LLT100

Laser level transmitter

Quick start instructions for

LLT100 laser level transmitter

Measurement made easy

Introduction

The LLT100 is a high performance laser level

transmitter that accurately measures level, distance,

and position over long ranges in industrial

environments. The LLT100, using an eye-safe pulsed

laser beam, features advanced timing and

sophisticated signal processing for pinpoint

accuracy.

Features

• Range up to: 100 m (330 ft) for level of solids /

30 m (100 ft) for level of liquids / 200 m (660 ft)

for positioning applications

• Narrow, easy-to-aim laser beam

• Measures solid surface even at wide angles

• Measures liquid levels even for clear liquids

• Robust aluminum or stainless steel enclosure

• Easy and intuitive setup / no calibration required

• Explosion proof class 1 / division 1 (zone 1)

• 2-wire power from the 4 to 20 mA loop

• HART communication

• Embedded HMI / Display

1 Health & Safety

WARNING

Bodily injury

Read the LLT100 Operating Instruction OI/LLT100 - EN

carefully before working with the product.

For personal and system safety, and for optimum

performance, make sure that you thoroughly understand

the contents before installing, using or maintaining this

instrument.

NOTICE

• All servicing of the equipment is to be performed at

factory by qualified service personnel only.

• No user / operator adjustments inside the LLT100 level

transmitter are recommended by the manufacturer.

3 Mounting

Install away from falling

material for easiest

configuration

For solids laser beam can

be aimed at any angle

Also typically applies to other

scattering surfaces such as

slurries and some turbulent

liquids

For typical liquid applications

laser beam must be as

perpendicular as possible,

not exceeding 90° ± 5° to

the surface

4 Easy setup

1 Rotate the housing: unscrew the stop tang-screw by

approximately 1 rotation (do not pull it out) before removing

the housing. When the desired position is reached,

re-tighten the stop tang-screw.

2 Connect the cables (15.5 to 42 V DC) to the LLT100 laser level

transmitter – if using HART the minimum input voltage is

21 V DC.

3 Power on the transmitter.

4 Press the Right arrow key ( ) on the display and select your

access level using the Up and Down arrow keys ( ).

5 Set the main parameters at the Easy Setup menu:

a Select the required language.

b Select the measurement mode:

standard, clear liquid, positioning or dust/vapor.

c Enter the vessel height (URP).

d Set the sensor offset from the vessel top.

e Select the primary variable (PV) for the 4 to 20 mA output:

level, ullage, volume.

f Choose the unit of the primary variable (PV):

m, cm, mm, ft.

g Set the value for vessel empty (LRV).

h Set the value for vessel full (URV).

i Enable or disable the filling rate.

j Enter the Tag name.

6 Once the settings are completed, press Exit to return to the

Distance view.

Refer to Operating Instruction OI/LLT100 -EN for detailed

configuration / setup information.
