Precautions for Correct Use


(1) Only air can be used as pressure media on the product directly. It is prohibited to use pressure media including corrosive gases (e.g.
organic solvents gases, sulfur dioxide and hydrogen sulfide gases), fluid and any other foreign materials.
(2) The products are not water proof. The product shall be kept dry in use excluding the sensor port.
(3) The product shall not be used under dew-condensing conditions. Frozen fluid on sensor chips may cause fluctuation of sensor output
and other troubles.
(4) The product shall be used within rated pressure. Usage at pressure out of the range may cause breakage.
(5) The product may be damaged by static electricity. Charged materials (e.g. a workbench and a floor) and workers should provide
measures against static electricity, including ground connection.
(6) The product shall not be dropped and handled roughly.
(7) The product shall not be used under dusty or damp condition.
(8) Do not wash the print circuit board after the pressure sensor is mounted using solvent. It may cause a mal-function.
(9) Please connect the sensor terminals according to the connection diagram.
(10) The product shall not be used under high-frequency vibration including ultrasonic wave.
(11) This product uses the elastic adhesive for bonding the lid, so do not add excessive stress to the lid.
(12) If soldering is not fit, then this product may catch fire or get hot.
(13) There is a possibility that the peripheral circuit board or some electronic part generates heat while driving this product. Please handle
with care.
(14) Do not tear down this product.
(15) Please do not use the sensor after following case;
- excessive shock added to the terminal of the sensor
- the sensor lid decapped
- the sensor dropped
(16) If you use other conditions described in this document, please check yourself in advance.

●Environmental conditions for transport and storage

(1) The product shall not be kept with corrosive gases (e.g. organic solvents gases, sulfur dioxide and hydrogen sulfide gases).
(2) The products are not water proof. The product shall be kept dry during storage.
(3) The outer box strength may be degraded depending on the storage conditions. Please use the product in order.
(4) For this product, please keep away from direct sunlight or ultraviolet rays.
(5) The product shall be kept in appropriate conditions of temperature and humidity.
(6) The product shall not be kept under dusty or damp condition.
