Continuous measurements on industrial machines or the materials that these machines are making, moving, or processing can be categorized into two main types of sensors: position measurement sensors, and distance measurement sensors. It’s a somewhat subtle distinction, but one that … Continue reading
The standard for hydraulic fluid in the industry is mineral oil, which is a dielectric medium that does not conduct electricity. Yet environmental concerns have led to the search for alternatives that are less harmful in case of leaks and … Continue reading
Hydraulic actuators can be used to open and close a valve’s position. In automation architectures, a linear position sensor is used within the hydraulic actuator to provide continuous position feedback. The linear position sensor is installed into the back end … Continue reading
In linear motion applications, it is often desirable to eliminate the need to make a homing run to re-acquire the reference position for an incremental linear encoder. The homing routine may need to be eliminated to save processing time, or … Continue reading
The classic linear position feedback solution for hydraulic cylinders is the rod-style magnetostrictive sensor installed from the back end of the cylinder. The cylinder rod is gun-drilled to accept the length of the sensor probe, and a target magnet is … Continue reading
Linear encoders – absolute or incremental? Incremental encoders are simple, inexpensive, and easy to implement, but they require that the machine be homed or moved to a reference position. Absolute encoders don’t require homing, but they’re usually more expensive, and … Continue reading
In a previous blog post, we looked at the basic operating principle of magnetostriction and how it is applied in a linear position transducer. In this post we’re going to take a more in-depth look at this popular sensing technique … Continue reading
Transporting hot materials (ex. steel slabs) from one location to another via a walking-beam is common place in steel manufacturing. In the past, rotary encoders have typically been used to provide the precise feedback of rotary movement for these types … Continue reading
