects sensors to an iot platform for remote monitoring and predictive maintenance. For example, in oil pipelines, multi-node pressure data can be analyzed through the cloud to provide early warning of leakage risks and reduce downtime losses.

 

From the surging power of high-temperature melt to the subtle feedback of precision instruments, GRAEFF has always been driven by technological innovation to provide reliable measurement solutions for industrial customers. In the future, we look forward to working with more partners to promote intelligent manufacturing to a new height with the "power of perception"!
