  • Page 11: Mounting

    Notes: • To ensure the most ideal location, test the SITRANS AS 100 by clamping the Sensor to the application, and running a trial period to determine the system's performance. The acoustic emission level can be monitored by a voltmeter across the analog output.
  • Page 12: Temperature Considerations

    If welding, weld must be a continuous bead. Tacking does not provide sufficient acoustical coupling. • Do not arc weld on equipent connected to a SITRANS AS 100. Remove the SITRANS AS 100 or disconnect electrically to avoid current flowing through the sensor.
