| HPQ-T
PIPE MOUNTED, SELF-CONTAINED LIQUID SENSOR [Click
the picture for pdf file] |
|
 The
HPQ-T sensor is designed specifically for liquid level detection
by non-contact methods in clear or very translucent pipes.
The sensor is mounted on a pipe that is between 3 to 7mm or
8 to 13mm in diameter and features an infrared light beam
that becomes refracted and undetectable by the receiver when
the liquid is present. The device runs on 10-28 VDC, has a
response time of 2 msec max, has Light Operate/ Dark Operate
Selectable output functioning, and has a 100 mA NPN or PNP
output. There is minimal malfunction when air bubbles or water
droplets are present. The indicator light is easy to view
even when the sensors are gang mounted as all the controls
and adjustments are located on the back side.
| Features and
Benefits |
- Small compact size and non-invasive sensing
make installation and height adjustment easy
- Many products to select from - provides flexibility
to user based on concerns
- Thru scan principle where liquid refracts light
beam - insures reliable detection
- Infrared beam can help penetrate slurries and other
solids with similar detection
effect as water/liquid. This can be used in mixing
sections of the process.
- Light operate / dark operate selector switch provides
output flexibility.
- Indicator lamp is easy to view even when sensors
are gang mounted

 These
fiber cables are used exclusively for liquid level detection
in chemical baths, cleaning baths, and spin coaters/developers.
The liquid surface is detected by contact of the sensor tip
with the liquid surface. The proprietary tip structure prevents
liquid buildup so stable detection is maintained. Their bend
radius is less than all known competitors at 30 or 40mm and
they have an operating temperature range of -30 to 105 degree
C. Cable length is 2 meters.
