Gräff melt pressure transducers are particularly characterized by increased service life, high material quality, precise measurement behavior and food-grade transmission medium. Our sensors are completely made of stainless steel. Due to the use of a special and innovative membrane, the known defects of membrane rupture during melt shrinkage are a thing of the past.
A special coating protects the membrane against sticky and abrasive materials. The result of selected materials, a special manufacturing process and the high-precision electronic unit ensure a stable measurement process without the known disturbance variable of a temperature drift, for example with the filling medium NaK.
By eliminating environmentally harmful materials, our sensors can also be used for food and pharmaceutical applications (FDA compliant).
All Gräff melt pressure sensors are exclusively manufactured in Germany. Thus, we grant very short delivery times of max. 2 to 3 weeks. All Gräff melt pressure transducers are already available in different shaft lengths and in different capillary lengths by default.
