Ask an Expert Industrial Sensors - Episode 9

Posted by John Appleson on Wed, May 13, 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. Is extended addressing necessary when creating two separate ASI interface circuits on one AS-Interface gateway?
  2. What do the wire colors mean, and what is their function, on the ML8 series photoelectric sensor?
  3. How do you troubleshoot the beam width and sensing range of a UB4000-30GM series ultrasonic sensor?
  4. What kind of sensor is best to measure the density and color differentiation of a marking within a medium?

Laser Sensors that Measure the Distance!

Posted by Amanda Blakeman on Thu, May 07, 2015

You read that right.  Now with Pulse Ranging Technology (PRT), laser sensors can determine the distance to an object by emitting short, high-energy light pulses over a given distance.

Using AS-Interface to Monitor Valve Position

Posted by David Fink on Thu, Apr 30, 2015

An automated valve assembly typically consists of a rotary travel process valve, a pneumatic actuator, a solenoid valve and in some cases, a bracket to mount the valve to the actuator.  The operation of the valve assembly is accomplished by energizing and de-energizing the solenoid. But how can the operator in the control room tell if the valve is open or closed?

Remote Monitoring via KVM Extenders

Posted by Lou Szabo on Thu, Apr 23, 2015

KVM Extender Selection Criteria

Industrial keyboards, video monitors, and/or mice are usually located within 6 feet or 2 meters of the source PC or thin client. However, there are times when you need to mount an industrial display farther away from the source signal—sometimes in a different building or type of location, such as outdoors, on the process floor, and/or in a hazardous location.

Ask an Expert Industrial Sensors - Episode 8

Posted by John Appleson on Wed, Apr 15, 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. Magnetic sensor MB60-12GM50-E2: What is the performance of this sensor like if the sensing surface is less than 10 mm away from the sensor?

2. How does the magnetic field sensor 41FY1 work? Is it a two-part magnetic sensor?

3. What is the required target size for the inductive sensor NJ5-18GM-N-5M? Will a 1/8 in. wide keyway that is .03 in. deep on a 4 in. diameter shaft work?

4. I'm trying to connect an NBB5-12GM50-E0-V1 inductive sensor to a PLC, but I am unable to make the two work together correctly!

5. Do you have cable connectors? What about for specialty cable types?

Remote I/O—Getting on Board the Bus to Better Communication

Posted by Patricia Stafford on Wed, Apr 08, 2015

What is remote I/O?

Remote I/O refers to a remote input/output system that transfers data from analog to digital form so that field devices can communicate with a network.

Types of remote I/O include LB and FB. Both LB and FB perform the same function. The difference between them is the type of hazardous environment and methods of protection each one is rated for. LB remote I/O is rated for mounting in Zone 2 and 22, Div. 2 with intrinsic safety protection methods Ex ia, Ex ib, and Ex ic. FB remote I/O is rated for mounting in Zone 1 and 21 with intrinsic safety protection methods Ex ia and Ex ib.

Industry 4.0 Comes to Hannover Fair 2015

Posted by Patricia Stafford on Wed, Apr 01, 2015

The Internet of Things is an up-and-coming technology which is set to transform the way we live. Simply put, it allows machines to communicate directly with each other over the Internet. This connection between machines will lead to greater convenience and efficiency based on a more rapid exchange of information. Everyday examples might include a car telling a garage door when to open or close, a stove turning itself on to boil a pot of tea that will be ready for you when you come home from work, a timer setting thermostats, and your refrigerator letting you know when you’re running low on groceries.

AS-Interface Safety Monitor Setup Options to Combat Nuisance Shutdowns

Posted by Tim Cicerchi on Wed, Mar 25, 2015

Safety at Work has been a part of AS-Interface for over 10 years now.  It is a very reliable means of networking industrial safety products.  Very demanding applications need extra configuration in the software to prevent nuisance shutdowns.  These shutdowns can be caused by high vibration on the machine opening up mechanical contacts or high noise sources disrupting network communications.  Here are some software settings to reduce or eliminate these nuisance shutdowns.

Fieldbus Physical Layer Diagnostics Saves the Day!

Posted by Andreas Hennecke on Tue, Mar 17, 2015

...and, the goose!

As I was reading John Rezabek's recent article "Can Improved Physical Layer Diagnostics Save Christmas Dinner?", a few thoughts came to mind.

John pointed out that keeping the installation — junction boxes, instrument housings — sealed from moisture ingress is one of the big challenges for both fieldbus and 4 mA … 20 mA installations.

Industrial Displays for Division 2 Hazardous Areas

Posted by Lou Szabo on Thu, Mar 12, 2015

Customers often want to know what exactly is a Class I, Div. 2 industrial display. Or, what choices there are for HMI visualization and machine control in a Division 2 area, and if a purge system is required. The answers depend on what is connected to the display, and the type of HMI software. This information helps you decide whether to look at an industrial monitor, a panel PC, or a networked monitor via thin client or KVM back to a host in a control room.
