1. Introduction:

Melt pressure transducers are precise measuring probes which obtain their measuring accuracy and long life span only if they are properly handled. These operating instructions should be studied carefully before installing the sensor, thus ensuring a trouble-free operation

Nevertheless, should you encounter any difficulties, please feel free to contact our service technicians, who will be pleased to be of assistance

2. Operating range and field of application:

Graeff melt pressure transducers have exclusively been designed for the pressure monitoring of liquid, doughy or pasty materials at high temperatures. These must have a homogeneous constitution. The application area has to be selected in such a manner, that a max. differential pressure of 2 % of the measuring range – based on the diaphragm surface - is not exceeded.

Any use beyond the above mentioned application area does not conform to regulations.

3. Danger areas:

In the complete application area of the melt pressure transducer, there is a risk of combustion. If the pressure transducer is not installed or uninstalled correctly during the applying of pressure there is a risk of hot media emerging.

4. Waste disposal:

Pressure transducers filled with mercury, have to be disposed of as hazardous waste.

A free of charge and ecologically-friendly disposal can be carried out by Gräff GmbH

5. Transport and storage:

Gräff pressure transducers are generally dispatched in separate packages. In case of mechanical exposure, the sensing diaphragm is protected by an aluminium cap. This cap should be screwed on at all times of storage.
