INTERESTING FACTS
All Gräff products are manufactured exclusively of high-quality materials from renowned raw material manufacturers. We can therefore proudly call our products “MADE IN GERMANY”. Thanks to selected, controlled raw materials manufactured in Germany we can produce high-precision and long-lasting products which have special properties. Special manufacturing methods ensuremaximum accuracy with a functional safety far beyond our warranty of 36 months. All product properties are controlled, tested and documented internally during the individual production steps and before dispatch. Continuously trained qualified personnel, state-of-the-art production technology and the processing of exclusively high-quality raw materials offer you a plus in your value-added chain.
Quality and Reliability
With an experience potential of by now 50 years in development and production of industrial temperature measurement technology, we have developed into one of the leading manufacturers of temperature, measurement and control technology. Today, with more than 80 employeesand a product portfolio of more than 5,000 different temperature sensors, we produce more than 20,000 sensor variation possibilities for the whole world at our location in Troisdorf near Bonn. With our professional competence, our know-how and our determination, we meet all conceivable temperature recording tasks from almost all branches of industry. On a daily basis we solve countless and highly-complex tasks from the sectors of temperature, measurement and control technology for the plastics, pharmaceutical, food, raw material refinement industry, metal processing, furnace construction, waste management, automobile industry, plant and machine engineering as well as the building, glass and textile industry
Competence and Know How
Established in 1946 by Heinrich Gräff, the grandfather of today's managing partner Marion Hupperich, as artisanal small business in Troisdorf near Bonn, the business developed continuously and between 1962 to 1964 laid the foundation for today's product portfolio with the production of temperature sensors. On currently more than 2500m² Gräff GmbH manufactures high-quality, precise and sustainably designed temperature measurement technology with state-of-the-art production facilities. Today, thanks to continuous market observation, our product portfolio covers temperature ensors, control technology, automation technology, actuators, electric heating technology, insulation technology, and melt pressure technology. As one of the first manufacturers on the European market, our melt pressure sensors were type tested according to current standards and certified by the TÜV Rheinland.

Resistance Thermometers
MEASURING PRINCIPLES
Gräff GmbH offers a series of platinum resistance thermometers, beginning with the tolerance classB (DIN EN 60751:2008).:These sensors have an accuracy of +/- 0.3°C at 0°C.For more accurate measurements tolerance class A (+/- 0.15°C at 0°C) or1/10 DIN class B sensors (+/- 0.03°C at 0°C).Please note that these tolerance specifications refer only to the temperature sensor and possible errors in the complete measuring chain must be observed. Equations for calculating the measuring resistance dependent on the temperature.
ndPolynomial 2 degree is defined for the temperature range from 0 to 850 °CR(T) = R0 * ( 1 + A * T + B * T2 )Polynomial 3rd degree is defined for the temperature range from -200 to 0 °C R(T) = R0 * (1 + A * T + B * T2 + C * ( T - 100°C ) * T3 )According to the standard DIN EN 60751 the following coefficients apply:A = 3.9083 * 10-3 °C-1B = -5.775 * 10-7 °C-2C = -4.183 * 10-12 °C-4bH
Platinum resistance thermometers have a high accuracy distributed across a broad temperature measurement range (from -200°C to +850°C). In their processing, pure platinum is contaminated on purpose to retain the properties of the pure metal and to make it more resistant against chemical pollution during the measurement process at the same time. In contrast to thermal elements it is not necessary to use special cables to be able to connect the sensor.
Platinum Resistance Thermometers
Resistance thermometers utilize the properties of an electrical conductor to change its electrical resistance with the temperature. The measuring principle of these sensors is to measure the resistance value of the platinum element. The most used type (Pt100) has a resistance value of 100 Ohm at 0°C and 138.4 Ohm at 100°C. Correspondingly, Pt25/Pt1000- sensors have a resistance value of 25 Ohm and 1000 Ohm at 0°C. Platinum resistance thermometers belong to the thermistors. In the case of a thermistor, the resistance increases with rising temperature.

Thermocouples
Non-isolated / welded in:
A measuring point which is connected electrically with the outer sheath.This results in improved properties in the response time of the sensor.
Potential-free / insulated:
A measuring point which is arranged insulated from the outer sheath.Penetrating moisture leads to changes of the insulation resistance and therefore to falsification of the measuring result. Our sensors are therefore generally sealed hermetically by a sealant. The measuring insert itself is also sealed to avoid penetration of moisture into the probe tube. Measuring inserts can be exchanged safely as they form a closed unit.
Colour coding according to DIN EN 60584
A thermocouple is a wire pair made of different materials which are connected at one end and part of a device which uses the thermo-electrical effect for temperature measurement. When heating up a metal, the electrons start wandering increasingly stronger dependent on the temperature. This creates a certain tension which increases in relation to the temperature increase. When using two different metals, the electrons in each material move at different speeds. As a result, one receives two different tensions. With the temperature measurement technology, only the difference tension of the two materials is measured and placed in relation to the temperature. This relationship is not precisely linear and needs to be calculated differently mathematically depending on the thermocouple. The reference junction is the connection point of the thermocouple which lies at a known (reference junction) temperature and is compared with the measuring temperature.
“ISOLATED”
Gräff GmbH generally produces all thermal elements from thermoelectric lead.Thermoelectric leads and compensating cables are used for the electrical connection between the open ends of a thermocouple and the reference junction in cases where the lines of the thermocouple are not directly connected with the reference junction. Thermoelectrical leads are produced with conductors which have the same nominal composition as the corresponding thermocouple. Compensating cables are produced from conductors which have a different nominal composition as the corresponding thermocouple.
