NOTE:
1. DESIGN RESTRICTION/PRECAUTIONS
■
This sensor is designed for use in air environment. Do not use it in liquid.
■
In the case where secondary accidents due to operation failure or malfunctions can be anticipated,
add a fail safe function to the design.
■
In the case where this sensor is to be hold in housing, use soft buffer between sensor and housing.
The front part of this sensor must be free to vibrate. If this part is hold, its characteristics will vary.

2. USAGE RESTRICTION/PRECAUTIONS:
■
To prevent sensor malfunctions, operational failure or any deterioration of its characteristics, do not
use this sensor in the following, or similar conditions.
a) In strong shock or vibration.
b) In high temperature and humidity for a long time.
c) In corrosive gases or sea breeze.
d) In an atmosphere of organic solvents.
e) In dirty and dusty environments that may contaminate the sensor front.
f) Over specified allowable input voltage(Vp-p)
■
Do not solder adding stress on outer lead, also do not apply stress like spin or pressure just after
soldering.
In case you form the leads, support the root firmly.
3. WARRANTY:
■ Period
Warranty period is one year after delivery.
■
Scope
Defective sensors attributable to manufacturer’ responsibility shall be replaced for free during the
warranty period.
However, following cases are out of the scope.
a) Unsuitable handling or misuse by user.
b) Modification or repair by user.
c) Any other cases not due to manufacturer’responsibility such as natural calamity, accident .etc.
This scope covers only replacement.
Any loss derived from failure or malfunction of the sensor, or cost on replacing is excluded from this
warranty scope.
