Introduction
The LMT Series of level transmitters is a modular range of field
mounted, microprocessor-based electronic transmitters,
utilizing multiple sensor technologies. Accurate and reliable
measurement of liquid levels is provided in even the most
difficult and hazardous industrial environments. The LMT
Series can be configured to provide specific industrial output
signals, according to 4-20 mA with HART digital
communication. The LMT Series consists of two models:
LMT100 (insertion-mounted) and LMT200 (mounted on gauge
(KM26).
Standard Precautions
CAUTION
Only qualified and authorized personnel are to be tasked
with the installation, electrical connection, commissioning
and maintenance of the transmitter. Qualified personnel are
those individuals who have experience in the installation,
electrical connection, commissioning and operation of the
transmitter or similar devices and hold the necessary
qualifications. These qualifications include but not limited
to:
• Training or instruction – authorization to operate and
maintain devices or systems according to safety
engineering standards for electrical circuits, high
pressures and aggressive media
• Training or instruction in accordance with safety
engineering standards regarding maintenance and use of
adequate safety systems.
Since the transmitter may form a link within a safety chain,
it is recommended that the device be replaced immediately
if defects are detected. In the event of use in a hazardous
area, only non-sparking tools are to be used.
IMPORTANT NOTE
Read the LMT Series operating instructions carefully before
working with the product. For personal and system safety and
for optimum performance, make sure you thoroughly
understand the contents before installing, using or maintaining
this instrument.
