Cautions and warnings

The pressure sensors should be stored in their original packaging. They should not be placed in

harmful environments such as corrosive gases nor exposed to heat or direct sunlight, which may

cause deformations. Similar effects may result from extreme storage temperatures and climatic

conditions.

Avoid storing the pressure sensors in an environment where condensation may form or in a location

exposed to corrosive gases, which will adversely affect their performance.

The thermal capacity of the pressure sensor is normally low, so steps should be taken to minimize the

effects of external heat. High temperatures may lead to damage or changes in characteristics.

A non-corrosive type of flux resin should normally be used and complete removal of the flux is

recommended.

Avoid rapid cooling due to dipping in solvent. Note that the output signal may change if pressure is

applied to the terminals during soldering.

Media compatibility with the pressure sensors must be ensured to prevent their failure (see page 2).

The use of other media can cause damage and malfunction.

Never use them in atmospheres containing explosive liquids or gases.

Ensure pressure equalization to the environment, if relative pressure sensors are used.

Avoid operating the pressure sensors in an environment where condensation may form or in a

location exposed to corrosive gases. These environments adversely affect their performance.

If the operating pressure is not within the rated pressure range, it may change the output

characteristics.

Be sure that the applicable pressure does not exceed the overpressure, it may damage the pressure

sensor.

Do not exceed the maximum rated supply voltage, it may damage the pressure sensor.

Do not exceed the rated storage temperature range, it may damage the pressure sensor.

Temperature variations in both the ambient conditions and the media (liquid or gas) can affect the

accuracy of the output signal from the pressure sensors. Be sure to check the operating temperature

range and thermal error specification of the pressure sensors to determine their suitability for the

application.

Connections must be wired in accordance with the terminal assignment specified in this publication.

Care should be taken as reversed pin connections can damage the pressure sensors or degrade their

performance.

Contact between the pressure sensor terminals and metals or other materials may cause errors in the

output characteristics.
