Temperature-, Measurement - and Contro Technoogy Met pressure transducers made in germany www.graeff-gmbh.com info@graeff-gmbh.com
Experience and competence made in germany We take contro. Our expertise of more than 40 years in the deveopment and production of temperature sensors has enabed us to become one of the eading manufacturers of temperature, measurement and contro systems. Our product portfoio incudes more than 5000 different active artices with more than 20000 variations. Therefore, we are in a position to cover amost a areas, where temperature, measurement and contro systems are used. Today, our sensors, contro units, contro systems, actuators, met pressure transducers as we as our products from the eectric heating technoogy range are appied in the pastics, pharmaceutica, food and raw materia processing industries wordwide. We provide countess soutions in the fieds of temperature, measurement and contro engineering to the fu satisfaction of our customers every day. Our success is mainy based on our broad expertise and our common goa of constant improvement. The organisationa structure of Gräff GmbH is speciay aimed at optimum functionaity and customer-friendy service. We-defined competences and fat hierarchies enabe short decision-making processes and quick responses to a customer requests and market situations. The company was founded in 1946 by Heinrich Gräff, the grandfather of today's Managing Partner, Marion Hupperich, as a craft enterprise. After constant further deveopment it started the production of temperature sensor technoogy in 1964 aying the foundation for our current product portfoio. We moved into the new production and administration buidings in Bonner Straße in 1985. Today, we manufacture high-quaity products with state-of-the-art machines and pants on more than 2500m². -2-
Met pressure transducers We take contro. Quaity and precision Met pressure transducers by Gräff GmbH provide high quaity and characterised by great workmanship, a ong ife cyce and versatiity. Our met pressure transducers can be used in amost a sectors of industry, where met pressure transducers required. You receive a high quaity and environmentay-friendy product that can be optimay integrated into your appication and unfods its entire performance spectrum in service. The use of first-cass materias as we as company-wide certified and monitored processes ensure a constant quaity of temperature contro units and contro systems by Gräff, which wi certainy meet your requirements. Specia soutions in the fied of met pressure transducers are not considered a probem at Gräff but rather a chaenge to be mastered.. In addition to our met pressure transducers, we aso offer temperature sensors, eectric heating technoogy, temperature contro systems and temperature contro units. You can obtain compete and perfecty aigned temperature, measurement and contro systems from a singe source. -3-
Met pressure transducers Product groups We take contro We have aso had to attend to the increasing demand for "mercury-free" pressure sensors. Pressure sensors fied with siicone oi were no rea aternative for us due to their enormous pressure differences. Therefore, we opted for an innovative iquid meta aoy with pressure transfer characteristics simiar to mercury. Thus, our product range is expanded by the pressure sensor series "GREENLINE". A known versions are aso provided in this respect. Moreover, we rey on our high quaity standard "Made in Germany" in ine with an interesting priceperformance-ratio. Detais of the respective versions can be obtained from this data sheet.

Met pressure transducers We take contro. Product groups GREENLINE series with thermoeement type J (GMDT/GL) Our combined sensor was aso enhanced with this innovative fier due to the changeover of the fier medium from mercury to the innovative iquid meta aoy. This sensor combines met pressure detection and met temperature measurement and thus ony requires one bore hoe for the sensor eement. Apart from this feature the sensor is characterised by high precision as we as our high quaity standard "Made in Germany" in ine with an interesting price-performance-ratio. The standard version of this sensor has a 1/2-20 UNF process connection. Equipment / characteristics This standard sensor can aso be instaed in the transducer bore hoe M18x1.5 (process connection) by means of reducing bushing without difficuty. fexibe pressure ranges up to1000 bar integrated thermo eement Fe-CuNi/J high precision of 0,75% v.e.. caibration signa 80% v.e. standard - process connection 1/2-20UNF (M18x1,5 via reducing bushing) eectrica standard connection incuding 6-poe connector /thermo Mercury-free Siicone-oi-free protection type IP 65 CE - certification Technica data instaation enght 152 mm output signa 3,3mV/V; 0-10VDC; 4-20mA 100% market-compatibe with a common manufacturers I non-stick membrane I I I maximum ambient temperature of eectronic system + 125 C Standard version fexibe capiaries (stainess stee corrugated hose) Integrated thermo eement according to DIN EN 60584 Fe-CuNi Typ J mercury free version process connection 1/2 20UNF-2A I siicone-oi-free version -5-
