1. Introduction

The GTR 210 is a universal gas transmitter for the detection of combustible gases, toxic gases or

oxygen. The gas transmitter can be equipped with six different types of sensing elements. It converts the

measured gas concentration to a physical concentration value. The transmitter shows the concentration

on an integrated display and transfers it via the current port to an evaluation unit.

Three versions of the transmitter are available:

1. GTR 210 Standard:

The GTR 210 Standard is the basic model of the GTR 210 family. It provides as User interface

a LCD graphic display, a touchpad with six keys and one current output.

2. GTR 210 EX:

This is the flame-proofed version of the GTR 210 Standard. It can be installed in hazardous

areas (class II zone 1). Therefore several types of approval has been awarded. As the basic

model the GTR 210 EX provides a current output signal.

3. GTR 210 Comfort:

This version is a standalone device. It can be operated without an evaluation unit. It is

supplied directly with 230V AC 50Hz / (optional 115V AC 60Hz). Additionally to the current

output, three alarm relays and one fault relay are supported.

All three versions can be built with the following alternatives:

• IP 54: for an ambient temperature of -25°C...+55°C

• IP 66: for an ambient temperature of -25°C...+60°C

The version as well as the alternative can be identified precisely via the type plate.

The electronics of the gas transmitters will also work for temperatures down to approx. -40°C, but at

temperatures lower than -25°C the display may loose it´s readability.

2. Conformity

The gas transmitter GTR 210 incorporates a universal gas measuring head which is manufactured both

as standard and in an explosion-protected version.

The safe measuring function for inflammable gases and the software were tested by

Dekra-Exam-GmbH. The GTR 210 conforms to Safety Integrity Level 1 (SIL1).

The GTR210, GTR210-Comfort and GTR210-Ex conforms to the following standards.

• DIN-EN 60079-29-1: 2008 Explosive atmospheres - Part 29-1:

Gas detectors - Performance requirements of

detectors for flammable gases

• DIN-EN50271: 2011 Electrical apparatus for the detection and

measurement of combustible gases, toxic gases or

oxygen - Requirements and tests for apparatus

using software and/or digital technologies

• DIN-EN50270: 2007 Electromagnetic compatibility - Electrical apparatus

for the detection and measurement of combustible

gases, toxic gases or oxygen

The explosion-protected version has been checked by KEMA Quality B.V. and corresponds to the

protection type

Ex II 2 G Ex d e ia mb IIC T4 Gb

The EX GTR 210 conforms to the following standards:

• DIN-EN 60079-00: 2010 Explosive atmospheres - Part 0:

atmospheres

• DIN-EN 60079-01: 2008 Explosive atmospheres - Part 1:

2.1. MED option

Gas transmitters with the MED option are made from seawater-resistant materials.

In the MED option, the gas transmitter GTR210 fulfils the requirements of the marine equipment

directive 2014/93/EU.

Its conformity has been demonstrated in an EC type examination by the body for ship safety (transport

employer's liability insurance association). With the MED option, the transmitter also conforms to the

following standards:

• IEC 60092-504: 2001 Electrical installations in ships - special

+ corrigendum 2011 features - control and

instrumentation

• IEC 60533: 1999 Electrical and electronic installations in

ships - electromagnetic compatibility

It thus fulfils the requirements of Item 3.54 of Annex A1 of the marine equipment directive.

The maritime field of application of the transmitter covers the detection of flammable and toxic gases

both below and above deck.

The use of the transmitter on the bridge or for measuring oxygen is not permitted.

3. Method of Operation

The gas transmitter consists of a two-part housing.

The lower part is used for the wall fixing and for connecting the control cable.

The measurement cell and the electronics of the gas transmitter are integrated into upper part of casing.

A capacitive keyboard and a graphics display are located behind a window incorporated in the upper

part.

For the detection of various gases, chemical measurement cells, sensors according to the process of

catalytic combustion, thermal conductivity, semi-conductors, infrared sensors and photo-ionization

detectors, are used.

The sensor signal is processed by the gas transmitter and converted into a physical display format. The

measured gas concentration is indicated at the same time on the display and transmitted to the

evaluation electronics unit outside of the explosion-hazard area via a 4-20 mA interface. This unit

processes the measured value, displays it as concentration and carries out possible control and warning

functions.

In the Comfort version of the GTR 210, alarm and fault relays are additionally installed on the lower

housing. Thus the Comfort version can be used as a real "standalone" gas measuring device, without

additional central unit.

4. Installation & Operational Startup

4.1 Installation

The gas transmitter GTR 210 is designed for stationary gas monitoring. The installation should be

implemented at a location which is clean, sheltered from the weather and as vibration-free as possible.

The installation must be such that the sensor is accessible for maintenance work.

Before the installation and operational startup of the gas transmitter, a check should be made to ensure

that the type of sensor is suitable for use in the on-going environment.

In case of detection of inflammable gases and oxygen, the current version of EN60079-29-2 "Explosive

atmospheres - Part 29-2: Gas detectors - Selection, installation, use and maintenance of detectors for

flammable gases and oxygen" must be observed.

Shielded cable must be used for the signal line.

3 conductors are required for the standard and Ex-protection implementation.

The shield of the measurement signal line has to be connected unilaterally on the ground potential in the

alarm evaluation unit. It is not allowed to connect the shield with the gas transmitter. Moreover it should

be paid attention that the shield of the measurement signal line is put down possibly only for a short time

on the gas transmitter site. This is to prevent the transfer of EMC dysfunctions to the transmitter.

The required cross-section of the conductors depends on the length of cable used. The voltage drop on

the supply line must be such that the supply voltage does not fall below 18 V at the gas transmitter. The

following table lists common cross-sections and their maximum cable lengths. Both supply and return

lines are considered in the lengths of the cables.

Example Cross-section Maximum length

0.25 mm2280 m

J-Y(ST)Y 2x2x0.6 0.28 mm2320 m

J-Y(ST)Y 2x2x0.8 0.5 mm2570 m

0.75 mm2850 m

1.0 mm21100 m

1.5 mm21700 m

The system must be voltage-free before and during operational commissioning work.

Please note that the housing must be connected to the equipotential bonding.
