The CEC Model 4-170 is a self-generating,piezoelectric accelerometer designed for medium temperature vibration measurement applications. This instrument provides a high sensitivity and stable output for continuous operation at temperatures as high as +500°F(+260°C). While the unit does not require power for operation, the accelerometer output must be operated into a charge converter that is designed
to accept a 100,000 ohm source resistance.
The 4-170 piezo ceramic sensing element is housed within a rugged case, where both the case and connector are made from Inconel 625.The mounting base incorporates a standard three-point mounting pattern on a 1.188”diameter B.C., common to many applications.The 4-170 series provides a balanced differential output that is isolated from the case ground.
