Environmental Compliance
Waste Electrical and Electronic Equipment (WEEE) Directive
GE Measurement & Control is an active participant in Europe’s Waste Electrical
and Electronic Equipment (WEEE) take-back initiative, directive
2002/96/EC.
The equipment that you bought has required the extraction and use of natural
resources for its production. It may contain hazardous substances that could impact
health and the environment.
In order to avoid the dissemination of those substances in our environment and to
diminish the pressure on the natural resources, we encourage you to use the
appropriate take-back systems. Those systems will reuse or recycle most of the
materials of your end life equipment in a sound way.
The crossed-out wheeled bin symbol invites you to use those systems.
If you need more information on the collection, reuse and recycling systems, please
contact your local or regional waste administration.

about this initiative.

Chapter 1. Features and Capabilities
1.1 Introduction
The Moisture Target Series 6 (MTS6) is a microprocessor-based,
single-channel hygrometer that measures moisture content in gases. It is
intended for Original Equipment Manufacturer (
suitable for a wide range of process conditions that require real-time
moisture measurement.
The MTS6 accepts any calibration range provided with GE probes (see
Chapter 5, Specifications for more information). It comes equipped with
two standard alarm relays, one fault alarm relay, and a single analog output.
It also has onboard data logging capability using an micro SD card.
1.2 Electronics Unit
The MTS6 displays measurement data on a liquid crystal display (LCD). You
can program your unit and enter probe information using the keys on the
front panel (see Figure 1). The MTS6 accepts line voltages of a universal
power supply from 100 to 240 VAC, or 24 VDC, depending on what is
ordered.
OEM) applications, and is

Chapter 1. Features and Capabilities
1.3 Probes
The moisture probe is the part of the system that comes in direct contact
with the process. The MTS6 uses any GE M Series (see Figure 2) or a
VeriDri probe (see Figure 3) to measure dew point temperature in °C or °F.
The sensor assembly is secured to the probe mount and is protected with a
sintered stainless steel shield (see Figure 2).
Note: Other types of shields are available upon request.

2.2 Selecting the Recorder Output
Note: By default, the recorder is set to the current output.
Note: The customer will provide their own cable for connecting the
recorder. Acceptable cables range from 16 to 26AWG.
The MTS6 has one isolated analog recorder output. The recorder output
provides either a current or voltage signal, which is set by switch S1 on the
main PC board.
Complete these steps to check or reset switch
WARNING! Never connect line voltage or any other power input to
S1 (see Figure 8 on page 7).

2.3 Mounting the Electronics Unit
The MTS6 unit can be installed in a panel up to 0.25 in. (6 mm) thick. See
Appendix A, Outline and Installation Drawings, for the required panel
cutout dimensions.
IMPORTANT: For NEMA 4 and IP66 installation, the MTS6 must be mounted
in a rigid, flat panel using the panel gasket and both mounting
brackets provided.
2.3.1Basic Mounting
To mount the MTS6 in a panel with a basic 94 mm (3.69”) x 46 mm (1.81”)
opening, refer to the following figures and complete the following steps:
1.Remove the side panel mount label prior to installation.

2.3.2Adapter Plate Mounting
Some customers may need to retrofit an MTS6 into a cut-out sized for GE’s
previous OEM panel-mount hygrometers: MTS5, MTS4 or PanaDry
models. The previous generations were of a larger size requiring a 5.40”
(137.2 mm) W x 2.65” (67.3 mm) H cut-out. The MTS6 is smaller, requiring
a 3.69” (94 mm) W x 1.81” (46 mm) H cut-out. For those customers who
need to retrofit the larger panel cut-out sizes, GE offers an optional adapter
plate. See Appendix A, Outline and Installation Drawings, for the required
panel cutout.
1.Fit the larger gasket around the adapter plate (see Figure 16).

2.4 Mounting the Sample System (cont.)
The sample system is normally fastened to a flat metal plate that has four
mounting holes. Upon request, GE can also provide the sample system in an
enclosure.
Complete the following steps to mount the sample system:
1.Fasten the sample system plate or enclosure to a vertical wall or panel
with a bolt in each of the four corners.
2.Connect the sample system inlet to the process and the outlet to the
return, using appropriate stainless steel fittings and tubing.
CAUTION! Do not start the process flow through the system
until the probe has been properly installed (see the
following section).
2.5 Installing the Probe
GE probes are usually installed in a sample system to protect the probe from
any damaging elements in the process. The probe is mounted in a
cylindrical container called the
your sample system.
sample cell, which is included as part of
Standard M2 probes and VeriDri probes are mounted into the sample system
or process line with 3/4-16 straight threads that are sealed with an o-ring.
Other fittings are available for special applications.
CAUTION! If the probe is to be mounted directly in the
process line, without a sample system, consult GE for proper
installation instructions and precautions.
Refer to Figure 24 on page 18, and complete these steps to install the probe
into the sample cell:
1.Insert the probe into the sample cell and thread the probe into the
sample cell fitting. Make sure you do not to cross the threads.
2.Tighten the probe securely.

3.Identify the sample cell inlet port as the connection that is perpendicular
to the installed probe.
CAUTION! For maximum protection of the aluminum oxide
sensor, the probe shield should always be left in place.
