Description
Электронные сигнализаторы уровн жидкости, выполненные в виде высокочастотного генератора с емкостной св зью, в анодную цепь которого включено исполнительное реле, не обеспечивает контрол уровни жидкости по двум предельным положени м (верхнему и нижнему }фовн м ).Electronic liquid level detectors, made in the form of a high-frequency generator with capacitive coupling, in the anode circuit of which the actuating relay is connected, do not provide control of the fluid levels by two limiting positions (upper and lower).
Описываемый сигнализатор устран ет этот недостаток применением двух емкостных датчиков, подключенных к одному генератору. с ммарна емкость которых выбрана такой, что срыв и зат гивание генерации происходит в результате суммарного изменени емкости датчиков , обеспечиваетс работа сигнализатора в релейном режиме при двух предельных положени х контролируемого уровн .The described alarm eliminates this disadvantage by using two capacitive sensors connected to one generator. The millimeter capacity of which is chosen such that the breakdown and delay of generation occurs as a result of the total change in the capacitance of the sensors, the operation of the detector in the relay mode is provided at two limit positions of the monitored level.
На чертеже показана схема включени .The drawing shows the wiring diagram.
В сосуде 1, заполн емом жидкостью, размещены емкостные датчики нижнего 2 и верхнего 3 уровн . Датчики подключены к одному генератору 4, управл ющему работой показывающих и регулирующих органов установки (на чертеже не показаны).In the vessel 1 filled with liquid, capacitive sensors of the lower 2 and upper 3 levels are placed. The sensors are connected to one generator 4, which controls the operation of the indicating and regulating organs of the installation (not shown in the drawing).
Предмет изобретени Subject invention
Электронный сигнализатор уровн жидко/гти, выполненный в виде высокочастотного генератора с емкостной св зью, в анодную цепь которого включено исполнительное реле, о т л и ч а ю uj, и и с тем. что, с целью обеспечени работы сигнализатора в релейном режиме при двух предельных положени х контролируемого уровн , в нем применено два емкостных датчика, подключенных к одному генератору, емкость которых выбрана такой, что срыв и зат гивание генерации происходит в результате суммарного изменени емкости датчиков.An electronic liquid level / gti level indicator device, made in the form of a high-frequency generator with capacitive coupling, in the anodic circuit of which an actuating relay is connected, which is connected to the j uj, and so on. that, in order to ensure the operation of the detector in the relay mode at two limiting positions of the monitored level, it used two capacitive sensors connected to one generator, the capacity of which was chosen such that the breakdown and generation delay occurs as a result of the total change in the capacitance of the sensors.
