Application

The non-heated or electrically heated M&C
dilution unit DIL-1 /H is used in analysis
technique to dilute the sample gas or com­ponents in the sample for example in case of
toxic gases, moisture measurement or emis­sion measurement.

The M&C dilution unit is based on the func­tional dilution technique which is proved
since years in the M&C gas sample probe
SP2000-H/DIL.

Description

The M&C dilution units DIL-... are mounted on
a plate for wall mounting. The version DIL-1 is
not heated and works at ambient tempera­ture. The version DIL-1/H is electrically heated
up to 180 °C . It is additionally equipped
with a lagged cover (version for 320 °C on
request).

A capillary thermostat controlls the tem­perature, adjustable from 0-180 °C.
A high temperature limiter and a low tem­perature alarm is included.

The connection of the heated lines is
made without cold bridges in the heated
part. Before the dilution gas enters the
dilution unit, it is heated up to operat­ing temperature via a gas pre-heater. In
order to protect the dilution part against
contaminations, internal protective fil­ters are installed for the sample gas and
the dilution gas stream. Calibration gas can be
feeded via the integrated connection.

A precision pressure controller with pressure
gauge is used for adjustment of the necessary
admission pressure of the dilution gas. Via a
vacuum pressure gauge, the function of the
dilution injector is controlled.

Both, pressure controller and pressure gauges
have to be ordered separately. Two versions
are available: Set -A (-A1) is mounted directly
on the mounting plate and control panel type

-S (-S1) is suitable for external 19» rack mount­ing. A shut off valve and a flowmeter for
adjustment of the calibration gas are included
in the version -S (-S1).

The dilution unit can realize dilution ratios
of 10:1 to 500:1. In case of high dilution
ratios, a respective small quantity of gas
is sampled from the process. Optionally
a bypass injector -B (Option I) is available
integrated right in front of the dilution unit
in order to shorten the response time in case
of operation with atmospheric pressure or
low pressure. In case of option I, an additional
pressure controller is included in both mount­ing versions.

The construction of the dilution unit guaran­tees easy maintenance and operation inde­pendent from process temperatures.
