Jewell Instruments - Superior Solutions for Motion Sensors

When harnessing the accuracy of an electronic compass, a number of factors, including magnetic conditions, can greatly impact performance. Here are two examples of these conditions and how to fix them.
1. Static Permanent Magnetism
The source of a local permanent magnetic field can be a piece of hard iron (hence the common name), a constant DC current, or some other type of magnet.  This source of error can be significantly reduced by calibration. The curve in Figure 1 shows that...

Whether precision measurements need to be taken in extreme temperatures, areas with vibration, noise or even underwater, there is a sensor that is built for it. Many applications expose sensors to dust or moisture, but sealing is intended to protect...

Precision inertial sensors are so sensitive that even noise waves can be detected as vibration. For many applications, noise is inevitable, but noise interference in the sensor’s readings is unacceptable. Here is what causes this disruption and what...

Jewell Instruments will be an exhibitor at Innotrans 2018 at Messe Berlin in Berlin, Germany on September 18 – 21. Innotrans is held every other year and is the leading international trade fair for rail transportation technology. The Jewell sensors and...
