1.0: Introduction
1.0: Introduction
Solartron Metrology’s Class 2 visible laser gauge sensor combined with Solartron’s Orbit
and Orbit ACS products offers a solid non contact metrology solution for many applications.
1.1 OPTICAL TRIANGULATION
The design of the LT sensor is
based on optical triangulation. An
emitter transmits a visible laser
light beam towards a target. The
light beam bounces off the target
scattering light some of which
reaches the LT sensor detector. The
position of the light on the sensor
is directly related to the position of
the target. The LT sensor processes
this data and provides a signal that
is passed to the Orbit ACS or Orbit
module.

2.0: Laser Warnings and Laser Class 2
Safety Notes
2.0: Laser Warnings
DO NOT look directly at the laser beam with the naked eye or any form of
optical equipment.
DO NOT point the laser at a persons eye at close range
Beam Paths
The beam emitted by the laser sensor should be terminated at the end of
its useful path. Open laser beams should be located above or below eye
level.
CAUTION This product contains NO USER SERVICEABLE PARTS do not
attempt to repair

3.0: Setting the LT Optimum Measuring
Position
3.0: Setting the LT Optimum
Measuring Position
The optimum measuring position
for the LT sensor is a distance
of 49 mm to 51 mm from the LT
sensor face to the target. Best
results are obtained after allowing
a 20 minute warm up period.
Unless requested otherwise the
LT sensor will be shipped set up
with a measuring range of 10
mm with the 5 mm position set
at 50 mm from the target. This
optimizes the measurement at
5 mm ±1 mm.

4.0: Control Buttons
The laser speed can be adjusted to
450 Hz, 45 Hz or 4.5 Hz. The lower
the speed, the better the performance.
The laser will be supplied set to 4.5
Hz. Pressing the speed button will
change the speed, the FAST and
SLOW indicator lights show the
current speed
The Teach Button is used to set the
LT range.
The Signal LED shows the quality of
the received signal from the target.

5.0: Setting the LT Range
5.0: Setting the LT Range
The LT Sensor range is set using the sensor keypad, this may be required to calibrate the
laser against different surfaces. The range can be adjusted using the following sequence.
5.1 SET THE 0 MM POSITION (FURTHEST FROM THE SENSOR)
Set the target to the required 0 mm position ensure that this is no further than 60 mm from
the LT sensor face. Press the red analogue programming button for 2 seconds. The red
Teach led will turn on. Press the same button for a second time. The red Teach led will
flash at 2 Hz, this indicates the 0 mm position has been set.
5.2 SET THE FULL RANGE MM POSITION (CLOSEST TO THE SENSOR)
Adjust the target to the full range position. Ensure that this is not closer than 45 mm from
the LT sensor face. Press the red analogue programming button, the red led will go
off indicating that the full range position has been set. The sensor will return to normal
operation.
Note: Ensure that the Orbit ACS is set to the same range as the laser using the Scale
Configuration Function in the Orbit ACS Configuration Menu.
Note: Ensure that any software using the Orbit library can accommodate the scale
changes. As the output from the Orbit module will be 0 to MaxCount in all cases. (Max
count = 16384 for 14 bit resolution, 65536 for 16 bit and 262144 for 18 bit).

6.0: Laser Beam Control
6.0: Laser Beam Control
The laser beam can be switched off, allowing lasers to measure points very close together
where the beams may interfere if both beams were on. In the Beam off mode the laser
head is still powered which keeps the laser operating at full specification so that readings
can be taken quickly following turning the beam on. Beam Control is via the Orbit3
interface, the Orbit ACS menu or Modbus commands.
