Teledyne has introduced a family of
fiber optic based photometric transmitters that are application specific, simple
to use, and cost effective. Based on significant experience in the design and
manufacturing of photometric instruments, the Photo-X series now offers the
industry a customized build your own approach to on-line, UV-VIS or NIR
applications.
Photometric Transmitter
The photometric transmitter can be
manufactured according to a specific application requirement. Through our build
your own program, the client can customize the components that are integrated
into the transmitter. Customers now have options to select from in a menu style
ordering guide to construct their personalized Photo-X.
The menu includes:
Lamps:
To cover all application regions of
the spectrum, we offer both internal and external lamps. Internal lamps can be
packaged along with the Photo-X.
Detectors:
To have sensitivity in the region of
interest, Teledyne can match the spectral output of the lamp with the most
efficient detector for the intended application. Detectors used are PMT, Si,
InGaAs, and PbS.
Packaging:
Through our systems integration
group, we can package the transmitter for general purpose and hazardous
environments.
Fiber Optic
Accessories:
Safely interfacing to a process
stream is a very important consideration when monitoring in industrial
environments. Teledyne can offer extractive fiber optic flow cells that range in
path length from 0.02 mm to over a meter in length, and in-situ probes that can
take pressures up to 10,000 psig and temperatures up to 3150C.
Window Fouling
Circuit:
The Photo-X series provides a local
indication that the windows are fouling. The local LED lights up when the
reference signal has deviated by a customer established set point.
Calibration:
All Photo-X products can be supplied
with an optional automatic / manual span filter that attenuates the measuring
beam by a fixed amount every time it is introduced. This method is called
calibration by standard addition and employs a reference filter (NBS or NIST
traceable) to give a reproducible response when the filter is placed into the
measuring beam.
Outputs:
Scalable 4-20mA, local digital
display, and local indication of instrument status are common outputs for all
Photo-X transmitters.
