Question

If a negative pressure is applied to a positive pressure sensor, may the sensor fail to operate properly?

Answer

If an absolute value of pressure is above a withstanding pressure,the sensor may be damaged.

For example, when using the Digital Pressure Sensor "E8F2-A01C" a withstanding pressure is 400kPa. This means that as long as a pressure in a range from -400 to 400kPa is applied within 30 seconds, the sensor is not damaged
