GRAEFF GAIM series melt pressure sensors: Long-lasting stability and precise measurement

In the fields of chemical fiber production and other polymer material applications, precise pressure measurement has always been the core demand of the industry. Traditional high-temperature melt pressure sensors often have inaccurate measurements due to zero drift caused by high temperatures, which brings many troubles to the production process. Nowadays, the GAIM series of products launched by GRAEFF (Graff) has perfectly solved this problem with its innovative temperature compensation technology, bringing a revolutionary change to high-temperature pressure measurement.

1.Product Introduction

The GAIM series melt pressure sensors/transmitters are high-end products designed by GRAEFF specifically for high-temperature environments. During the process of heating from room temperature to high temperature, the zero point of traditional sensors will drift significantly due to the influence of high temperature, resulting in measurement deviation. The GAIM series products adopt advanced temperature compensation technology and perform zero drift compensation at 350℃, enabling the pressure measurement probe to approach zero temperature drift at high temperatures and significantly enhancing the accuracy and stability of the measurement.

In addition, the high-temperature resistance and high-precision measurement capabilities of the GAIM series melt pressure sensors enable them to operate stably for a long time in the high-temperature environment of the chemical fiber industry, providing reliable measurement support for chemical fiber production.

Chemical industry

There are a large number of high-temperature reactions and material transportation processes in the chemical industry. The pressure control in these processes plays a decisive role in safe production and product quality. The GAIM series melt pressure sensors are suitable for pressure measurement of various chemical media, including high-temperature liquids, gases, and corrosive media. Its high-performance diaphragm material and reliable sealing design can resist the erosion of chemical media, ensuring the long-term stable operation of the sensor in harsh chemical environments. By precisely measuring the pressure inside equipment such as reaction vessels and pipelines, accurate data support is provided for the automatic control of the chemical production process, effectively preventing safety accidents caused by abnormal pressure and ensuring the smooth progress of chemical production.

Production of polymer materials

In the production process of polymer materials, whether it is the precise monitoring of the pressure inside the reactor during the polymerization reaction stage or the real-time measurement of the melt pressure during the extrusion molding stage, highly reliable sensors are needed to ensure the safety and efficiency of production. The GAIM series melt pressure sensors, with their outstanding anti-high-temperature zero drift performance, can precisely monitor the pressure changes of the melt at high temperatures, ensuring the stability of the production process and the consistency of product quality. By precisely controlling the pressure, product defects caused by pressure fluctuations, such as bubbles and cracks, can be effectively avoided, thereby enhancing the product qualification rate and market competitiveness.


Food processing

In the field of food processing, some high-temperature processing techniques such as high-temperature sterilization and baking of food also require strict control of pressure. The GAIM series sensors can be applied to pressure monitoring in food processing equipment to ensure that the processing process meets the technological requirements and guarantees the quality and safety of food. For instance, during the high-temperature filling process of beverages, precise pressure control can prevent bottle breakage and beverage leakage, while ensuring the product's sealing performance and shelf life. During the food baking process, monitoring the pressure inside the oven can optimize the baking effect and make the food taste better.

The GAIM series sensors are also widely used in multiple fields such as petrochemicals, aerospace, and pharmaceuticals, providing reliable solutions for pressure monitoring in various high-temperature and high-pressure environments.
