    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
