Piezo Memory

Piezo, refers to the “piezoresistive” effect of the silicon sensor. A piezoresistive semi-conductor will see a change in resistivity due to a change in mechanical stress. Hence, a change in pressure or temperature results in a change in resistance. Some people call these tools "sapphire" or "strain” gauges. In every case, the same piezoresistive silicon sensor is used.

Piezo is less expensive - Less than half the price of a quartz pressure gauge.

Piezo is small – Which means it responds quickly to changes in pressure and temperature. This makes piezo gauges suitable for gradients.

Piezo is fast – We have piezo circuits which can sample up to 32,000 times per second. Perforating events can be captured with this high data acquisition rate.
