Pressure sensor for a gas-filled cylinder
A pressure sensor for a gas-filled cylinder, which comprises a body from which a connector protrudes for coupling to an opening for filling a gas-filled cylinder with gas, a first through hole which passes through the connector and the body and a second hole which connects the first through hole to a sensor element which is connected electrically to at least one electronic board for processing a signal that can be detected by the sensor element.
1. A pressure sensor for a gas-filled cylinder comprising:
a body having a connector for coupling to an opening for filling the gas-filled cylinder with gas, wherein the connector protrudes from the body,
a sensor; and
at least one electronic board, wherein the at least one electronic board is configured to process a signal detected by said sensor,
wherein a first through hole that passes through said connector and said body and a second hole that connects the first through hole to the sensor, which is connected electrically to the least one electronic board.
2. The pressure sensor according to claim 1 , wherein said connector is threaded complementarily to the opening for filling said gas-filled cylinder.
3. The pressure sensor according to claim 1 , further comprising a safety plug which is adapted to close said first through hole on an opposite side with respect to said connector.
4. The pressure sensor according to claim 1 , wherein said first through hole and said second hole are provided in a perforated screw element to be inserted transversely into said body.
5. The pressure sensor according to claim 3 , wherein said safety plug is inserted into a head of said screw element with which said screw element protrudes from said body.
6. The pressure sensor according to claim 1 , wherein the pressure sensor is adapted to interact with a valve, wherein the valve is adapted to prevent a passage of gas in output from said gas-filled cylinder.
7. The pressure sensor according to claim 6 , wherein said valve is installed inside said first through hole between said safety plug and said second hole.
8. The pressure sensor according to claim 6 , further comprising a needle element which is accommodated in said first through hole and is adapted to be pushed against said valve which is present at an inlet of a channel for filling the gas-filled cylinder with gas.
9. The pressure sensor according to claim 1 , further comprising a screen which is connected electrically to said at least one electronic board, and which is adapted to show at least a pressure value processed by said board.
10. The pressure sensor according to claim 1 , further comprising at least one LED which is connected electrically to said at least one electronic board.
