🤔 Do you have any concerns? We'll answer them!

• Concern: The sensor is flexible, but can I bend it without restrictions? -> Answer: The sensor is flexible, but to maintain integrity, it is recommended not to bend the active area more than 90°.
• Concern: How accurate are the pressure measurements? -> Answer: These thin-film sensors are ideal for qualitative analysis of trends and relative pressure magnitude, not for absolutely precise measurements.
• Concern: What happens if the maximum pressure range is exceeded? -> Answer: Exceeding the range will not damage the sensor. Once the pressure returns to the normal range, the sensor will continue to function without problems.
• Concern: Is the sensor water resistant? -> Answer: The sensor material is not intended for direct contact with liquids and additional protection is required for waterproofing.

❓ Frequently Asked Questions (FAQ)

Can a thin-film pressure sensor measure absolutely accurately?

These sensors are primarily intended for qualitative analysis of pressure change trends or for determining the relative magnitude of the tested pressure, not for absolutely precise measurements.

Is it possible to bend and fold the sensor?

Although the sensor is flexible, bending the pressure-sensitive active area may damage the wires. We recommend not bending the sensor more than 90°.

Is the sensor resistant to high temperatures?

The sensor is designed to operate in a temperature range of -20°C to +65°C, ensuring reliability in many common applications.

How do flexible sensors respond to pressure?

Flexible pressure sensors are resistive: the greater the force exerted on the sensor, the lower its electrical resistance.

Is the sensor waterproof?

The material of the flexible pressure sensor is not intended for direct contact with liquids and additional protection or a housing is required for waterproofing.

What surface does the sensor work best on?

Flat and smooth surfaces are optimal. Moist air or dirt particles can cause false sensor triggering.

Was the sensor damaged when the range was exceeded?

Exceeding the recommended range will not damage the sensor. Once the pressure returns to the normal range, the sensor will continue to function normally.
