Precautions for Correct Use

Handling the Sensor

(1) Only air can be used as pressure media on the products 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. Please keep dry in use.
(3) Don't use the products under dew-condensing conditions. Frozen fluid on sensor chips may also cause fluctuation of sensor output and any other troubles.
(4) Don't put foreign materials (e.g. a wire and a pin) into a connecting tube. It may cause breakage of pressure sensor chips or fluctuation of sensor output caused by clogging the tube.
(5) Use the products within rated pressure. Usage at pressure out of the range may cause breakage.
(6) Don't use under high-frequency vibration including ultrasonic wave.
(7) The products may be broken by static electricity. Charged materials (e.g. a workbench and a floor) and workers must provide measures against static electricity, including ground connection.
(8) Overpowering terminals may deform them and detract their solder abilities. Don't drop and handle the products roughly.
(9) Don't use the products under humid or dusty condition.
(10) Terminals connection of pressure sensors must be handled as directed by a connection diagram.

Environmental Condition for Transportation and Storage

(1) It is prohibited to keep the products with corrosive gases (e.g. organic solvents gases, sulfur dioxide and hydrogen sulfide gases).
(2) The products are not water proof. Please keep dry during storage.
(3) An anti-static treatment has been applied to the sleeves. Please note the following points.
1. Getting wet may remove an anti-static treatment and eliminate its effect.
2. The sleeve may feel sticky under hot and humid condition due to the nature of the anti-static treatment.
3. Anti-static has aging degradation. It is prohibited to keep the sleeves for more than six months. The sleeves are also non-reusable.
(4) Keep in an appropriate temperature and humidity condition specified as
Temperature : 5 to 30°C , Humidity : 40 to 60%.
(5) As the lead is plated with silver, there is a possibility of being tarnished depending on storage condition.
Not guarantee the tarnishing after shipping. Be careful the method of storage.
(6) Don't keep the products under humid or dusty condition.

Mounting Method

• Use lands on the printed-circuit boards to which the sensor can be securely fixed.
• Fix pin No.2 on the printed-circuit boards, not fixed causes fluctuation of sensor output signals.

Soldering Method

• Due to its small size, the thermal capacity of the pressure sensor is low. Therefore, take steps to minimize the effects of external heat.
• Dip soldering bath: Max. 260°C, within 10 sec.
• Soldering iron: Max. 260°C, within 10 sec.
• Do not heat the case of sensor package, heat only terminal.
• Use a non-corrosive resin type of flux. Since the pressure sensor chip is exposed to the atmosphere, do not allow flux to enter inside.

Cleaning

• Since the pressure sensor chip is exposed to atmosphere, do not allow cleaning fluid to enter inside.
• Avoid ultrasonic cleaning since this may cause breaks or disconnections in the wiring.
• Do not wash the print circuit board after the pressure sensor is mounted using detergent containing silicone. Otherwise, the detergent may remain on the surface of the pressure sensor.

Coating

• Do not coat the pressure sensor when it is mounted to the print circuit board.
