General Description
The LT2020-ST
Laser Distance Meter operates over a substantial range off static or
passing product in difficult areas in harsh environments. The LT2020-ST
measures distances over a working range up to 30 meters off of natural
surfaces , up to 100 meters off of white surfaces and up to 150 meters
off of a special reflector. For operation with automated positioning
control of material handling transport systems a white reflective target
is used or the special reflector is used. The LT2020-ST can provide a
measuring rate as low as 20 milliseconds when used with a white target
or special reflector target.
Especially suited for precise detection and measurement of cold/hot
product at temperatures up to 600°C
(1112°F). For higher product temperature a
Model LT2000-HT is available for measurement of cold/hot product at
product temperatures up to 1200°C
(2192°F).
Straightforward alignment is easily accomplished via the visible red
laser measuring beam.
Accuracy is +/- 2mm to +/- 5mm according to ambient temperature and
surface reflectivity. Repeatability is +/- 0.5mm and the user scalable
resolution is 0.1mm.
The zero offset and the span of the 4 - 20 mA analog output are both
user programmable. The distance offset is also user programmable, this
allows the user to define a zero point independent of the analog output
zero offset.
Provided with a user programmable digital switching output which is
triggered by exceeding in the positive or negative direction a user
programmable distance threshold. The hysteresis of the digital switching
output is also programmable.
This Robust Laser Distance Meter with built-in air coolant chamber
venting as air purge. Standard operating temperature without air cooling
is 50°C and with air cooling is 60°C. Optional water cooling is
available for an operating temperature up to 70°C.
The LT2020-ST Laser Distance Meter provides a highly accurate
measurement reading. It is ideal for length and width determination, and
checking position of product in and around furnace areas.
Supplied as standard with a switch selectable RS232 & RS422 serial
interface with a 2400 to 38,400 Baud Rate & a programmable 4 - 20 mA 16
BIT analog output. An optional ProfiBus DP Gateway Interface Box is
available. ProfiBus DP, DeviceNet and Ethernet Interface Options will
soon be available. |
