Mantle sensor

Series GF-7050

General

Gräff temperature sensors of the GF-7050 series are particularly suitable for use in temperature measurement on tools, engines, cooling systems, pipelines, etc. from the fields of plastics technology, the pharmaceutical industry, power plant technology, heating and cooling technology, chemical plants and mold making. Thanks to the combination of high-quality materials, there are no limits to this series. In addition, the sheathed cable used offers the advantage that these sensors can be placed easily and precisely even in tight spaces and can be flexibly adjusted if necessary. In addition to ready-made thermal cables, different connection heads with and without transmitters, connection plugs for direct or cable connection are also possible. Thanks to the flexible and thin tube jacket, jacketed thermocouples are ideally suited for fast-response and highly accurate temperature measurements. In general, we manufacture the GF-7050 series from high-quality stainless steel or Inconel and exclusively using the laser process to exclude foreign materials. In addition to the very wide variety of diameters from 0.5mm to 6.0mm, there are also no limits to the jacket length.
