1 Basic safety instructions
Intended use
The CompactPowerMonitor CPM is exclusively intended for measurements which are carried out in or nearby the optical path of high power lasers. Please mind and adhere to the specifications and limit values given
in chapter 18 „Technical data“ on page 48. Other forms of usage are improper. The information contained
in this operating manual must be strictly observed to ensure proper use of the device.
Using the device for unspecified use is strictly prohibited by the manufacturer. By usage other than intended
the device can be damaged or destroyed. This poses an increased health hazard up to fatal injuries. When
operating the device, it must be ensured that there are no potential hazards to human health.
The device itself does not emit any laser radiation. During the measurement, however, the laser beam is
guided onto the device which causes reflected radiation (laser class 4). That is why the applying safety regulations are to be observed and necessary protective measures need to be taken.
In measuring mode, the laser control’s safety interlock must be connected with the device.
Observing applicable safety regulations
Please observe valid national and international safety regulations as stipulated in ISO/CEN/TR standards as
well as in the IEC-60825-1 regulation, in ANSI Z 136 “Laser Safety Standards” and ANSI Z 136.1 “Safe Use
of Lasers”, published by the American National Standards Institute, and additional publications, such as the
“Laser Safety Basics”, the “LIA Laser Safety Guide”, the “Guide for the Selection of Laser Eye Protection”
and the “Laser Safety Bulletin”, published by the Laser Institute of America, as well as the “Guide of Control
of Laser Hazards” by ACGIH.
Necessary safety measures
If people are present within the danger zone of visible or invisible laser radiation, for example near laser
systems that are only partly covered, open beam guidance systems, or laser processing areas, the following
safety measures must be implemented:
• Connect the laser control’s safety interlock to the device. Check that the safety interlock will switch off the
laser properly in case of error.
• Please wear safety goggles adapted to the power, power density, laser wave length and operating mode
of the laser beam source in use.
• Depending on the laser source, it may be necessary to wear suitable protective clothing or protective
gloves.
• Protect yourself from direct laser radiation, scattered radiation, and beams generated from laser radiation
(by using appropriate shielding walls, for example, or by weakening the radiation to a harmless level).
• Use beam guidance or beam absorber elements that do not emit any hazardous substances when they
come in to contact with laser radiation and that can withstand the beam sufficiently.
• Install safety switches and/or emergency safety mechanisms that enable immediate closure of the laser
shutter.
• Ensure that the device is mounted securely to prevent any movement of the device relative to the beam
axis and thus reduce the risk of scattered radiation. This in the only way to ensure optimum performance
during the measurement.
Employing qualified personnel
The device may only be operated by qualified personnel. The qualified personnel must have been instructed
in the installation and operation of the device and must have a basic understanding of working with highpower lasers, beam guiding systems and focusing units.
Conversions and modifications
The device must not be modified, neither constructionally nor safety-related, without our explicit permission.
The device must not be opened e.g. to carry out unauthorized repairs. Modifications of any kind will result in
the exclusion of our liability for resulting damages.

5 Introduction
5.1 System description
The CompactPowerMonitor CPM is a measuring device for the determination of the laser power of laser
beams in the multikilowatt range. The main field of application is the control of laser powers of CO2 or solidstate lasers as well as high power diode lasers available at the work piece. The device is able to measure
both collimated and divergent beams.
5.2 Measuring principle
The CompactPowerMonitor CPM measures the laser power according to a calorimetric principle. The irradiated laser power is absorbed by a water-cooled absorber inside the device. By measuring the cooling water
flow rate and the respective temperature difference between the inflowing and the outflowing water, the
absorbed power is determined.

NOTICE
Damage/Destruction of the device due to different chemical potentials
CompactPowerMonitor CPM
The parts of the device which get in contact with cooling water consist of copper, brass or
stainless steel. Connecting the unit to a colling curcuit containing aluminum components
may cause corrosion of the aluminum due to the different chemical potentials.
Do not connect the device on a cooling circuit in which aluminum components are installed.
X
• The device can be operated with tap water as well as demineralized water.
• Do not operate the device on a cooling circuit containing additives such as anti-freeze.
• Do not operate the device on a cooling circuit in which aluminum components are installed. Especially when
it comes to the operation with high powers and power densities, it may otherwise lead to corrosion in the
cooling circuit. In the long term, this reduces the efficiency of the cooling circuit.
• Should the cooling fail, the device can withstand the laser radiation for a few seconds. In this case, please
check the device as well as the water connections for damages.
• Large dirt particles or teflon tape may block internal cooling circuits. Therefore, please thoroughly rinse the
system before connecting it.
An operation with strongly deionized water (DI-water, conductivity < 30µS/cm) is only possible with
the respective connection parts – we would be glad to advise you as necessary.
8.2 Water pressure

8.4 Temperature fluctuations of the inflowing cooling water
It is important that the temperature of the inflowing water remains constant. The fluctuation of temperature
should not exceed 0.5 ° C per minute or 0.05 ° C per 5 seconds.
8.5 Flow rate
The safety interlock is unblocked at:
Device type Flow rate in l/min
CPM F-1 0.5
CPM F-10, CPM C-9 4
CPM F-20 8
CPM F-30 15
Tab. 8.3: Minimum flow rate
The highest measurement accuracy is reached at a typical flow rate of:
Device type Flow rate in l/min
CPM F-1 1.5 – 2
CPM F-10, CPM C-9 8 – 11
CPM F-20 15 – 22
CPM F-30 25 – 35
Tab. 8.4: Recommended flow rate
For the maximum laser power in case of a fixed flow rate the following rule is applicable:
Flow rate multiplied by 1.4 = maximum laser power. For 5 l/min this equals about 7 kW.
This calculation serves to prevent a possible overload.
Typical flow rates and temperature rises for the highest measurement accuracy can be found in Tab. 8.5 on
page22.

20 Appendix
20.1 Operation of the CompactPowerMonitor with PanelDisplay (without PC)
By option there is a external control display (PanelDisplay, Order-No. 130-005-003) available for the operation of the system. The display is operated via the standard PRIMES bus and therefore enables the reading
from a greater distance from the measuring position without a PC.
1. Please connect the display and the CPM by the 9-pole D-Sub cable for the PRIMES RS485 bus (on the
front or on the rear side).
2. Connect the power supply unit via the adapter to the 9pin D-Sub socket (RS485) of the PanelDisplay.

Display Meaning
W Laser power in W
Flow Water flow rate in l/min
Te Water temperature at the entrance in °C
Td Temperature difference between water input and output in
Tab. 20.2: Meaning of the measured display
Kelvin (a temperature difference of 1K corresponds to a temperature difference of 1°C).
For the operation with the PowerMonitorSoftware via PC, you have to change the operating mode
of the display from “Active” to “Passive”. Further information can be found in the operating manual
„Panel Display“, chapter „Operating Mode“.

20.2 Mounting position of a CompactPowerMonitor CPM with oval wheel meter
Please note during installation, that the axis of the oval wheel meter must always be horizontal.
Oval wheel meter axis
Fig. 20.2: Position of the oval wheel meter axis
Correct mounting position
The device can either stand on its
feet (A) or the connections and display are in an upright position (B)
Incorrect mounting position
The flat side of the oval wheel
meter must not point downwards
(to the table).
A B
Tab. 20.3: Mounting position of the CompactPowerMonitor CPM with oval wheel meter
Revision 02/2019 EN
For a continuous operation, the oval wheel meter axis has to be positioned horizontally. For a short
period of time (a few hours per year) the CPM with oval wheel meter can be operated in the “incorrect“ installation position without immediately causing damages to the device. Longer operation
periods, however, may wear off the flow rate sensor.
