Optical measurements using Wedgewood Analytical Brand Products

Endress+Hauser's Wedgewood Analytical brand products are the pioneering leader in the field of optical sensor technology. Available in many configurations our products meet a wide variety of industrial specifications including explosion-proof, sanitary, and high temperature requirements. Our optical instruments consist of a sensor housing, monitor, the interconnecting cables and if required, a monitor enclosure. The sensor consists of a light source and one or more detectors to monitor changes in the light caused by the measured material. Wedgewood Analytical brand products can be supplied in many configurations to meet demanding applications.

• Bubble detection

The Model 611 and AF13 bubble detection system is a special application of the absorbance monitors. The flowcell was designed with modified optics that include a slanted 45-degree window on the lamp assembly of the flowcell. This slanted window allows the detection of empty pipe conditions. It also utilizes a 950nm optical filter to detect liquid phase variations such as alcohol/water.

Bubble detector transmitter OUM611

Bubble detector sensor OUSAF13

This analyzer is used with a Model OUSAF13 sensor for the detection of bubbles in process liquids and is capable to operate under either AC or DC power conditions

• Turbidity and total suspended solids

Turbidimeters measure the ability of undissolved particles in a process sample to scatter light. In other words, turbidimeters measure the clarity of a liquid. As the number of particles in a sample increases, more light gets

scattered and the turbidity increases.

Turbidity monitor model 670

Flow through low turbidity sensor TF10

The Model 670 turbidity monitor is used with a Model TF10 flow through sensor to measure low levels of non-dissolved solids, emulsions, or immiscible fluids in process liquids.

Get more information (PDF 226,0 kB)

This ultra-hygienic low turbidity sensor accurately measures particulates up to the equivalent of 200 ppm. It has optional VIS blocking filters to eliminate color related measurement errors and also a patented window wiping system that prevents process buildup on the optical windows.

• Color analysis

The Model OUM 980 and AF22 color system contains a dual beam photometer for measuring color absorbance in process liquids.

Dual beam photometer model OUM980

Flow through optical sensors OUSAF21 or OUSAF22

Microprocessor based monitor for use in applications to measure color and concentration.

Get more information (PDF 264,0 kB)

These flow through optical sensors are used with a Model 980 analyzer to measure color absorbance. The ultra hygienic CIP and SIP flow cell design attains the highest level of cleanability. This system uses the patented EasyCal™ solution for quick and simple online calibration.
