A measurement system may comprise a sensor wire, a sensor, and a transceiver unit. The sensor wire may comprise an insertable portion configured to be inserted in a blood vessel of a patient's body. The sensor is disposed within the insertable portion at a distal end of the sensor wire. The sensor is configured to measure or detect a non-physiological parameter when inserted inside the patient. The transceiver unit is adapted to generate a communication signal and to transfer information related to the non-physiological parameter to an external communication module using the communication signal. The communication signal includes sensor values related to the non-physiological parameter. The transceiver unit may comprise a housing adapted to be connected to a proximal end of the sensor wire and configured to remain external to the patient's body.
