Non-Filled Sensors: NHG 170 Sensor THE EXTRUSION MELT PRESSURE SPECIALISTS
In addition to answering the needs of extrusion line applications, the NHG overcomes many of the drawbacks of currently available transducers.
The NHG diaphragm is many times thicker than stainless steel diaphragms, anywhere from 4 times to 12 times depending on pressure range. This thicker construction makes the NHG diaphragm almost indestructible, an obvious advantage in extrusion plants, even if the sensor is dropped. Some uses and by products are:
NHG is also suitable for use in any extrusion process not listed above up to 350°C (662°F).

ISI now offers a non-filled sensor based on high temperature strain gauge technology. This technology overcomes many of the major drawbacks of other existing transducer technologies. Offering a combined error of less than 0.5%, negligible temperature effects and a highly durable construction, the ISI NHG represents a major breakthrough in transducer technology. Designed specifically for extrusion of food packaging, medical products and food, the ISI NHG may be used in any extrusion process up to 350°C (662°F).
The NHG sensor has a titanium diaphragm that makes it inherently corrosive and abrasion resistant in comparison to 15-5 stainless steel typically used on other sensors. Not only does this make the NHG diaphragm longer lasting, but, because the titanium diaphragm is made of a more durable material, the NHG makes possible accurate pressure measurement of a number of new processes including low glass content nylons and other mildly abrasive materials.
