Acetylene

A colorless ﬂammable gas, lighter than air. Mixtures with air are explosive. It results from

the interaction of calcium carbide with water. In industrial production, acetylene is mainly

manufactured by the pyrolysis of light hydrocarbons.

Acetylene is widely used for welding and cutting of metals. The usage of acetylene as a

feedstock in the chemical industry declines due to cost and environmental considerations.

Synonyms/Trade Names: Ethine, Ethyne.

Odor

Odorless or with a faint ethereal smell if pure. The

commercial-grade may have a garlic-like smell due to

impurities.

Hazards

Highly ﬂammable.

Gas/air mixtures are explosive. Forms explosive

acetylide compounds with copper, mercury, silver &

brasses (containing more than 66% copper).

Asphyxiant. Non-toxic, but, when generated from calcium

carbide, it can contain toxic impurities such as traces of

phosphine and arsine.

Butane

A colorless ﬂammable gas that is heavier than air. The term “butane” is used for any of two

structural isomers (n-butane or iso-butane, with unbranched and branched-chain

respectively) or for their mixture. Occurs in light petroleum fractions.

Butane is used mainly as a fuel and as a feedstock in organic synthesis. It is applied also

as a propellant in aerosol sprays and may be used as an ozone-friendly refrigerant.

Mixtures of butane with propane and other hydrocarbons are referred to as LPG (liqueﬁed

petroleum gas).

abused directly from a highly pressurized container, and

can result in death from asphyxiation and ventricular

Product description

E2630 series gas detectors are compact and easy-to-use instruments. The devices utilize

novel fully calibrated and temperature compensated gas sensors with excellent

repeatability, stability and long lifetime.

Two relays RE1 and RE2 with switching contacts can be used to control alarm sirens,

ventilation fans, shut-off valves or other actuators. The devices are equipped with a visual

and acoustic alarm. The version of your detector is marked on the package.

Safety requirements

Misuse will impair the protection of the product. Always adhere to the safety provisions

applicable in the country of use.

Do not perform any maintenance operation with the power on. Do not let water or foreign

objects inside the device.

Removal of the PCB from the enclosure voids the warranty. Do not touch the electronic

components directly, as they are sensitive to static electricity.

Connection diagrams can be found in the connections section. The device might not

perform correctly or be damaged if the wrong power supply is connected.

External circuits connected to the equipment should have suﬃcient insulation rating

according to the environmental conditions and equipment power.

A disconnecting device that is marked as such and easily accessible should be included in

the installation of this product.

Operating conditions

The device should be used both in a non-hazardous indoor area and in a basic

electromagnetic environment, where the latter is deﬁned in EN 61326-1. Avoid strong

mechanical shock and vibrations. Avoid corrosive atmosphere and areas highly

contaminated with dust, oil mist, etc. Keep the instrument away from direct sunlight. A

sudden temperature or humidity change might affect the sensitivity of the sensor.

When stored without powering in normal air for a long period, or in an environment

contaminated with organic vapors or volatile oils, the sensor may show a reversible drift in

resistance according to the environment.

Installation guidelines

E2630-LEL Rev 23.03.2021

There are no precise rules or standards to follow when installing gas detectors. The

following points must be taken into account:

●Application (air quality control or leakage detection.)

●Properties of the space under investigation (room geometry, direction, and

velocity of airﬂows, etc.)

●For gases lighter than air install the sensor higher than the potential

leakage/generation source or near the ceiling. Combustible gases lighter than air

are hydrogen, methane and acetylene. Propane and butane are heavier than air

and tend to sink. It is recommended to place the sensor lower than potential

leakage or generation source.

●The device should be accessible for maintenance and repair.

The aforementioned conditions above will affect the coverage area of the device. however,

the coverage area for a detector is usually between 2.5 to 5 meters radius.

For early leakage detection install the sensor as close as possible to the potential leakage

sources (ﬂanges, valves, pressure reducers, pumps, etc.), taking into consideration other

points listed above.

For general area monitoring without deﬁnite leakage sources, the detector should be

distributed evenly in the room.

Do not locate the detector close to ventilation openings and strong air currents. Avoid the

areas without air circulation (corners, niches) as well.

For personal safety control, the detectors are installed in the breathing zone (at the height

of the head of people or animals). The recommended sensor position is vertical, pointing

downwards.
