Resistance thermometer
Installation sensor for acids and bases
Installation sensor for acids and bases
Series GF-7139
General
Gräff temperature sensors of the GF-7139 series are particularly suitable for use in measuring the temperature of acids, paints or alkalis, etc. from the fields of plastics technology, the pharmaceutical industry, power plant technology, heating and cooling technology, chemical plants and the paint industry. Due to the combination of high-quality materials, there are no limits to this series. In addition, the version with a PTFE protective tube offers the advantage that these sensors can also be screwed in directly in the process using a PTFE fixed thread. As with all Gräff sensors, this series is also manufactured exclusively with a thermal cable instead of a compensating cable. All sensor components are mainly made of high-quality PTFE or also with stainless steel 1.4571 measuring tip. This sensor is provided with a fixed thread made of PTFE as standard. Of course, this sensor design will be moisture or water resistant. This version is equipped with a cable and a cable kink protection as standard. Different cable types complete this product.
