1 General Information
This document contains necessary information for the proper installation and use of this
device. In addition to this instruction, be sure to observe all statutory requirements,
applicable standards, the additional technical specifications on the accompanying data
sheet (see www.labom.com) as well as the specifications indicated on the type plate.
1.1 General Safety Notes
The installation, set up, service or disassembly of this device must only be done by
trained, qualified personnel using suitable equipment and authorized to do so.
Warning
Media can escape if unsuitable devices are used or if the installation is not
correct.
Danger of severe injury or damage

Ensure that the device is suitable for the process and undamaged.
1.2 Intended Use
The device is intended to measure temperature in technical processes as specified in the
data sheet.
1.3 Conformity with EU Regulations
The CE-marking on the device certifies its compliance with the applicable EU Directives for
placing products on the market within the European Union.
The following guidelines apply to these devices:
ATEX Directive 2014/34/EU
EMC Directive 2014/30/EU
You find the complete EU Declaration of Conformity (document no. KE_041) at
www.labom.com.
1.4 ATEX Approval
If you purchased a device with ATEX approval, please refer to the accompanying
document XA_013, XA_014 or XA_021 for ATEX-relevant information.
2 Transportation and Storage
Store and transport the device only under clean and dry conditions preferably in the
original packaging. Avoid exposure to shocks and excessive vibrations.
Permissible storage temperature: -20…60 °C
3 Installation and Commissioning
Ensure that the device is suitable for the intended application with respect to temperature
range, pressure range, medium compatibility and process connection.
3.1 Mechanical Installation
Before starting operation, check the process connection carefully for leaks under pressure.
Use gaskets, if required, that are suitable for the process connection and resistant to the
media.

Measuring devices where oil or grease residues in the measuring element are not
permitted are marked on the scale with the oil can icon.
Measuring devices for use with oxygen are marked on the scale with the oil can icon
and the word “oxygen” directly below this.
3.2 Options for gas expansion thermometer
3.2.1 Operation with capillary
Route the capillary in a fixed and low-vibration manner. Note the specified maximum
permissible ambient temperature on the data sheet. Exceeding the specified temperature
limits can affect the measuring result.
3.2.2 Operation with contact sensor
Fix the slightly U-shaped temperature probe to the pipe with steel strips. Insulate the
measuring point and the temperature probe to the ambient temperature to ensure that the
measuring result is not affected. With the “adjustable display“ option it is possible to rotate
the housing around ±180° to the pipe after installation by loosening the screw connections,
thereby achieving the optimum position.
3.3 Electrical Connection
Complete the mechanical installation before you connect the device electrically. Set up all
electrical connections while the voltage supply is switched off.
3.4 Adjusting of contacts
Setting the contact can be done by using the adjustment lock in the centre of the sight
glass. Just press down the separate or permanently mounted key (Figure 1) until the
pointer of the lock catches the adjusting pin of the contact (Figure 2).
Figure 1: Key
Figure 2: Setting the contact
The set pointer can be adjusted over the entire scale range. It must be ensured that the
contact will be set in a clockwise direction only. If the contact is accidentally set behind the
desired value, turn back the contact at least 5% below the desired value and make the
setting again in a clockwise direction.
The functionality and thus the switching reliability of the built-
in switch contacts is
guaranteed within the entire nominal range. Following valid standards though the accuracy
stated in the data sheet is assured for switching points that are set between 10% and 90%
of the nominal range only.
Operating the contact outside of the scale range is not
permitted.
You can find additional information on contacts in the document TA_039, available on our
website at www.labom.com.

4 Operation
During operation, take care that the device remains within its intended pressure and
temperature ranges. No other monitoring is necessary.
The permissible ambient and media temperature depends on the type of device and its
design. This information can be found in the relevant data sheet.
4.1 Zero-point correction
Small measuring errors or deviations
caused by difference in level between
pressure gauge and point of measurement
can be corrected on measuring devices with
micro control position pointers. To do so
turn the adjusting screw on the po
inter hub
(see picture ).
Similarly, a displacement of the zero point
caused by use and long service life can be
corrected if necessary.

4.2 Maintenance / Service
When properly installed in accordance with applicable specifications, this device is
maintenance-free. However, we recommend an annual recalibration of the device.
5 Disassembly
When measuring hot media, make sure that the device has cooled down prior to any
dismounting or wear appropriate protective clothing to avoid burns.
Switch off the power supply to the device before disconnecting the electrical connections.
Once this is done, the device may be mechanically removed.
Warning
Opening pressurized lines might cause severe injuries.
Danger of severe injuries or damage

Relieve the process pressure before attempting to remove the device.
Shut off the pressure supply for all feed lines to the device
and relieve the
pressure in them.
Warning
Hazardous deposits and residues might remain on opened process
connections and removed devices.
Danger of injury

After the device has been removed, seal off the measuring point and
mark the open process connection accordingly. Consider a possible
danger due to residues when handling the removed device.
