Abstract:
1. An industrial process transmitter comprising: a housing comprising: a sensor for measuring an industrial process parameter selected from the group consisting of pressure, temperature, level and flow of an industrial process fluid and generating a sensor signal that is a function of the measured process parameter; transmitter electronics positioned within the internal storage space of the housing to connect to the internal power connector, and connected to the sensor for conditioning the sensor signal and producing a transmitter output representative of the measured process parameter, the transmitter electronics being capable of communicating with an external control loop; a manually driven power generator positioned within the internal storage space of the housing to connect to the internal power connector for supplying power to the sensor and the transmitter electronics through the internal power connector; a supercapacitor positioned within the internal storage space and connected to the transmitter electronics to store power generated by the manually driven power generator; and a casing for housing the manually driven power generator, the casing configured for storage in the internal storage space of the industrial process transmitter such that the manually driven power generator connects to the internal power connector.
