STANDARD FEATURES
- Measurement of Optical Densities from 0.00 to 4.00
- Selectable sensor sensitivity
- Self calibrating
- Serial interface; reducing the number of wires required, allowing
for variable hosts, and providing for increased noise immunity
- Real time display of Optical Density and real time calculation
and display of metalized film resistance (ohms/sq.) and thickness,
based on corresponding
- Optical Density data
- Optical Density, Resistance, and Thickness data saved at regular
intervals
- Sensing outputs and equivalent measurements are frequency based,
providing for increased noise immunity and digital versatility
Internal control circuitry can be remotely located from the actual
sensor array (up to 10 feet), allowing for mounting flexibility
and space savings
- Flexible. Software upgrades allow for customization with minimal
effort
- Flexibility in sensing array dimensions and number of elements
employed
|
OPTIONAL FEATURES
- Serially programmable in circuit configuration allowing for
variable user defined applications and for in circuit uploading
of selected lookup tables and/or user directives
- Selectable user defined Optical Density window and sensor alarm
when outside of defined range
- Selectable measurement techniques to tailor sensor speed
- Individual sensor selection and corresponding individual run
history graphs
- Interface to existing web counter/web system to correlate Optical
Density with actual position data
- Increased data transmission rates
