Model LT2020-XT Laser Distance
Measurement Meter For Explosion Proof Applications
|
General Description
The LT2020-XT Laser Distance Meter
operates over a substantial range off static or passing product in
difficult areas in harsh hazardous and outdoor environments. The
LT2020-XT measures distances over a working range up to 25 meters off of
natural surfaces , up to 85 meters off of white surfaces and up to 125
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-XT 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). .
Straightforward alignment is easily accomplished via the visible red
laser measuring beam.
Accuracy is +/- 3mm 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-XT 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-XT is a robust Laser Distance Meter and is provided in a Sand
Cast Copper Free Aluminum Explosion Proof Housing. The Housing meets
Explosion Proof Certifications for Class I, Groups B, C, D; Class II,
Groups E, F, G; Class III, NEMA 7BCD, NEMA 9EFG and ATEX IIC. The
Housing can also be used in IP66 and NEMA 4X Water Tight Applications.
The Housing has a corrosion Resistant, “Safety Blue” Polyester Powder
Coating and utilizes Stainless Steel Hardware. Standard operating
temperature is 50°C.
The LT2020-XT laser distance meter provides a highly accurate
measurement reading. It is ideal for length, width, thickness, depth,
height, position determination.
The LT2020-XT 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.
