8 MOUNTING/INSTALLATION

8.1 Safety

Thermowells must be used

for all processes and flowing

media subjected to pressure.

They protect the thermometer

stem against corrosion and

mechanical damage, and

permit the thermometer to be

removed without leaks.

8.2 Preparations

(requirements for the

installation location)

• A check on suitability of the

device and of the thermowell

that may be required for the

medium to be measured, the

arrangements in the scope

of measurement range and the extent of the protection

against special conditions such as vibrations.

• A bracket must be installed to support the gauge if the

metering pipe is not able to provide adequate support

• Devices with a blow-out require a minimum spacing to

the rear (20 mm).

• The operating temperature range is -30°C to + 80 °C.

8.3 Moutning/Intallation

• Using appropriate accessories, the device can be

installed on flat walls, mounting plates, on pipes or in

panels or boards.

• Ex works, the device is supplied and calibrated for

vertical installation.

• If the installation location deviates from the vertical (max.

± 5°), the zero setting on the indicator must be corrected

(see 7.4.1 Zero point adjustment).

8.3.1 Every angle connection (optional)

Only adjust the every angle connection if this is necessary

during fitting or removal.

• Use the every angle connection to place the sensor in the

correct position prior to installation, proceeding as follows:
