Model LT2020-SP Laser Distance
Measurement Meter
|
General Description
The LT2020-SP Laser Distance Meter
operates over a substantial range off static or passing product in
difficult areas in harsh corrosive environments. The LT2020-SP 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-SP can provide a measuring
rate as low as 20 milliseconds.
Especially suited for precise detection and measurement of cold/hot
product at temperatures up to 600°C (1112°F). For higher product temperature our
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.
The LT2020-SP is 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.
The LT2020-SP is a robust Laser Distance Meter and is provided in a NEMA
4 - IP66 Fiber Reinforced Polyester Weather Resistant - Corrosion Proof
Enclosure. Standard operating temperature is 50°C.
The LT2020-SP laser distance meter provides a highly accurate
measurement reading. It is ideal for length, width, thickness, depth,
height, position determination.
The LT2020-SP is supplied a standard with either a RS232 or RS422/RS485
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.
