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.
