Application
Attention
1) Do not use the sensor in water, rain, or outdoors.
2) To maintain operational reliability and service life, use the sensor only within the specificed temperature range.
3) The sensor has a water resistant structure, however, attaching a cover to prevent direct contact with water will help
improve reliability and prolong product life.
4) Avoid using the sensor where there are chemical vapors, especially strong alkails or acids (nitric acid, chromic acid,
or hot concentrated sulfuric acid).
