Изобретение относитс  к области контактной термометрии.This invention relates to the field of contact thermometry.

Известны устройства дл  бесконтактного измерени  параметров В|ра1дающихс  деталей машиН, (В которых аналогом измер емого параметра  вл етс  величина ем-кости варикапа , управл емое напр жение на который подаетс  через усилитель от датчика, расположенного на вращающейс  детали. Варикап св зан с ротором вращающегос  конденсатора , статорна  обкладка которого подключена к стационарному измерителю емкости.Devices are known for contactless measurement of the parameters B | of the existing machine parts, (in which the analogue of the measured parameter is the value of the capacitance of the varicap, the controlled voltage applied to the amplifier through a sensor located on the rotating part. The varicap is connected to the rotating rotor a capacitor, the stator plate of which is connected to a fixed capacitance meter.

Однако известные устройства нуждаютс  в периодических тарировках вследствие возможных сдвигов «нул  и коэффициента передачи .However, the known devices need periodic calibrations due to possible shifts of "zero and transmission coefficient.

С целью Повышени  точности измерени  в предлагаемом устройстве с варикапом, вход щим в подвижной блок, и вращающимс  конденсатором введен вар-икаи, в управл е .мую цепь «oTQporo включены последовательно преобразователь емкости в напр жение и регистрирующее устройство.In order to improve the measurement accuracy in the proposed device with a varicap included in the movable unit and a rotating capacitor, a var-ikai is inserted into the control circuit of the "oTQporo" capacitor in series in the voltage and the recording device are connected in series.

На чертеже показана схема -предлагаемого устройства.The drawing shows the scheme of the proposed device.
