Abstract[EN]The invention relates to a gas/liquid separator comprising a capacitive level sensor, which is particularly suitable for systems that employ reduced volumes of fluids at high pressures. The inventive separator consists of a metal part (1) comprising a borehole which is closed at the lower end thereof, such as to form a container (2). The aforementioned container comprises at least one gas inlet (8), one liquid outlet (9) and one gas outlet (10). According to the invention, a cooling system, in the form of a Peltier cell that is in contact with the walls of the metal part (1), generates the condensation of the liquid which is collected at the bottom of the container (2) until the introduction of a probe (4) which is electrically isolated from the system and which forms an electric condenser with the walls of the part (1). The capacity of the condenser varies according to the level of liquid in the container (2). In addition, a frequency signal is generated by means of an oscillator system and received by a microprocessor (13) which forms an output signal that is proportional to the response from the sensor and, consequently, the height of the liquid in the container (2).
[ES]Separador gas-líquido con sensor de nivel capacitivo, de especial aplicación al sistemas donde se trabaja con volúmenes de fluidos reducidos y altas presiones, que comprende una pieza (1) metálica que cuenta con un taladro cerrado inferiormente, constituyendo así un depósito (2 ). Dicho depósito cuenta con al menos una entrada de gases(8), una salida de líquidos (9) y una salida de gases (10). Un sistema de refrigeración, materializado en una célula Peltier en contacto con las paredes de la pieza metálica (1) provoca la condensación del líquido, siendo éste recogido en el fondo del depósito (2) , hasta donde se introduce una sonda (4) aislada eléctricamente del sistema.
