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.

You find the complete EU Declaration of Conformity (document no. KE_040) at
www.labom.com.

1.4 ATEX Approval

If you purchased a device with ATEX approval, please refer to the accompanying docu­ment XA_005 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 permit-

ted 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.

3.2.3 Operation with inline temperature sensor, type FS2xx0 / FS3xx0

The inline temperature sensor is integrated in the pipe and the entire surface of the inner
pipe wall acts as a temperature sensor. The measurement is all the more precise, the low­er the viscosity of the process media. Insulate the measuring point to the ambient tem­perature to ensure the measuring result is not affected.

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 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.

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.
