1443 Series Accelerometers Specifications
1443-ACC-GP-T32-SC Accelerometer
General-purpose industrial accelerometers are recommended for permanent installation onto machinery or route-based
vibration data collection in predictive maintenance and condition-monitoring applications. Sensors with the shield wire
that is grounded to the case are non-standard. See Shield Wire Isolation Sensor and Cable Selection on page 8 ordering.
