42 mems gauge pressure sensor 2smpp precautions precautions for correct use handling ? only air can b e used as pressure media on the products directly. it is prohi b ited to use pressure media including corrosive gases (e.g. organic solvents gases, sulfur dioxide and hydrogen sulfide gases), fluid and any other foreign materials. ? the products are not water proof. please keep dry in use. ? don't use the products under de w-condensing conditions. frozen fluid on sensor chips may also c ause fluctuation of sensor output and other trou b les. ? don't put foreign materials (e.g. a wire or pin) into connecting tu b e. it may cause b reakage of pressure sensor chips or fluctuation of sensor output caused b y clogging the tu b e. ? use the products within rated pr essure. usage at pressure out of the range may cause b reakage. ? don't use under high-frequency vi b ration including ultrasonic wave. ? the products may b e b roken b y static electricity. charged materials (e.g. a work b ench and a floor) and workers must provide measures against static electricity, including ground connection. ? overpowering terminals may deform them and detract their solder- a b ility. don't drop or handl e the products roughly. ? don't use the products under humid or dusty condition. ? terminals connection of pressure sensors must b e handled as directed b y a connection diagram. environmental conditions for transport and storage ? it is prohi b ited to keep the products with corrosive gases (e.g. organic solvents gases, sulfur dioxide and hydrogen sulfide gases). ? the products are not water proof. please keep dry during storage. ? an anti-static treatment has b een applied to the sleeves. please note the following points. 1. getting wet may remove an anti-static treatment and elimi- nate its effect. 2. the sleeves 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 prohi b ited to keep the sleeves for more than six months. the sleeves are also non- reusa b le. ? don't keep the products under humid or dusty condition. mounting ? use lands on the printed-circuit b oards to which the sensor can b e securely fixed. ? fix pin n o.2 on the printed-circuit b oards, not fixed causes fluctua- tion of sensor output signals. soldering ? 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 b ath: 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 b reaks or discon- nections in the wiring. coating ? do not coat the pressure sensor when it is mounted to the print cir- cuit b oard. ? do not wash the print circuit b oard after the pressure sensor is mounted using detergent containing silicone. otherwise, the deter- gent may remain on the surface of the pressure sensor. definitions 1. offset voltage is defined as the ouput voltage at 0 kpa rated pressure 2. positive span voltage is defined as the alge b raic difference b etween the output voltage at 50 kpa rated pressure and and the output voltage at 0 kpa rated pressure.
