Applications for use in hazardous areas are also being considered.

This is a must in explosive environments.” he continues.

The device must not be used in environments at risk from explosions.

Components are certified according to the requirements in potentially explosive atmospheres.

Do not use the unit in environments where there is a risk of explosion.

They are suitable for use in an environment in which there is a risk of explosion and permit transmission of measured values over a large distance.

In an environment which is liable to explosions, forked light barriers can be used as optical sensors.

The EE300Ex is dedicated for highly accurate humidity and temperature measurement in potentially explosive environment.

Self priming, self venting, low pulsation, low noise level, suitable for use in explosive environments

A version for use in explosive environments and other special technical solutions is possible.

At this stage it has only adopted legislation aiming at alignment in the fields of legal metrology (non-automatic weighting equipment) and pre-packaging and equipment used in potentially explosive atmospheres (ATEX).

Furthermore, machinery designed and constructed for use in a potentially explosive atmosphere must be marked accordingly.

BACKGROUND OF THE INVENTION The present invention relates to a new and improved construction of a gas sensing unit for use in environments containing explosive gases, which is operatively connected with a central station to thereby form a gas sensing signaling system.

With the addition of an environment posing an explosive danger (for example the individual current circuits in an underground coal mine) it is however very desirable to keep the necessary electrical power as small as possible for safety.

Such ionization fire alarm can be particularly advantageously employed when there are to be expected electrical disturbances in the lines or when working in an explosion-endangered environment or atmosphere.

An electronic control system is associated with problems or is inadmissible for certain fields of application, for example in a potentially explosive environment.

Such applications are particularly advantageous in explosive environments or in areas with strong electrical or magnetic fields.

The object of the invention is to propose a fully hydraulic control system for a double piston pump of the type specified at the beginning, which control system can also be used in a potentially explosive environment.

The safety standards for operating such voltage transfer devices in environments that are subject to explosion hazards require more expensive and complicated designs of these voltage transfer devices.

This makes the apparatus particularly suitable for use in explosion-endangered environments and at difficultly accessible measurement locations, e.g. on chimneys.

As a result of the structural separation between optical and mechanical elements on the one hand and electronic components on the other, the method or apparatus according to the invention can also be used in explosion-endangered or damaging environments and in particular on difficultly accessible locations, because only the sensor arrangement exclusively having optomechanical elements has to be installed at the measurement location.

Machinery must comply, as far as the risk from explosion due to its use in a potentially explosive atmosphere is concerned, with the provisions of the specific directives in force.

The measuring device of this invention is extremely robust inasmuch as it lacks mechanically movable parts and is suitable for application under rough operational conditions, also in environments with explosion hazards.

The supplier of safety technology assures thereby the further application of the sensor cable for process control and monitoring in particular in hazardous areas like the chemical industry.

Approved for Hazardous Areas 1, 2, 21 and 22, it provides safety during maintenance work, rescue and security work in potentially explosive atmospheres caused by flammable gases, mist, vapors or dusts.

For evacuating explosive gases or for processes that take place in explosive environments we have developed OktaLine ATEX, which is based on the proven concept of the convection cooled roots pumps.

The Makita SK102 is designed for use in areas perma- nently habitable by humans, do not use the product in explosion hazardous areas or in aggressive envi- ronments.

In order to identify additives filled into big bags, also in explosive atmospheres unequivocally, a chemical company counts on an ATEX certified UHF solution.
