Uptime, servicebaarheid en veiligheid

De keuze van de juiste apparatuur is cruciaal voor een optimale processtroom. Verhoog de uptime en zorg tegelijkertijd voor maximale veiligheid. Een fout kan dramatische gevolgen hebben: ongeplande uitval van medewerkers, hoge kosten en aanklachten.

How do you know that your plant complies with explosion protection regulations?

A certain number of analyses must be carried out and the results properly documentedPlease refer to our website at www.mt.com/ind-hazrisk for addtional information on this subject.

To answer this and more questions regarding the applicable regulations in your country, the mechanisms of explosion protection, and the technologies available, we invite you to join our free online webinars.

The good old bomb box: a thing from the past
Once the Zone or Division has been defined, there are not many alternatives available regarding the appropriate technology to use. Historically, Ex flameproof die cast enclosures have been used to protect equipment in Div 1 or Zone 1/21 classified areas. Intrinsically safe equipment can often provide a more cost effective alternative to Ex enclosures. However, in the past, the range of intrinsically safe solutions has been limited.

For this reason for more advanced applications the preference was to enclose the required equipment in the so called ‘bomb box’. The ‘bomb box’ solution had the advantage that the same equipment can be used both outside and inside the zone. The significant disadvantage is  its serviceability. In case of any failure which requests the intervention of a specialist, the ‘bomb box’ can be opened only after the hazard has been temporarily removed (i.e., to shut down the process and to purge/vent the environment). The alternative would be to remove the whole system, and service it far away from the Zone. In this case, again the operations shut-down is required. A ‘bomb box’ proves to be very sub-optimal.

The other advantage of the ‘bomb box’ used to be the cost of installation. As the intrinsic safe systems used to be expensive and require complex wiring, the rather expensive ‘bomb box’ solution appeared competitive. However, intrinsic safety has become much more affordable and simple to install. Today, a modern intrinsically safe piece of equipment can provide the same functionality as equipment made for safe areas.

"Breakthrough Product of the Year 2010!"
‘Processing Magazine’ has voted the intrinsically safe weighing terminal IND560x as Breakthrough Product of the Year 2010. 

What makes the IND560x a breakthrough product?

The IND560x is a state-of-the-art product because it brings into the classified Zone1/21 or Div1 areas exactly the same functionality of the IND560 family of terminals. A particular highlight is the availability of solid state active/active I/O that allows for straightforward control of valves directly in the Zone 1/21 Div 1, without any additional PLC and complicated wiring.

The IND560x is your gateway to uncompromised weighing in classified areas!
