Ask an Expert Industrial Sensors: Episode 15

Posted by John Appleson on Thu, Jan 28, 2016

This episode of Ask an Expert for industrial sensors examines and provides answers to interesting sensing questions we've received from customers just like you. We explore and answer these questions:

1. What does the LED message 'bad' mean on my WCS-IP 111 interface module?
2. Does the 973EX4WI-A10T inductive sensor require an intrinsic safety barrier or circuit?
3. How can you test the SJ10-N inductive slot sensor?
4. The RC10-14-NO inductive ring sensor is used in a rivet gun, but can give a false count at times. How to correct this?

AS-Interface Safety Networks and Safelink

Posted by Tim Cicerchi on Tue, Dec 29, 2015

Have you ever used a safety network and ran out of room?   There are only a certain number of allowed addresses on each safety network, and once you reach this number you have to start a new safety network.  When it comes to AS-Interface, Safety at Work, the limit is 31 safety devices per network and 62 safety devices per gateway/safety monitor.  This may seem like a lot, but the addresses go quickly.

Intrinsic Safety: Isolated Barriers Bring out the Best in Protection

Posted by Patricia Stafford on Tue, Dec 22, 2015

What is intrinsic safety?

The best form of protection is prevention. So when it comes to electricity, low voltage and current flow is the way to go.

Keeping people and equipment safe is a top priority for anyone who works with electrical equipment in a hazardous area. Intrinsic safety is key. An intrinsically safe system is one in which the current and voltage are kept so low that there is not enough energy to produce arcs, sparks, flames, or explosions.

Ask an Expert Industrial Sensors: Episode 14

Posted by John Appleson on Thu, Dec 17, 2015

This episode of Ask an Expert for industrial sensors examines and provides answers to interesting sensing questions we've received from customers just like you. We explore and answer these questions:

1. Inductive ring sensor RJ21-E2 - is there a reduction factor for aluminum targets, or is it for ferrous targets only?
2. Is there a minimum mounting distance between WCS positioning system read heads?
3. Do you have a photoelectric sensor that can be installed outdoors in temperatures down to -40 °C?
4. Is there a proximity sensor that will detect steel, but not aluminum?
