PNI Sensor’s Geomagnetic Sensors eliminate any “blur” in your magnetic field measurements

  Based on PNI’s proprietary magneto-inductive technology, our

sensors deliver high-performance resolution and repeatability with over

10 times better resolution and over 20 times lower noise than the

leading Hall Effect sensor, enabling accurate calculation of heading and

orientation. They provide high gain, high sampling rates, and no

hysteresis. PNI’s magnetometers also do not require temperature

calibration or current set-and-reset pulses before each measurement.

Why Geomagnetic Sensors

  Geomagnetic sensors are used to measure the Earth’s magnetic field to

provide absolute reference and heading. But a large challenge is the

changing magnetic fields that temporarily distort the heading

information, such as metal parts in furniture, a passing car, or nearby

cell phones and computers. Compensating for these and other transient

magnetic anomalies requires the geomagnetic sensor to be able to

precisely distinguish between sensor noise (“blur”) and real changes in

magnetic field. PNI’s geomagnetic sensors lead the field in their

ability to reduce blur to establish the true magnetic field,

outperforming other magnetic sensors by orders of magnitude.

  Additionally, PNI’s Geomagnetic Sensors are simple to design in, and

the peak current requirement is dramatically less than Hall Effect

sensors. It isn’t surprising this patented technology has been proven

across a wide spectrum of applications, including motion tracking,

compassing, game control, TV and set-top box controllers, and magnetic

field measurement.

 

PNI传感器的地磁传感器可消除磁场测量中的任何“模糊”现象

  基于PNI专有的磁感应技术，我们的传感器具有高性能分辨率和可重复性，分辨率比的霍尔效应传感器高10倍以上，噪音低20倍，可以计算航向和方向。它们提供高增益，高采样率和无滞后现象。在每次测量之前，PNI的磁力计也不需要温度校准或电流设置和复位脉冲。

为何选择地磁传感器

  地磁传感器用于测量地球的磁场，以提供参考和航向。但是，一个巨大的挑战是不断变化的磁场会暂时扭曲航向信息，例如家具中的金属部件，过往车辆或附近的手机和计算机。补偿这些和其他瞬态磁异常需要地磁传感器能够地区分传感器噪声（“模糊”）和磁场的实际变化。 PNI的地磁传感器在减少模糊以建立真实磁场方面于该领域，其性能优于其他磁传感器。

  此外，PNI的地磁传感器设计简单，峰值电流要求远低于霍尔效应传感器。毫不奇怪，这项技术已经在各种应用中得到证实，包括运动跟踪，罗盘，游戏控制，电视和机顶盒控制器以及磁场测量。
