4. Assembly / installation / disassembly
4.1 Storage
Storage temperature range: -40°C to +70°C, rel. humidity <95%
4.2 Packaging and transport
In order to achieve optimal measurement results with our sensors, ensure the
protective cap remains intact to protect the sensor tip.
Any damage to the sensor can result in incorrect measurements or failure, in addition
defects can occur on your machines due to damaged melt temperature sensors.
4.3 Installation instructions
Observe the applicable national regulations when selecting line materials, and for the
electrical connection of the device.
The electrical connection should only be executed by specialized personnel.
The devices that bear the CE mark satisfy the requirements of the EU Directive
89/336/EEC "Electromagnetic Compatibility" and the harmonized European
standards that are listed there. The EU Declarations of Conformity are available for
the responsible authorities in accordance with the aforementioned EU Directive,
Article 10.
4.4 Assembly / commissioning
Remove the sensor from the packaging and inspect for transport damage (leave the
protective cap in place for all further transport!).
Test for function using an ohm meter, a resistance of 1…20 ohm must be displayed
(line dependent) when connecting the thermal line.
For resistance thermometers a value of approximately 108 ohm (+/-5 ohm) must be
displayed here.
Verify the dimensions/specification: diameter, sealing area, sword length, thread, and
line length
When assembling the melt temperature sensor ensure that the sensor mounting hole
corresponds to the dimensions listed on page 10. The fit precision can be checked
using a test bolt. Prior to installation heat-resistant grease must be applied to the
sensor thread. If the machine part with the receptacle bore is still at production
temperature then a warm-up time for the sensor must be taken into consideration.
Due to thermal expansion the sensor would be firmly seated. When screwing into
place ensure that the sensor is not tilted or does not fall into the hole.
In the final assembly there should be as little cavitation (material residues, material
contaminations etc.) as possible, the sensor point should still project into the machine
interior. In addition the thread should demonstrate freedom of movement, be free of
product remnants, and it should be absolutely clean.
