4. Cleaning
1) Since the pressure sensor chip is
exposed to the atmosphere, do not allow
cleaning fluid to enter inside.
2) Avoid ultrasonic cleaning since this
may cause breaks or disconnections in
the wiring.
5. Environment
1) Please avoid using or storing the
pressure sensor chip in a place exposed
to corrosive gases (such as the gases
given off by organic solvents, sulfurous
acid gas, hydrogen sulfides, etc.) which
will adversely affect the performance of
the pressure sensor chip.
2) To ensure resistance to power supply
superimposed noise, you must provide a
capacitor at the power supply input
terminal of the sensor in order to stabilize
the power supply voltage. We recommend
to provide 0.1 µF and 1,000 pF capacitor
in parallel. Please confirm the noise
resistance with the actual equipment and
choose adequate capacitor.
3) Since the internal circuitry may be
destroyed if an external surge voltages is
supplied, provide an element which will
absorb the surges.
4) Malfunctioning may occur if the product
is in the vicinity of electrical noise such as
that from static electricity, lightning, a
broadcasting station, an amateur radio, or
a mobile phone.
5) Since this pressure sensor chip does
not have a water-proof construction,
please do not use the sensor in a location
where it may be sprayed with water, etc.
6) Avoid using the pressure sensors chip
in an environment where condensation
may form.
Furthermore, its output may fluctuate if
any moisture adhering to it freezes.
7) The pressure sensor chip is
constructed in such a way that its output
will fluctuate when it is exposed to light.
Especially when pressure is to be applied
by means of a transparent tube, take
steps to prevent the pressure sensor chip
from being exposed to light.
8) Avoid using the pressure sensor chip
where it will be susceptible to ultrasonic or
other high-frequency vibration.
6. Quality check under actual loading
To assure reliability, check the sensor
under actual loading conditions. Avoid
any situation that may adversely affect its
7. Other handling precautions
1) That using the wrong pressure range or
mounting method may result in accidents.
2) The only direct pressure medium you
can use is dry air. The use of other media,
in particular, corrosive gases (organic
solvent based gases, sulfurous acid
based gases, and hydrogen sulfide based
gases, etc.) and media that contains
moisture or foreign substances will cause
malfunction and damage. Please do not
use them.
3) The pressure sensor chip is positioned
inside the pressure inlet. Never poke
wires or other foreign matter through the
pressure inlet since they may damage the
chip or block the inlet. Avoid use when the
atmospheric pressure inlet is blocked.
4) Use an operating pressure which is
within the rated pressure range. Using a
pressure beyond this range may cause
5) Since static charge can damage the
pressure sensor chip, bear in mind the
following handling precautions.
• When storing the pressure sensor chips,
use a conductive material to short the
pins or wrap the entire chip in aluminum
foil. Plastic containers should not be used
to store or transport the chips since they
readily become charged.
• When using the pressure sensor chips,
all the charged articles on the bench
surface and the work personnel should be
grounded so that any ambient static will
be safely discharged.
6) Based on the pressure involved, give
due consideration to the securing of the
pressure sensor DIP type and to the
securing and selection of the inlet tube.
