Ex barrier and intrinsically safe pressure sensors ? an inseparable pair

Clapp Castillo — Thu, 02 Nov 2023 07:33:46 +0000

Within the European Community, intrinsically safe pressure sensors may only be used in hazardous areas if they are installed together with an Ex barrier. The combination of pressure sensor and Ex barrier must meet the ? pressure gauge หน้าปัด 4 นิ้ว ? relative to the 94/9/EC ATEX directive. Not absolutely all combinations of sensor and barrier from different manufacturers fulfil this condition.
On the one hand, it might be that the safety or Ex characteristic values do not match, however, the functional characteristics must also match the application. So, even though the safety-related data match, the couple of Ex barrier and pressure sensor may not match since, for instance, both components work ?passively?.
(Additional information on the subject ?active?/?passive? can be found in the blog article ?Electrical circuitry for pressure sensors: when is a sensor active, and when passive??)
Therefore, factors to consider that you only use barriers and sensors together whose safety-related data and function-related data match one another. We therefore directly recommend, inside our intrinsically safe pressure sensors? data sheets, a potentially compatible intrinsically safe Ex barrier.
If you have any further questions, our sales department will gladly will give you detailed application consultation.

Metso Outotec slurry pumps to treat tails at SevGOK iron ore project

Engineering Dobersek in Germany and Severniy Mining and Processing (SevGOK) in Ukraine have chosen Metso Outotec’s mill discharge pumps for Severniy’s greenfield course of waste thickening plant, the OEM says.
Metso Outotec’s pumps might be used to pump the iron ore concentrate plant’s waste sludge into the settling ponds from the thickeners. The 22 pumps to be delivered by Metso Outotec include 10 massive high-capacity MDM700 pumps. Together, the pumps are capable of dealing with a total quantity of 117,500 cu.m/h of waste sludge.
“SevGOK’s advanced is ร้านซ่อมเครื่องวัดความดัน of its type in Ukraine, and Engineering Dobersek in Germany has designed it,” Axel Stappen, Managing Director, Engineering Dobersek GmbH, says. “With this funding, SevGOK aims to lower environmental impacts and prices by decreasing power consumption and water usage. They selected Metso Outotec pumps due to their reliability and efficiency, and the good assist Metso Outotec has provided of their earlier initiatives.”

Michael Nienhaus, Head of Sales, Slurry Pumps, Germany, Metso Outotec, says: “We are delighted to have been chosen to provide our MD series pumps to SevGOK’s project. To give an thought of the dimensions of an MDM700 pump, it can weigh as much as 31 t and be 2.eight m in diameter, and have a formidable pumping volume of up to 9,650 cu.m/h. The MDM pumps operate in very demanding circumstances, and we’ve designed them to function reliably and to withstand exceptional put on.”

Metso Outotec mill discharge pumps have been designed for mill circuit purposes, such as SAG/ball mill discharge pumps and hydrocyclone feed. Special emphasis has been positioned on parts which have to face up to distinctive put on from coarse heavy solids and move turbulence, the corporate says.
