TABLE 1

NOTES

1.This sensor is designed for use in air. Do not use this sensor in fluid.

2.In case where this sensor is to be hold in housing, use soft buffer between sensor and housing. The front

part of this sensor vibrates in large.

If this part is hold, its characteristics will vary. The top must be free to vibrate.

3. 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.
