1 Introduction
Thank you for purchasing a PCE-IR 5 from PCE Instruments.
The PCE-IR 5 gives you the possibility to measure the surface temperature of objects without contact.
The most important advantage of an infrared thermometer is that you can measure areas that are
normally hard to access, as well as moving parts. The temperature sensor, the electronics and the optical
system are protected by the metal case of the PCE-IR 5. The infrared thermometer is easy to assemble
and the measuring unit can easily be connected to the installation equipment. Moreover, you can upgrade
the PCE-IR 5, e. g. by adding a protective ring or by making it possible to mount the thermometer in a
three-dimensional 90 ° angle. This will cover all requirements for working under various conditions.
2 Safety notes
Please read this manual carefully and completely before you use the device for the first time. The device
may only be used by qualified personnel and repaired by PCE Instruments personnel. There is no
warranty of damages or injuries caused by non-observance of the manual.

5 Information and instructions
5.1 Infrared measuring principle
Infrared thermometers measure temperatures of objects without contact. The surface temperature is
measured on the basis of the emitted infrared intensity. The fact that the measurement can be carried out
without contact is the most important advantage of an infrared thermometer. Thus, the user can quickly
and easily make measurements in areas which are normally hard to access or measure moving objects.
5.2 Delivery content
Standard package: 1 x PCE-IR5 (1.8 m cable)
Directly on receipt of your goods, please inspect both the packaging and the device itself for any signs of
damage. If so, contact the seller immediately. Keep the damaged packaging.
The serial number of the product can be found on the sticker which you can find on the product. Please
have it ready when contacting the customer service.
5.3 Installation
The PCE-IR5 can be installed by means of the installation equipment and aligned accordingly.
Cabling in current loop
Red
24 VDC positive
Black
24 VDC negative
Colourless wire
Protective earth conductor
Output: 4 … 20 mA linear signal, 0.032 mA/°C
5.4 Electronic interference
To avoid disturbances due to electromagnetic fields during the measurement, please note the following:
Do not install the infrared thermometer within the close proximity of electric motors, heavy-duty cables,
etc. Consider using the protective ring. The probe head protection must be correctly grounded.
5.5 Measuring dimensions
When using the infrared thermometer at a distance from the object of 20 mm, the measuring spot will be
1 mm. The measuring spot will increase when the thermometer is farther away from the object to be
measured. When the distance is 200 mm, the measuring spot will have a diameter of 10 mm. The ratio
between the distance from the thermometer to the object and the size of the measuring spot is the optical
resolution, which is 20:1 in this case.
5.6 Lens cleaning
To make sure that the measured values are accurate, the infrared thermometer’s lens must always be
kept clean. By doing so, you can avoid faulty measurements, damage of the lens and of the entire device.
In case dust or similar materials are on the lens, soak a cloth in pure alcohol and then use it to clean the
lens.
5.7 Maintenance
If you have any problems using the infrared thermometer or any questions, please contact our customer
service. Our staff members will give you technical advice on the thermometer and its maintenance. Since
the device is very simple, it will normally be possible to solve your problems via telephone, which will
make it unnecessary to send the device back.
6 Disposal
For the disposal of batteries, the 2006/66/EC directive of the European Parliament applies. Due to the
contained pollutants, batteries must not be disposed of as household waste. They must be given to
collection points designed for that purpose.
In order to comply with the EU directive 2012/19/EU we take our devices back. We either re-use them or
give them to a recycling company which disposes of the devices in line with law.
If you have any questions, please contact PCE Instruments.
