Sensing device

A sensing device comprising:

• a sensor retainer comprising:
• a first coil;
• a first sensor;
• and
• a first light communication tube;
• a sensor cartridge detachably coupled to the sensor retainer and comprising:
• a second coil;
• a second sensor;
• and
• a second light communication tube;
• and
• at least one controller electrically coupled to the sensor retainer and communicatively coupled to the sensor cartridge, wherein the at least one controller is configured to:
• measure a current flowing through the first coil based at least on transmitted pulse of a predefined frequency;
• determine if the measured current is above a predefined threshold value;
• if the measured current is above the predefined threshold value, apply a constant frequency of power to the sensor cartridge via the first coil and the second coil;
• and
• perform a wireless communication between the at least one controller and the sensor cartridge via the first sensor and the second sensor using the first light communication tube and the second light communication tube.
