Introduction
While the SITRANS LU10 is typically used to monitor material level in open or closed 
vessels, any process which requires a distance measurement (within the system range) 
is a candidate for SITRANS LU10 application. 
Refer to 
Technical Reference
 Application Examples for detailed descriptions of a small 
sample of process measurement requirements to which the SITRANS LU10 may be 
applied. 
Throughout this manual (unless stated otherwise) references to material level also apply 
to any material or object surface to be monitored by the SITRANS LU10. 
Important SITRANS LU10 Features 
Fixed Features
Enclosure 
Chemical resistant, light weight, dust tight, liquid tight, easy to work with. 
LCD 
Large digits for Reading and programming value displays. 
Graphic Symbols for continuous indication of operating conditions. 
Programmer
20 tactile feedback keys or Dolphin (SITRANS LU10/RS-232C interface) 
each with magnetic mounting and infrared interface (ordered separately). 
Scanning
Substantially reduces equipment costs for additional vessels (present or 
future).

Communications ready when equipped with an appropriate Siemens Mill-
tronics SmartLinx module. 
Speed
Fast 16/32 bit microprocessor at 16.7 MHz clock speed. 
1 vessel (point) per second scanning speed capability. 
Reliability
Surface Mount Technology (SMT) also provides for full features in a com-
pact design. Sonic Intelligence® ensures all measurements are accurate 
and reliable. Immune to power interruptions, all programming is stored 
indefinitely. Dynamic operating data is retained for one hour and updated 
immediately on power resumption.
