•
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 thread sealant with all
installations. Take care not to overtighten the fittings. Always check for
leaks prior to system start-up.
•
Wiring and Electrical: Section 2.0, Specifications and Section 4.0,
Electrical Connections, provide the voltage and current limitations and the
wiring for the various sensor types. The sensor electrical ratings should
never be exceeded. Electrical wiring of the sensor should be performed in
accordance with all applicable national, state and local codes.
•
Pressure and Temperature: Section 2.0, Specifications, provides the
pressure and temperature limits for each model. Operation outside these
limitations will cause damage to the unit and can potentially cause personal
injury.
•
Material Compatibility: Make sure that the model which you have
selected is chemically compatible with the application liquids. While the
meter is liquid and spray resistant when installed properly, it is not
designed to be immersed.
•
Flammable, Explosive and Hazardous Applications: The TDD series is
not an intrinsically safe or explosion proof design. They should not be used
in installations in which an instrinsically safe or explosion proof design is
required.
•
Make a Fail-safe System: Design a fail-safe system that accommodates
the possibility of switch or power failure. In critical applications, KOBOLD
recommends the use of redundant backup systems and alarms in addition
to the primary system.
