Solenoid Inlet

Introduction

Thermo Fisher Scientific
The solenoid inlet is a sample gas selector that can be used in place
of the RMS valve assembly on applications with a limited number of
sample inlets.
There are several bulk gas handling components and connections
inside the instrument enclosure, and therefore this inlet cannot be
used with hazardous area systems.
The stream selector assembly is available in two sample line
configurations with either a 6-port manifold or fast response single
stream inlet. Each version comes with 6 calibration gas ports as
standard, though additional calibration ports can be added, in banks
of 5, as an optional extra. The inlet uses the same micro capillary
assembly and transfer line technology as fitted to other inlet systems.
Gas flow (sample and calibration) is monitored with a differential
pressure flow sensor, similar to the RMS.
Safety
Warning! The following must be considered in addition to all
safety notes elsewhere in this manual covering the system as a
whole.
Depending on the nature of the gases in use (sample and calibration
gases), precautions may need to be taken to avoid inhalation of,
contact with, or ignition of these gases. In general, these precautions
are as follows.
Always use the correct tubing size for the fittings supplied

and the correct nut / ferrule assembly.
Do not exceed the pressure and flow specifications detailed

below.
Leak check all external pipe work and recheck periodically.

Leak check inlet system periodically, as defined in this

manual.
Before opening up any gas handling part of the system, it

may be necessary to purge the system with a suitable inert or
non-hazardous gas. Gas lines and the exhaust line should be
isolated. Consideration should be given to the possibility and
implications of failure of the isolation mechanism used.
Warning! It is the responsibility of the instrument user to assess the
potential hazards involved in working on any gas handling parts of
the system.
