Abstract
A rugged sensor and method for manufacturing such, for use in hostile environments, the sensor exhibiting high mechanical strength to protect the sensor from physical damage. The sensor system also including a modular component that may variously be connected to the sensor to extension thereof, the modular component also exhibiting high mechanical strength to protect electrical conductors located therein.
Claims22
A sensor comprising:
- a first component formed from a first component material;
- a first conductor formed from a first conductor material, said first conductor electrically connected to said first component;
