UVS

Stealth-UV

The SMARTEYE® Stealth-UV Analog/ Digital Sensor is a special-purpose sensor designed to detect the presence of invisible UV fluorescent materials contained in special chalk, ink, paint, grease, glue, and optical brighteners found in labels, paper, tape, string, etc. The sensor contains an ultraviolet (UV) solid-state light source that is used to excite the luminescent materials to fluoresce in the visible range. The sensor’s detector then responds to the visible fluorescing light. When the received fluorescing light level changes the analog output responds accordingly to the changes. There are four autoset modes used to scale the analog output as well as set the digital threshold.

CONTRAST INDICATOR
Provides “at-a-glance” performance data, both statically and dynamically.
All 8 LEDs will flash three times if contrast is too low in Two-Point AUTOSET mode.

AUTOMATIC GAIN SELECT
This unique feature provides automatic digital selection of amplifier gain based upon your sensing requirements.

FOUR AUTOSET ADJUSTMENT MODES

  • Light State AUTOSET is the default setting and should be used when performing a setup with the luminescent material in view. 
  • Dark State AUTOSET should be used when setting up on the background, or non-luminescent material. This setting provides for maximum sensitivity when the background is clear of all luminescent material. 
  • Mid-Point AUTOSET should be used when determining the exact amount of luminescent material that is optimal. Sensor then responds to any amount of luminescent material that is too much or too little compared to the optimal amount. 
  • Two-Point AUTOSET should be used when there are two luminescent materials that require contrast deviation. For instance, the background may be a white envelope with luminescent material and the target is the luminescent glue on the envelope.

For more information about modes see below.

ANALOG OUTPUT
The Analog Output is 4-20mA as the standard factory default configuration. The sensor can also be ordered with a 0-5 or a 0-10 VDC output. This provides flexibility when interfacing to different machine input requirements.

MANUAL ADJUSTMENT
The AUTOSET (DWN/↓) and SELECT (UP/↑) button also provide tweaking capability for fine tuning. Simply tap the (DWN/↓) button or (UP/↑) button for small, incremental changes.

TIMER
When the “OFF” delay pulse stretcher is enabled, the output duration is extended by 15 milliseconds. Enabling the Timer allows ample time for the controller to respond to short duration input events.

RESPONSE TIME

  • 200µs for UVS-1A thru 4A
  • 750µs for UVS-5A
  • 300µs for UVS-6A

 
LT/DK OUTPUT SELECT

AUTOSET MODES

Light State AUTOSET ModeA. Light State AUTOSET Mode – With luminescent target in view, the sensor samples the signal level from the target and sets the switching threshold just below that signal level. The sensor is sensitive to less luminescent materials in this mode. This is the default mode and is useful in solving most common applications. The analog output can be used to provide feedback of target brightness level for control applications.

Dark State AUTOSET ModeB. Dark State AUTOSET Mode – With background in view, the sensor samples the signal level from the background and sets the switching threshold just above that signal level. The sensor is sensitive to more luminescent materials in this mode. This mode is useful in solving many common applications. The analog output can be used to provide feedback of target brightness level for control applications in this mode as well.

Mid-Point AUTOSET ModeC. Mid-Point AUTOSET Mode – This mode is recommended for use in analog output applications only. With the luminescent material in view, the sensor samples the signal level from the target and sets the sensor at the switching threshold. The sensor’s analog output then reflects the level of fluorescence as compared to the target…either higher or lower than the sampled signal level. This can be used as part of a feedback loop to maintain or control the flow of materials at an optimum level.

Two-Point AUTOSET ModeD. Two-Point AUTOSET Mode – Use this mode to establish upper and lower limits. When monitoring the target luminescence using the analog output, this mode will set your upper and lower control limits at specific points on the analog output scale. This is the most sensitive mode for detection of low contrast differences in two UV luminescent materials. An example would be glue on a white paper envelope, where both the glue and the paper have optical brighteners present.
