Mounting - Solids Applications - Siemens st-h Operation Manual

Mounting
• Do not mount the transducer directly to metal. Use a plastic type coupling and nipple for
isolation (customer supplied).
• Mount the transducer so that it is above the maximum material level by at least the
blanking value. Refer to the associated controller manual.
• For liquid applications, the transducer must be mounted so that the axis of transmission is
perpendicular to the liquid surface. For tanks with a parabolic top, an Easy Aimer may be
used to mount the transducer face perpendicular to the liquid surface.
• For solids applications, use a Siemens Milltronics Easy Aimer to aim the transducer.
• Where the transducer is mounted to a standpipe, the inner standpipe surface and end
must be smooth and free of burrs, ridges, and seams.
• Consider the optional temperature sensor when mounting the transducer.
• Do not overtighten mounting. Hand tightening of the mounting hardware is sufficient.
Mounting – Solids Applications
Non-Corrosive Applications
In solids applications, mount the transducer so that it is aimed toward the low level draw point. Use
the optional Siemens Milltronics Easy Aimer to facilitate this mounting.
