Lab equipment

Below an overview of the available lab equipment in the Kleinhorst Laboratory can be found. 


Hot-Wire anemometry

The device available in the lab is a DANTEC StreamLine controller (90N10) with a DANTEC CTA Module (90C10)

Scientific Camers

There are three scientific cameras in the Lab:

  • Redlake MotionScope 1000S
  • Princeton Instruments PI-MAX3
  • Princeton Instruments for Spectrometer

redlake motionscope 100s

Key features are: 

  • Resolution up to 480×420 px
  • Frame rate up to 1000 frame/s
  • Exact resolution depends on the frame rate. See the table below
  • It can be used in combination with the Image Intensifier (HS-IRO)
  • 8 bit resolution
  • Enhanced memory
  • Camera is controlled by PCI card, which means it cannot be used as a standalone camera. It is always accompanied with the PC where the PCI card is installed.
  • Data is stored as uncompressed avi
  • C-mount

Princeton Instruments PI-MAX3

Key features are:

  • Resolution up to 1024×1024
  • Frame rate is dependent on the used resolution, but the camera is optimized for intensity instead of speed. Typically 10-20 Hz @ 1024×1024 is possible
  • 8 bit resolution
  • Build in Intensifier (GEN2 SB)
  • Controlled via gigabit-ethernet connection with LightField
  • Data is stored in Spe-format (Can be read with matlab using SpeReader.m )
  • F-mount

Princeton Instruments for Spectrometer

This intensified camera is usually used in combination with the spectrometer.


To increase the sensitivity of the camera the intensifier can be used. See for an explanation of the operating principle http://en.wikipedia.org/wiki/Image_intensifier. It is equiped with a 2nd generation SB Photocathode, which has a high sensitivity in the UV range.

The image intensifier makes it possible to obtain images with short exposure times. Down to 40 ns (in the case of OH-LIF) is possible. The timing of the intensifier is controlled by a separate High Voltage controller, hows timing settings should be synchronized with that of the camera.

Photomultiplier Tube

A photomultiplier tube (PMT) is an extremely sensitive and fast light sensor. It can detect light in the range from UV to near infrared of electromagnetic spectrum. See for more details http://en.wikipedia.org/wiki/Photomultiplier

In the Kleinhorst a PMT is usually used togheter with an optical filter to investigate the high frequency behavior of flames that emit light with specific wavelengths (chemiluminescence).

Pressure sensors

Several types of pressure sensors are in use in our laboratory:

Position sensors

The Heidenhain Positip 850 is available in the lab for tracking the position of objects moving slowly along straight lines, for example in traverse systems. The Positip 850 system consists of a number of linear encoders of various sizes and a monitor showing the current positions. Up to 4 encoders can be connected to the monitor to keep track of the object position with an accuracy of several micrometers, each one for a particular axis of displacement. 

It is possible to send the positions measured by the encoders to a LabVIEW program via a serial connection between a lab PC and the Positip monitor (RS-232 protocol, DB-9 connector).

Gas analyzers

In the lab you will find two cabinets containing gas analyzing equipment. These cabinets, shown in the figure, are used for continuous sampling of a conditioned gas stream, such as flue gases from a combustor or chemical reactor. The one on the left, often called 'IR-cabinet' or 'IR-kast' in Dutch, is equipped with analyzers for measuring concentrations of O2, CO, CO2, SO2, NO and NOx. The one on the right, mostly called 'FTIR', contains a Fourier transform infrared (FTIR) analyzer for measuring a wide range of gas compounds, as well as dedicated analyzers for detecting O2 and total hydrocarbon content. Besides the two analyzer cabinets, a portable gas analyzer is available to determine concentrations of O2, CO and NO on the spot. This device has a built-in conditioner and therefore doesn't have to be connected to the central gas conditioning unit in the lab.
