The new analyser of gas GIR5500 of Hitech instruments, the analyser PGA3510 of SupersSystems and the ovens of calibración portable Transcal of Pyrocontrole, stand out, between other solutions, in the stand of Entesis Technology in Expoquimia (Big enclosure Via of Fira of Barcelona, of the 14 to 18 November).

Analysers of biogás

Entesis Technology distributes the new analyser of biogás GIR5500 of Hitech instruments, that exposes in his stand of Expoquimia. The team, with certification ATEX for zone 2, offers continuous monitoring, a wireless option ATEX and a robust and resistant design that is easy to keep and apt for a wide rank of applications.

The series of analysers GIR5500 is ideal for applications of biogás. These gases are usually a mix of methane (CH₄) and carbon dioxide (CO₂) together with oxygen (Or₂) and sour sulfhídrico (H₂S) that have implications on the efficiency and security. They are available the versions of 2, 3 or 4 gases with different apt configurations for classified zone 2.

The methane and the carbon dioxide are both gases invernadero. The methane is an important gas for the engines of cogeneration. If it does not use like fuel, burns in the pilot flame to produce carbon dioxide that is less harmful. Hitech Uses sensors by infrared to measure the methane and the carbon dioxide. These sensors are especially designed to resist the frequently humid atmospheres and corrosivas of these applications.

The oxygen is an indicator of important process so much in the gas of dump as in the one of digester. In the gas of dump, a low reading can indicate the presence of a subterranean fire in the dump, whereas a high reading can indicate one on extraction of the dump. In the gas of digester, a high reading can indicate a decrease of the microbial activity been due to poisoning. For this application, Hitech uses a special electrochemical cell of long life designed to work in presence of acidic gases like the carbon dioxide.

The acid sulfhídrico is present in the gas of dump and in the one of the digester in different quantities according to the composition of the substrate. The acid sulfhídrico can be extremely corrosivo for the generators and the continuous measure can warn damages very costly. Hitech Has developed an only system that allows the continuous measure of H₂S. With a rank of 2.000 ppm of H₂S, can achieve a long life of the sensor.

Is important to condition the sample according to the different applications. Hitech Supplies of series internal filters, a bomb of aspiración internal and alarms of low discharge. It recommends besides a filter coalescente external and options of cooling to delete the water. The cupboard in if it includes heating to ensure that the steam of water do not condense inside the analyser. Hitech Can recommend the complete system if they facilitate all the characteristics of the flow of gas.

The design of the GIR5500 does it ideal for this type of applications: a robust and resistant cupboard and an interior with suitable internal filters. The instrument has a modular design that allows to follow working when a sensor requires maintenance. All the modules of sensors can be substituted in situ to reduce to the maximum the time of stop.

Precise measurements in atmospheres of thermal treatments

PGA3510.

Analyser PGA3510 of SuperSystems (3 gases by infrared+oxygen) allows the precise measurement of the carbon according to the composition of the gas, as well as the verification of the potential of carbon according to the CQI-9. It is a team of easy handle, that has of bomb of aspiración integrated. It works with battery and his calibración, in the same team, is simple. Besides, it has software to print tables.

Ovens of calibración portable

Entesis Also distributes the ovens of calibración portable Transcal of Pyrocontrole (Group Chauvin-Arnoux). The range Transcal provides precision, reliability and ease of use, with a rank of 50 to 1.100 °C. Nowadays it is indispensable to verify periodically the quality and the precision of the probes of temperature. This verification has to be able to realise/realize without affecting the production. Of here, the need of a light team, handy and portable that allow to realise/realize a calibración of quality in situ.

Treats of ovens with electrical and regulatory resistance PID incorporated that allows a calibración precise. They have an important depth (180 millimetres/millimeters) of penetration of the probe. A fan allows to diminish the time of cooling and realise/realize different calibraciones in a brief period of time. The handle facilitates the transport of these ovens. Optionally it can purchase a case of transport.

Regarding the method of calibración, the probes to calibrate enter in the lateral holes whereas the pattern enters in the central hole of diameter 10 millimetres/millimeters. The probes have to connect to an indicator and compare his values with the ones of the pattern. The different points of consign program directly in the regulator or road RS485 through the PC.
