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
