Sensing system and a process for detecting one or more physical parameters of an undercarriage and/or a vehicle, and undercarriage and vehicle provided with said sensing system

A sensing system for detecting physical parameters of a part to be monitored, wherein the sensing system comprises a sensor assembly including:

• a fixing element including a fixing pin configured for being fixed to the part to be monitored;
• a sensing circuit configured for detecting one or more physical parameters of the part to be monitored;
• a fixing interface configured for being fixed to the fixing element;
• a protecting housing configured for being fixed to the fixing interface and containing at least part of the sensing circuit so as to protect it from the environment outside of the protecting housing and/or from one or more of the following agents or influence factors:
• mechanical stresses, chemical substances, dirt, liquids, dust, atmospheric agents, heat, cold, thermal shocks.
