A sensor is an important component in measuring and controlling system. Several sensors use the high technology to fabricate such as a vibration sensor. Consequently, its make a vibration sensor have a high price and rarely in the market. Therefore, many researchers develop it to get a sensor with good a characteristic and low price. In order to get a good characteristic of vibration sensor, we required the low frequency vibration generator as sensor calibrator. This paper presents the design of a low frequency vibration generator instrument as a seismic sensor calibrator using an optocoupler counter sensor. The vibration generators consist of a mechanical and an electronic system with separate in two different boxes. A direct measurement was conducted to measure the sensor output and the time to count the frequency. The accuracy and precision were determinate based on the indirect measurement (statistical and graphical analysis). Testing result of the instrument shows that the sensor accuracy is about 94.2% with average of correctness 0.955. Accuracy average of vibration generator is 0.98 and the precision is about 0.976.
