DEVICE FOR SUBMERSIBLE TELEMETRY Russian patent published in 2017 - IPC G01D3/28 

FIELD: measuring equipment.

SUBSTANCE: submersible telemetry device comprises an electrochemical cell 1, two semiconductor diode, a load resistor 3, the switch element 4, one or more analog temperature sensors 5…7 made in the form of two poles, one or more analog pressure sensors 8 and 9, made in the form of two ports, one or more digital vibration sensors 10 and 11, the microprocessor 12, the current source 13. Submersible telemetry device may comprise vibration sensors analog instead of digital vibration sensors 14 and 15. Submersible telemetry device may comprise a microprocessor unit 16, which has in its composition of built-in power source current. Using the cell 1 connected to the first input of the power unit 12 of the microprocessor, digital vibration sensors 10 and 11 and the current source unit 13, the device provides protection from high DC voltage (up to minus 7.5 kV), applied to the device of the megger, extends the functionality capabilities of the device by allowing operation in the submersible rigs, containing as an actuator valve submersible motors, by providing job opportunities to install a submersible asynchronous electric motors with a linear voltage up to 4000 V and in emergency mode with single-phase short circuit on the ground, as well as control stations with frequency controlled without Sin-filter output, improves noise immunity and improves the overall reliability. Using the switching element 4, connected to its first input to the output of the microprocessor unit 12, and output to the series circuit of the load resistor 3 and a semiconductor diode 2.

EFFECT: possibility of transmission of code information by modulating the average power consumption of the unit in time of ground telemetry system at a constant voltage, which increases the reliability of the transmission of the measured parameters and increases noise immunity information channel.
