Description
При измерении температуры на вращающихс детал х сложным вл етс сн тие показаний.When measuring temperature on rotating parts, it is difficult to read.
Известны устройства бесконтактного измерени температуры вращающихс деталей с использованием емкостных токосъемников и термисторов .Devices for contactless measurement of the temperature of rotating parts using capacitive current collectors and thermistors are known.
Дл повышени точности измерений в предлагаемом устройстве термистор, емкостные токосъемники и сопротивление нагрузки включены последовательно. Кроме того, последовательно токосъемниками включены катушки индуктивности и вс цепь настроена в резонанс с частотой напр жени , питающего измерительную схему. Это уменьшает габариты устройства и позвол ет увеличить длину соединительных проводов .To improve the measurement accuracy in the proposed device, a thermistor, capacitive current collectors and load resistance are connected in series. In addition, inductors are connected in series with current collectors and the whole circuit is tuned to resonance with the voltage frequency feeding the measuring circuit. This reduces the size of the device and allows an increase in the length of the connecting wires.
На чертеже представлена измерительна схема предлагаемого устройства с учетом емкостей соединительных кабелей на землю.The drawing shows the measurement scheme of the proposed device, taking into account the capacities of the connecting cables to the ground.
В качестве датчика температуры использован термистор R, включенный Последовательно сопротивлению „ нагрузки через два емкостных токосъемника Ст. одна пластина которого неподвижна, а втора - вращаетс вместе с деталью. Вс измерительна цепь питаетс от высокочастотного генератора.A thermistor R connected in series to the load resistance through two capacitive current collectors Art. one plate is fixed and the second one rotates with the part. The entire measurement circuit is powered by a high frequency generator.
Рабочий участок температур смещают изменением сопротивлени нагрузки, величина измерительного сигнала пр мо пропорциональна питающему напр жению. Сигнал с вращающейс детали передаетс через два токосъемника.The working temperature section is shifted by the change in load resistance, the magnitude of the measuring signal is directly proportional to the supply voltage. The signal from the rotating part is transmitted through two current collectors.
Дл уменьшени размеров токосъемника Ст и вли ни соедипительных проводов последовательно с токосъемниками включены ка тушки Lfe индуктивности, а вс цепь, составленна емкостью Ст, индуктивностью Lft и емкостью Cj-Се соединительных проводов настроена в резонанс. Сопротивление этой цепи весьма малое по величине и не вли ет на измерительную схему.In order to reduce the size of the current collector St and influence the connecting wires in series with the current collectors, the inductor Lfe is turned on, and the whole circuit made up of the capacitance St, the inductance Lft and the capacitance Cj-Ce of the connecting wires is tuned to resonance. The resistance of this circuit is very small in magnitude and does not affect the measuring circuit.
