7 - DESCRIPTION OF THE INVENTION. As can be inferred from the accompanying drawings and integral parts of this report, the Electro-Electronic Device for Intelligent Monitoring of Linear Displacement Valves, (!), Is characterized by a resin encapsulated sensor module (2); solenoid valve body (3) with electrical connection (4).

The operating principle of the sensor (2) is based on actuator position detection, which is mechanically connected to the actuator shaft (5), in turn repeating the up and down movement of the pneumatic actuator when pressurized.

The drive shaft (5), as the valve opens, penetrates the core of a solenoid coil (6), changing the electromagnetic field formed inside it, highlighting that an electronic circuit converts the variation of this electromagnetic field into a signal that is proportional to the displacement of the trigger within the coil (6).

Moreover, it is noteworthy that to increase the sensitivity and accuracy of detection, the coil (6) is segmented into 5 windings, which are monitored via a high speed muMplex electronic circuit and in addition, it is worth noting that the axis (5) The actuator has a phenolic core capable of causing a more significant variation in the electromagnetic field, allowing the sensor (2) to detect movements up to 0.2 mm with accurate repeatability.

The signal is then converted to digital and widely manipulated by the same processor that commands all sensor functions (2).

The sensor (2) is provided with many local signaling capabilities of the valve position, among them the mechanical position signaling, carried out by a yellow indicator (7) inside the transparent cap on the sensor top (2).

Internally the sensor has a spring (9) which rests on the mechanical signal (8) and the drive shaft (5), transmitting the upward movement of the axis to the local signal (8), noting that this signal (8) appears inside the transparent cover indicating that the valve is open regardless of the travel of the actuator shaft (5), providing accurate signaling even if the stroke is 5 or 50 mm.

In a second feature of local valve position signaling, the seven Position Signal (10) stands out, which indicate by the color of light emitted the open or closed position of the valve, clearly visible at a distance of up to 15 meters from various positions.

In yet another local signaling feature, this sensor (2) is equipped with 3 magnetic buttons (11), which provide a higher degree of protection, making the sensor (2) more immune to liquid penetration. Pushbuttons (11) allow you to program all sensor functions (2) and help prevent unauthorized persons from changing the settings as they have a sequence and magnetic polarization of the drives.

Also, it is noteworthy that this sensor (2) is supplied with a magnetic keychain that has two magnetic "N" North (12) and "S" South (13) magnetic poles to promote the actuation of the magnetic buttons.

Another signaling provided by this sensor (2) is the signaling display (14), the main communication portal for both the user and technicians when the product is to be installed for the first time or during its maintenance.

This signaling display (14) has the characteristic of being an open or closed valve position indicator, having a local flag, yellow, which moves according to the valve movement. when open, the positioner remains fully displayed at the top of the display (14) and when closed, the positioner is fully retracted at the bottom of the display (14).

This display (14) further indicates the number of assembly cycles performed by the "valve / actuator" assembly, according to a "BASE 10" engineering notation, indicating the number of cycles, ie XY * 10 Z XY * EZ.

It also has a Partial Cycle Counter, responsible for assisting in the preventive maintenance of the system, and allowing the user to determine the number of cycles in which a preventive maintenance alarm is triggered, to replace worn parts / moving parts such as , diaphragms, gaskets, seals, stops and others ..

It also has a total cycle counter or life cycle counter, which indicates the number of maintenance-free total cycles that the assembly has undergone, even after several partial counter resets, and aims to identify the system life, and Its maximum capacity is 99,109, and it can be reset via the main menu to monitor a new assembly or relocate the sensor (2) to another valve.

It is provided with an error indicator which, when an error occurs that the sensor diagnostics system (2) detects this occurrence will be signaled by the use of flashing red LEDs on the display (14).

In yet another operation and task provided by this device (1), it is worth highlighting the monitoring of the maneuver time in which the sensor (2) is provided with an intelligent function that "learns" with the first maneuvers of the valve, and stores the average opening and closing time of the valve, and when this time exceeds the individually pre-programmed limit for each valve, it generates an alarm indicating a tendency of abnormality, noting that if the process has a lot of variability and uses several fluids, If the opening / closing time is different, the percentage of variation allowed by the alarm can be increased or decreased, or even inhibited.

In order to increase the reliability of the system incorporating this sensor (2), it is equipped with a circuit capable of detecting if a short circuit occurs in the discrete outputs of the sensor (2), indicating problems with the electrical connection, connections or electronic module of the sensor. P LC, where an alarm is generated by the display (14) and fault displays.

In another operation, the sensor (2) permits monitoring of the internal solenoid coil (6), in which the sensor diagnostic system (2) monitors the integrity of the coil (6) of the solenoid valve incorporated in the sensor (2). In the event that a short circuit or breakage of the coil wire (6) occurs, the sensor (2) generates an alarm, signaling through the display (14) and the fault screens.

It also has a "Sleep" energy saving system, noting that although the display (14) and the position indicator lights consume low power, the settings menu allows them to be turned off if there is no button actuation ( 11) magnetic, aiming at energy saving or where the light signaling does not provide gain to the system operation.

Finally, it is noteworthy that the sensor (2) has a unique "Auto-Teach" setting mode, that through a simple sequence of activation of the magnetic buttons (11), the sensor (2) self-calibrates, regardless of whether it is connected. or not to the control system, ttFLC "or" Individual Network ", making the setup process very fast and effective.

8 - CONCLUSION.

From all that has been described and illustrated, this is an Electro-Electronic Device for Intelligent Monitoring of Linear Displacement Valves, (1) which fits perfectly within the rules governing the Invention Patent and must be completed. important gap in the market, but still offering the advantages described in the corresponding paragraph, deserving for what was exposed and as a consequence, the respective privilege.
