Warranty Service and Repair
About this Manual:
PLEASE READ THE ENTIRE MANUAL PRIOR TO INSTALLING
OR USING THIS PRODUCT. This manual includes information on two
different models of Tuning Fork sensors from Kobold, all in the NWP
series. Please refer to the part number located on the sensor label to verify
the exact model which you have purchased.
User's Responsibility for Safety:
Kobold manufactures a wide range of liquid level sensors and technolo-
gies. While each of these sensors is designed to operate in a wide variety
of applications, it is the user's responsibility to select a sensor model that
is appropriate for the application, install it properly, perform tests of the
installed system, and 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 the fitting, beyond a maximum of 80 inch-pounds torque. Always
check for leaks prior to system start-up.
Material Compatibility:
The NWP series sensor is available in one wetted material
version. The
body
of
the
mo
del
NWP-14
05
is
made of
PP (Polypro
pylene)
with the
forks made
of
PPS
(40%
glass filled).
Make sure
that
the model
which you
have selected
is compatible
with the
application
liquids. To determine the chemical
compatibility between the sensor and
its application liquids, refer to the
Compass Corrosion Guide, available
from Compass Publications (619-589-9636).
Temperature and Pressure:
The NWP series sensor is designed for use in application temperatures
up to 90
°
C, and for use at pressures up to 150 psi @ 25
°
C., derated @
1.667 psi per
°
C. above 25
°
C.
Wiring and Electrical:
The supply voltage used to power the NWP series sensor should never
exceed a maximum of 36 volts DC. Electrical wiring of the sensor should
be performed in accordance with all applicable national, state, and local
codes.
Flammable, Explosive and Hazardous Applications:
The NWP series sensor should not be used within flammable or explo-
sive applications. In hazardous applications, use redundant measure-
ment and control points, each having a different sensing technology.
WARNING
Do not squeeze the forks together. Doing so could
damage or break the sensor and void the warranty.
