GENERAL
MP102
LIQUID LEVEL SENSOR
 Micron's
Model MP102 is a small diameter high-stability (water/liquid level)
pressure transducer with an integral 4 to 20 mA signal conditioner
to automatically compensate for line resistance and power supply
fluctuations. The sensor utilizes high reliability bulk type semiconductor
strain gages which are bonded directly to the inside surface of
a machined diaphragm. The transducer and electronics package are
housed in corrosive resistant titanium (6AL4V) body.
With a diameter of only
0.375 inches, the MP102 can easily be installed into holes with
diameters as small as 0.5 inch. Transducers are available with cable
length up to 1000 feet; with splicing, greater lengths are possible.
Please consult the factory for non-standard pressure ranges.
This product is available
with an internal hermetic seal which dramatically increases reliability
and accuracy. At the cable exit, titanium armor is provided to improve
the cable pull strength while maintaining a water seal. A moisture
insulator located near the end of the cable is available and eliminates
inter-conductor condensation. All cables are double-jacketed for
extra protection.
