Radio tower on the left is an antenna designed to transmit radio waves to a receiving antenna, like the one on the radio. However, as the drawing on the right shows, the same antenna that receives your favorite song can also inadvertently pick up noise from something like a welder, whose cables can act like a transmission antenna that’s broadcasting noise.

In this world three things are certain: death, taxes–and electrical noise, to paraphrase Benjamin Franklin. Electrical noise happens. Period. It can wreak havoc by injecting false signals onto encoder lines, or by overwhelming real signals entirely. It’s often intermittent, which can make diagnosing and fixing it a nightmare. But if you use a few simple techniques you can drastically reduce...   Read More »

Cable from the drawworks (located on or near the main platform) runs up to the crown block at the top of the derrick, then down to the traveling block. The top drive rotates the drill string; it is suspended from the traveling block, and is raised or lowered by the drawworks.

Where do encoders face their toughest operating conditions? One answer at the top of the list is in the petroleum industry, where encoders are used everywhere. In this post we’ll look at encoders in the oil industry, from beginning to end–the rough conditions encoders face on oil drilling rigs, how they keep oil flowing in transport pipelines, and the way they ensure accuracy at gasoline...   Read More »

E4T and S4T Miniature Encoders

Nuremberg, Germany — US Digital on Thursday announced that it is expanding its EC35 commutation encoder line with 3 new, higher resolutions, topping off at 60,000 CPR. The 3 new encoder configurations will make their official debut at SPS in Nuremberg, Germany. “Whether they are using commutation or not, the EC35 is a popular size and form-factor with a lot of our customers,” said Neal...   Read More »

If you need an encoder that can measure very small distances, which of the following is most important to you? High Accuracy? High Precision? High Resolution? All about the same? Here's a hint: in the everyday world, those terms might seem like they mean the same thing, but in the world of encoders, accuracy or precision won't help you solve this problem nearly as much as...   Read More »

Pipette and Pipettor

How do you attach an encoder to a liquid? Encoders usually attach to a part of the system that moves—and in a pump, the part that moves is a liquid! How do you attach an encoder to that? In actual practice, you don't. Every pump has a mechanism that moves a fluid. You attach the encoder to that mechanism. If a motor drives the mechanism, for example, you can mount the encoder to the motor...   Read More »
