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.
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.

However, it is important to be aware of the effect. The sensitivity of the SITRANS AS 100 Sensor decreases with increasing temperatures at a rate of approximately 0.5% per degree Celsius.
Low alarm gives early indication of problems in the diverter gate or slide gate, or of blockage or mate- rial shortage in the hopper. 7ML19985DM02 SITRANS AS 100 – INSTRUCTION MANUAL Page 11...
