Kobold DRG-11 Manual

• User's Responsibility for Safety: KOBOLD manufactures
a wide range of process sensors and technologies. While
each of these technologies are designed to operate in a
wide variety of applications, it is the user's responsibility to
select a technology that is appropriate for the application, to
install it properly, to perform tests of the installed system,
and to maintain all components. The failure to do so could
result in property damage or serious injury.
• Proper Installation and Handling: Use a proper sealant
with all installations. Never overtighten the sensor within its
fittings. Always check for leaks prior to system start-up.
• Wiring and Electrical: This is an electrically operated
device and only properly trained personnel should install
and maintain this product. Be sure that the power supplied
to the sensor is appropriate for the electronics supplied.
Electrical wiring should be performed in accordance with all
applicable national, state and local codes.
• Temperature and Pressure: The DRG is available in
several material combinations. Temperature and pressure
maximums vary depending upon the material selected.
Operation outside these limitations will cause damage to
the unit.

Precautions

• Material Compatibility: The DRG process wetted
parts for the various body materials are stated below.
Make sure that the DRG is chemically compatible with
the application liquids. While the sensor's outer housing
is liquid resistant when installed properly, it is not
designed to be immersed. It should be mounted in such
a way that it does not normally come into contact with
fluid.
• Flammable, Explosive and Hazardous Applications:
The DRG is not an explosion-proof design. It should not
be used in applications where an explosion-proof
design is required.
• Make a Fail-Safe System: Design a fail-safe system
that accommodates the possibility of sensor or power
failure. In critical applications, KOBOLD recommends
the use of redundant backup systems and alarms in
addition to the primary system.
