Thermal Imager Fluke thermal imagers

Using the Fluke thermal imagers means you have easy access to the powerful diagnostic and predictive functions of infrared thermography, to safely track potential problems. Immediately and without making contact, detailed temperature images are shown for rapid detection of hotspots.

Temperature range: -20°C up to 1200°C.

Gross prices Fluke thermal imagers start at € 2.245,-.

Raytek and Ircon infrared themometers

We can measure temperatures without making contact by using heat radiation (infrared) of an object.

The measured intensity of the radiation is being transformed by a thermometer to a temperature. Sometimes non contact measurement is not possible or special provisions are required.

We would be pleased to inform you about the possibilities.

Temperature range: -50°C up to 3500°C.

Raytek is market leader in several branches when it concerns infrared measurements.

Portable IR Raytek infrared themometers

We can measure temperatures without making contact by using heat radiation (infrared) of an object. B.L.W. Visser portable infrared thermometers B.L.W. Visser knows temperature, thanks to over 30 years of experience in the field of (infrared) thermometers.

We now offer you the latest on non contact infrared thermometers, probes, accessories, and expertise on all areas. Besides that B.L.W. Visser also supports all instruments with the best guarantee in its branch with our own calibration laboratory for infrared thermometers.

Temperature range: -50°C up to 3000°C. Gross Prices start at € 90,-.
EP / Scangrip leak detectives

We have known it for a long time : compressed air leakages are expensive! One leak of approximately 2 mm means a yearly loss of approximately 15 m³ per hour. At a price of 7 cent per cubic meter approximately € 2.000,- per year!

An EP leak detector sometimes recovers your costs within one week! Even steam trap leakages are easy to detect.

Not only for compressed air but also the cooling and vacuum technology EP will be your ideal leak detector.
BetalaserMike

Non-contact measurement of length and/or speed with a minimum of 0,05% accuracy (permanently calibrated). The BetalaserMike systems can effortless replace any encoder regardless of the requested pulse outputs.

Speed range: 0 to 20.000 m/min.

SM500 Hyde Park ultrasonic sensors

Non-contact detection without restrictions on the object or material.

Ultrasonic sensors and level detection equipment. In dual-level or analogue version. For detection of glass, metal, powders, liquids etc. Unaffected by humidity and filthiness. Protection rating IP67! Available for a.o. monitoring of pumps or detection of pots, cans, bottles and foil.

Liebherr Moisture measuring

Pleva and Liebherr online measurement and control equipment for among other things moisture, (coating) application.
FMSII
betacontrol Thickness measurement and surface control

Our systems guard and monitor your production range of lane-shaped materials. During production you will receive all the necessary information on quality, such as structure faults, surface weight, thickness, layer thickness, density and moisture. With the supplied software the data can be logically and easily processed in your process control system. Deviations of pre-set limits can be corrected independently by our systems. As you are used of most of B.L.W. Vissers measuring systems, these systems are also non-contact. We work with the systems of Lase, Betacontrol, Shelton Vision, Jenoptik etc.
Powertrol

Flare monitoring for the petro chemical industry. Complete control over your flare installation by using the Powertrol infrared systems. Powertrol guards your burner and flame from a distance which makes it a maintenance free monitoring system. On/off control and gas control on the flare and prevention of a sooty flame by steam injection. Completely monitored by the Powertrol installation. Used in several places in the Benelux!!
Non-contact specialities
reflex Neoptix

Neoptix is known worldwide for measuring temperature in places where conventional sensors fail. The fiber optic probes are insensitive to most chemical and physical influences. MRI scanners, microwave-ovens, high vacuum installations, transformers, or semi-conductor production, nuclear fusion, these are all applications where Neoptix is used as temperature control system.

Lamerholm Shocklog Recorders

The Shock log recorder is a programmable system that registers 3 dimensional shocks. This means that the RD298 guards your product registering the shocks of the X, Y and Z axis.

Retrospectively, the RD298 gives you a very accurate analysis of what happened to your machines, systems, art, glass etc. during transport. In case of negligence, falling, bumping, storm, etc. during transport, the RD298 will have made an accurate record of it. The most important possibilities of the shock loggers are: registration when the shock occurred and from which direction, during several months!

Tracking the complete transport over a long period and support when insurance disputes occur.
