◆Class II non-linearity repeatability: 40-50μg/g2

  • Introduction

ER-QA-03F is a small size accelerometer which is mainly used for oil well logging. The output current is linear with the force. The operator can select a reasonable sampling resistor according to the calculation to achieve the highest precision output. The product can also be used for static testing and dynamic testing, which is a standard vibration sensor.
