Heading Sensors - 3-Axis Compass Module - Legacy TCMs

 

Unmatched performance even in the most demanding conditions - ideal for:
ROVs, targetting, GPS navigation, drilling, robotics, vehicle sensing and tracking + more


The Legacy TCM5

PNI will continue to build and support these TCM products, but for new designs, the High Performance Digital Compass is recommended. The legacy TCMs include the TCM2.5, TCM2.6, TCM3 and TCM5.

The TCM family of sensor modules combines PNI's patented magneto-inductive sensors with a 3-axis MEMS accelerometer in a single temperature and noice-stabilised design that's inherently free of offset drift. Using PNI's proprietary hard and soft-iron correction algorithms, PNI TCMs calibrate out most magnetic anomalies for repeatable, high-resolution measurement across a broad range of navigation and tracking applications.

Even in the most demanding conditions and environments, PNI TCMs deliver unmatched performance, making them ideal for applications such as high performance ROV navigation, targeting systems, GPS system navigation, vehicle sensing and tracking, drilling and downhole applications, robotics and more.

2-axis measurement High Resolution / Accuracy
3-axis measurement Low power
3D Orientation Module
Hard iron correction Integrated Processor
Soft Iron Correction    

 

Our legacy TCMs include the following models and configurations:

TCM2.5 and TCM2.6: Cost-effective, reliable compass heading with PNI ASCII Interface.

TCM3: Extended tilt range and 0.5° accuracy with PNI Binary Interface.

TCM5: 360° tilt-range and 0.3° accuracy with PNI Binary Interface.

1 Using standard (full range) calibration method
2 The maximum sample rate is dependent on the strength of the magnetic field and typically will be from 25Hz to 32Hz
3 Operation at slower sample rates will reduce power consumption
