Ultrasonic Thru-Beam Sensors: Cutting through the Haze

Posted by Patricia Stafford on Thu, Oct 30, 2014

What are ultrasonic thru-beam sensors?

Ultrasonic thru-beam sensors always come in pairs consisting of a dedicated emitter and a dedicated receiver. The evaluation and switching output electronics are located in the receiver. Using Teach-in or a potentiometer, you can adjust the receiver sensitivity for different distances between the emitter and receiver, or for different object sizes.

3 Myths About Industrial Sensors

Posted by Amanda Blakeman on Wed, Oct 15, 2014

Everyone has their own idea of what an industrial sensor is and what it does.  But you might be surprised at how many of these ideas are inaccurate.  Here are several misconceptions about industrial sensors:

Rotary Encoders are Everywhere!

Posted by Nick Ferguson on Wed, Oct 01, 2014

Have you ever entered an elevator and realized that the elevator cart was not level with the floor? Have you ever seen a conveyor system at the airport? What about measuring revolutions per minute or the actual CNC or robot position? What do all of these have in common? Rotary encoders!

Ask an Expert Industrial Sensors - Episode 5

Posted by John Appleson on Thu, Sep 18, 2014

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 is the slope of the output characteristic, and what is the linearity error value for inductive analog sensor NBB5-18GM60-I3?

2. Are inductive analog sensors, such as the NBB5-18GM60-I3, capable of detecting aluminum at a reduced distance, and do you have a correction factor for this?  

3. Photoelectric sensor MD17/73 has a plastic retaining nut to secure it on a mounting bracket. Is it possible to order just the retaining nuts? Due to location, they get damaged or lost and we don't want to replace the entire switch.

4. Photoelectric sensor - I'm trying to sense clear fluid being shot out of a small 0.11 in. diameter hypodermic needle. What sensor, if any can detect fluid flow start and stop? The water stream is only approximately 0.09 in. in wide.

5. Thru-beam photoelectric sensor - I need to detect wire strands as they pass a sensor. The strands are less than 1 mm diameter, moving up to 5 in./s (~0.13 m/s). Is a thru-beam  photoelectric sensor the best option? Which model would be best for my application?

Inclination Sensors Explained: My Slant on Things

Posted by Patricia Stafford on Thu, Sep 11, 2014

What is an inclination sensor?

Inclination sensors provide a simple way to measure and monitor the angles of stationary and moving objects. They are also called tilt sensors or inclinometers.

Different types of inclination sensors include “fixed range” and “programmable range.” An example of a fixed range sensor with fixed end points is one that has a range between ± 15°. Fixed range sensors are also known as fixed-point sensors. Programmable sensors may have an adjustable range of up to 360°. With a programmable sensor, you can adjust the range between different points by setting the endpoints for the output range. You can use 4 mA ... 20 mA for a 360° angle, a 180° angle, or some other finite angle of your choosing.

Inclination sensors can be single axis or dual axis. A single-axis sensor measures in only one axis, while a dual-axis sensor can measure in two axes of orientation.

Thinking Outside the Box with Intrinsic Safety

Posted by Robert Schosker on Thu, Sep 04, 2014

Have you or are you still thinking about taking that leap of faith to intrinsic safety? With current and voltage limited to levels below that which can cause an ignition, a 50% safety factor even under fault conditions, and the ability to wire in accordance with general purpose wiring methods, there shouldn’t be another thought. But wait. What about my field device?

In the article 'Choosing Your Intrinsic Safety Device',  by Aaron Hand, Executive Editor, Automation World, find out what you need to know about the other half of the intrinsic safety equation.

If, after reading this article, intrinsic safety sounds like something you would be interested in learning more about, we're here to help. What questions do you have?
