​Inline Colour & Concentration Measurement With A DCP007 Process Photometer

The Kemtrak DCP007 is an easy to operate industrial fiber optic photometer designed to accurately measure the concentration and color of process samples. Measurements are real time and in-line.

The Kemtrak DCP007 uses a long life high performance LED light source with robust industrial grade fiber optics to provide drift and noise-free measurement with very high precision.

A proprietary dual wavelength four channel measurement technique and advanced digital electronics design allows deep absorbance measurement to 5 AU. A range of shorter optical pathlengths allow for deeper absorbance measurements. Automatic compensation for sample turbidity and/or fouling of the optical windows ensures trouble free operation.

Maintenance free measurement cells with sapphire windows have no electronics or moving parts making the unit suitable for hazardous area use.

Benefits

  • Real time inline measurement
  • Drift and noise free measurement
  • Down to 5 AU (1 cm OPL), deeper absorbance measurements with shorter path lengths
  • Zero maintenance measurement cells & fibre optics
  • Long life LED light source that is easy to change
  • Analogue output (0/4-20 mA)
  • Modbus (slave) over TCP/IP & Profibus (optional)
  • Local & web based graphical user interface (TCP/IP)
  • ATEX Exd IIB + H2 T6 IP66 Category II 2 G (optional)
How does it work?

The Kemtrak DCP007 colour and concentration analyzer consists of three components:
  1. Control Unit. The control unit contains all electronics including light source and detectors.

  2. Measurement Cell. Robust in-line (flow through) industrial process connection.

  3. Fibre Optics. Industrial grade fibre optic assembly connects the control unit to the flow-cell.

The configuration shown here is a 316L stainless steel DIN DN50 flange measurement cell with stainless steel fully interlocked fibre optic assembly. Both measurement cell and fibres can withstand 250°C (482°F).

Measurement Principle
​The Kemtrak DCP007 photometer measures at two wavelengths. A primary "absorbing" wavelength is used to measure the substance being monitored while a "non absorbing" reference wavelength is used to compensate for turbidity, air bubbles and/or fouling.
Picture
Fiber optics are used to shine a precisely focused light beam through the process medium and back to a silicon photo-detector. A second photo-detector is used directly on the lamps to compensate for temperature effects and aging. The resulting measurements are very accurate with low drift and long-term calibration stability.
The attenuation of the transmitted light beam caused by light absorbing substances in the process medium is mathematically described by the Beer-Lambert law.
Applying the Beer-Lambert law (below), the concentration of the sample can be calculated.
Picture
A = ε l c
 where:
  A=absorbance (= - log transmittance)
  ε=molar absorptivity coefficient
  l=optical path length
  c=concentration of absorbing species
The Kemtrak DCP007 photometer is ideally suited for industrial environments where simplicity, stability and low maintenance is vital.
