Series GF-7042/G

General

Gräff temperature sensors of the GF-7042/G series belong to Gräff special sensors, which have proven themselves over the years especially in applications for measuring the melt temperature on injection molding machines. Both the special dimensions and a special material composition characterize this sensor series. Thanks to the combination of high-quality materials and special manufacturing processes, these sensors are extremely durable and very robust. Where similar standard sensors from competitors give up, this GF-7042/G series is just beginning to show its special properties. Like all Gräff sensors, this series is also manufactured exclusively with a thermal cable instead of a compensating cable. This sensor is oil-hardened in a special manufacturing process and provided with a special coating, as a result you get an incomparable sensor with an extremely durable property! Continuous operating times of more than 50,000 continuous operating hours are unbeatable in this sensor segment! A kink protection spring complete this product.
