Industrial Accelerometers

These piezoelectric vibration sensors have been designed for application under rough environmental conditions. They are dust and water protected. Their mounting base is insulated to avoid ground loops which may cause errors, particularly, close to big machinery. The cable has to be ordered separately according to the requirements of length and quality (e.g. high temperature, oil resistant, flexible metal tubing).
KSI84 series acceleration and velocity transmitters are compatible with 4-20 mA current loop equipment.
Useful technical information about piezoelectric accelerometers can be found on our Theory pages.
