TCM2™ ELECTRONIC COMPASS, MAGNETOMETER, AND TILT SENSOR MODULE PNI Corporation's magneto-inductive sensors are not Full 3-Axis Magnetometer and 2-Axis Tilt based on traditional fluxgate or magneto-resistive Sensor designs. Unlike traditional technologies, PNI's magneto- In addition to compass heading, the TCM2 also inductive sensor changes inductance due to variances in supplies highly accurate pitch, roll, magnetic field ambient magnetic field strengths. Thus, power data and temperature information, allowing the requirements are far below conventional magnetic TCM2 to replace several sensors within a system. sensors. This makes PNI's sensors the preferred choice in a wide variety of applications. Accurate in Any Environment Ferrous metals in host systems often magnetize over Electronic Gimbaling time, misdirecting magnetic compass readings. In Unlike mechanically gimbaled 2-axis fluxgates, the addition, some systems also generate soft iron TCM2 has no mechanical moving parts. The use of 3 distortions. Soft iron can either misdirect or magnify single-axis magnetometers and a 2-axis tilt sensor allows existing magnetic fields, making calibration the TCM2 to be gimbaled electronically. Electronic extremely difficult. The TCM2 uses advanced gimbaling is a solid-state solution to compass tilt electronics and correction algorithms to counter the compensation that eliminates all moving parts and effects of hard and soft iron, enabling it to maintain a mechanical impediments to performance. This advanced high degree of accuracy even in the most demanding electronic gimbaling allows for tilt ranges of up to ±50º environments. and provides superior performance over the entire tilt range in real world conditions. Designed to Work in the Real World The TCM2's advanced technology allows you to design your system to cope with the challenges of your application. Plus, the command set is designed with flexibility and adaptability in mind: many of the parameters are user-programmable.
