2. Installation
2.1 Introduction
Purpose:
Installation of SDM unit, SDM adapters and cables.
The SDM is a 24 VDC powered standalone sensor with 4-20 mA output and HART protocol
Installation should be performed by skilled installation technicians (mechanical and electrical).
The SDM, which is installed in a specially prepared spool section, wafer section or is used in conjunction
with a pipe adapter (weldolet) has a ceramic sensor face which should be in contact with a representative
portion of the slurry to be measured.
IMPORTANT:
The surface of the ceramic front face must be aligned with the inside pipe diameter. Otherwise the SDM
will fail to measure correctly.
Installation:
In chapter 2.1 and 2.2 there are common instructions for mounting the SDM adapter in a process
line. This chapter is valid for all sensor adapter types.
In chapter 2.3 to chapter 2.5 the different SDM adapters mounting instructions are described. In
“Provided by Rhosonics” a description of the different types of SDM adapters.
In chapter 2.6 the SDM mounting instructions are described.
