Introduction

Dilution probes are used wherever dilution of the sample gas is necessary for the measurement of one
or several sample gas components. Examples are the measurement of toxic gas components, mois-
ture measurements or adjustment of the sample gas concentration to the analyser measuring range.
The M&C gas sample probe type SP190-H/DIL-EX2 T* is based on the SP180-H-EX2 T* probe, and is
used for continuous gas sampling and dilution.
M&C gas sample probes provide direct insitu ultra-fine filtration during continuous gas sampling for
analytic measurements. In this way, part of the necessary maintenance work for a system is
concentrated on a single point. This filter technology has the major advantage that dust mixtures
consisting of ultra-fine and coarse dusts can be optimally retained with the least possible maintenance
work.
Optimal adaptation of the sample probe to processing conditions and to measurement work is a
necessary condition for a measurement system to work smoothly. Basically, the gas sample should be
kept to a necessary minimum. This is made possible thanks to optimised downstream gas processing
using M&C components. Only in this way it is possible to reduce maintenance to a minimum while
ensuring maximum availability.
The SP190-H/DIL-EX2 T* is certified for appropriate use in the specified Ex zones.
Only operate the gas sample probe according the specifications stated in this
instruction manual and in the extended manufacturer documents.
The type SP190-H/DIL-EX2 T* is not designed to separate the gas explosion zone
without appropriate precautions by the operator.
The gas sample probe is classified for three different temperature classes:
Version
SP190-H/DIL-EX2 T2
SP190-H/DIL-EX2 T3
SP190-H/DIL-EX2 T4

A one alarm contact (low temperature alarm) is available to monitor the
temperature of the gas sample probe:
