4) Malfunction may occur near electric noises from static electricity, lightning, broadcast or amateur radio stations
and mobile phones.
5) Avoid use in a place where these products come in contact with water as the sensor does not have a splash-
proof construction.
6) Avoid use in an environment where these products cause dew condensation. When water attached to the sensor
chip freezes, the sensor output may be fluctuated or damaged.
7) Due to the structure of the pressure sensor chip, the output varies under light. Do not expose the sensor chip to
light when applying a voltage by using a transparent tube.
8) Do not apply high-frequency oscillation, such as ultrasonic waves, to the product.
■ Quality check under actual use conditions
These specifications are for individual components. Before use, carefully check the performance and quality under
actual use conditions to enhance stability.
■ Other precautions
1) The wrong mounting method and the pressure range may invite the risk of accidents.
2) Only applicable pressure medium is dry air. Avoid use in the corrosive gas (organic solvent, sulfurous acid
and hydrogen sulfide gases) or other mediums containing moisture or foreign substances. Such mediums may
damage or break the product.
3) The pressure sensor chip is located inside the pressure introduction port. Do not insert foreign substances,
such as wires, into the port as those substances may damage the chip and close the port. Do not block the
atmosphere introduction port.
4) Use electric power within the rated power range. Use beyond the range may damage the product.
5) Follow below instructions as static electricity may damage the product:
(1) For Storage, short the circuit between terminals by using conductive substances or wrap the whole chip
with aluminum foil. For storage and transportation, avoid plastic containers which are easily electrified.
(2) Before use, connect electrified materials on desk and operators to the ground in order to safely discharge
static electricity.
6) Carefully select and fix tubes, introduction pipes and products based on the working voltage. Please contact us for
any inquires.
7) After mounding the pressure sensor, prevent the potting agent from entering the pressure and the atmosphere
introduction ports when coating the circuit board. Use the elastic resin as the heated resin may expand, contract and
apply pressure to the sensor. After coating, carefully check if the sensor can be used.
Design and specifications are each subject to change without notice. Ask factory for the current technical specifications before purchase and/or use.
Should a safety concern arise regarding this product, please be sure to contact us immediately.
