Seven tips and advice for signal conditioning devices in hazardous areas

Many areas in the process industry are classified as hazardous areas. Electrical equipment such as signal conditioning devices in these zones must be intrinsically safe (I.S.) - but there are more aspects to consider when selecting signal conditioning devices and solutions for these areas...

1. Consider multifunctional devices

Choosing?a?few?devices?to be used in a wide range of applications gives you more?flexibility and cost-efficiency.

?2. Look for ease of use

Select devices that are easy to use and service – it will save you time as well as training and maintenance costs.

3. Check approvals

Check that your devices have the approvals you need – approvals may vary according to where your installation is located.

Below are the approvals?we?offer on our intrinsically safe (I.S.) products.

4. Go for devices with low power consumption

Select?devices?with?low?power?consumption?– it is more?cost-efficient?and a?greener?choice.

?5. Consider?mounting?options

Devices that offer different?mounting?options give?you flexibility when installing and easy commissioning -?some examples are: standard DIN rail, power rail, or?a backplane solution.?

6. Seek?knowledgeable?advisors

When?in?doubt, or?maybe?just?wondering?if and?how?you?can?make?your?installations more?efficient, ask an I.S. specialist.

?7. For SIL applications, select a supplier that designs for safety?

Selecting a manufacturer and devices fully assessed?according to IEC 61508?gives you built-in safety and?makes it easy for you to comply with the IEC 61511 site standard.
