1. PRODUCT DESCRIPTION

The DM-TX6-X is designed to monitor explosions hazard induced by the presence of

flammable gases or vapours (hydrogen, hydrocarbons, alcohol, etc…).

The DM-TT6-K is designed to monitor the gas concentration in %vol. induced by the presence

of some special gases or vapours (hydrogen, helium, carbon dioxide, etc…).

The detector can be connected directly to a large range of traditional controllers or

Programmable Logic Controllers (PLC).

The DM-TX6-X and the DM-TT6-K may be fully configured using the portable communication

terminal (TLU600) in ATEX areas, providing flexibility to the user.

These detectors can be configured also using the Hart portable terminal TLH700 (in option).

The MultiXplo and MultiTox are also available for use in an addressable network system with

distributed intelligence, SYNTEL. For more information, please refer to the Syntel module

interface operating manual.

1.1. Application Fields

The DM-TX6-X and the DM-TT6-K are suitable for indoor and outdoor uses and offer a fast

response time. Typical applications include:

•Storage and use of combustible/flammable gases and

vapours(DM-TX6-X),

•Monitoring of processes with flammable products

•Hydrogen detection in inert atmosphere and in high

concentration (DM-TT6-K),

•Chemical and petrochemical plants

•Pharmaceutical industry

•LNG/LPG

•Oil and gas facilities

1.2. DM-TX6-X

The detectors are calibrated on 100% LEL (Lower Explosive Limit) of a particular gas or

vapour.

The DM-TX6-X is a MultiXplo detector based on a transducer with thermo-catalytic oxidation,

which requires oxygen to function properly.

In the event of a long period without oxygen, the measurement will no longer be

representative of the concentration of gases or vapours.

The characteristics of the device can also be altered by the presence of certain catalyst

poisons such as silicone fumes, vapours of organometallic compounds and, to some extent

by halogenated compounds.

MultiXplo / MultiTox Page 8 / 60 NOSP15759-Rev 10

1.3. DM-TT6-K

The DM-TT6-K is a MultiTox detector, based on catharometric transducer. Its measurement

range is usually expressed in terms of %vol. relative to a particular gas (for example 5 %vol.

H2, 5 %vol. He...).

The DM-TT6-K measurement principle is based on the heat exchange between a heated

filament and a "cold" separation. The effectiveness of the exchange between those two

elements depends, in particular, of the thermal conductivity value of the mixture which

separate them.

This measurement principle is very stable, and able to operate with high gas concentrations.

In this configuration, the presence of oxygen is not essential, and catalytic poisoning is not an

issue.

1.4. Technical specifications

Each detector is constructed as follows:

•A wall-mounted support secured by two screws, allows assembly of a cable gland

(M20) (optional) and up to three plugs.

•An explosion-proof housing (epoxy coated aluminium or 316 SS) containing:

•A set of tropicalized electronic cards

•An infrared communication head, located on the detector’s housing. It

allows communication with the remote control (TLU600).

•A colour coded cartridge. Yellow for Combustible Gas Detector with thermo-catalytic

cells (DM-TX6-X) and brown for catharometers (DM-TT6-K). The cartridge is located

in the lower part of the detector, and it is connected to the detector body by an open

ring leaving the label visible.

1.5. Detection Cartridge

Detection Cartridges are explosion proof designed.

They are common to all Oldham Simtronics MultiXplo and MultiTox-K products in order to

reduce the number of spare parts.

•DM-RX6-X and DM-RT6-K: Network versions for Syntel loop,

•DM-TX6-X and DM-TT6-K: « Telecapteur » versions,

For combustible gas detector’s cartridges, if the difference between the storage temperature

and the operating temperature does not exceed 20°C, the nominal characteristics are

obtained after a few minutes. Otherwise, wait for the balancing thermal unit, about half an

hour.

Catharometer cartridges (cartridges K) need to be in thermal balance with their environment

to provide nominal performance. Thus, when the cartridges have been unpowered more than

half-an-hour, a warm-up time is required when power is restored. The duration of warm-up

is usually range from ½ hour to 4 hours, depending on the temperature difference between

the cartridge and the ambient temperature.

The cartridge temperature information is available on the TLU.

The cartridge must not be unplugged when the detector is powered.

1.6. Communication interfaces

1.6.1. Wireless Configuration Tool

Information and status of the detector are available via the wireless configuration tool

TLU600.

Configuration and tests are performed using this wireless configuration tool (IrDA protocol).

This tool is common for all Oldham Simtronics MultiFlame, MultiXplo

and MultiTox products.

The TLU600 provides access to devices, which would otherwise

require major logistic operations for maintenance or for

configuration (calibration …).

For more details, please refer to the wireless configuration tool

operating manual.
