Introduction

Small Size and High Temperature Quartz Accelerometer

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.

Features

1. Excellent start repeatability

2. Good environmental performance

3. Analog output

4. Adjustable output range

5. Small dimensions
