Description

Известны электропневматические датчики температуры, дающие информацию в виде двух коротких сигналов, врем  между которыми пропорционально контролируемой температуре.Electropneumatic temperature sensors are known that provide information in the form of two short signals, the time between which is proportional to the temperature being monitored.

Предлагаемый электропневматнческий датчик отличаетс  от известных тем, что насос датчика выполнен в виде подпружиненного сильфоиа, св занного с сердечником соленоида, что дает возможность работать датчику но запросу с использованием одних и тех же нроводов дл  посылки запроса и получени  информации.The proposed electro-pneumatic sensor differs from the known ones in that the sensor pump is designed as a spring-loaded sylphia connected to the core of the solenoid, which makes it possible to operate the sensor on demand using the same wires to send the request and receive information.

Второе отличие состоит в том, что дл  герметизации газового объема второй конец капилл ра соединен с камерой, котора  обладает малой объемной жесткостью.The second difference is that in order to seal the gas volume, the second end of the capillary is connected to the chamber, which has low volumetric rigidity.

На чертеже показано устройство электропневматического датчика.The drawing shows the device of the electropneumatic sensor.

Предложенный электропневматический датчик работает по запросу . Дл  получени  информации в . датчик посылаетс  импульс тока (запрос), после которого датчик выдает в ту же линию два ответных импульса, врем  между которыми зависит от контролируемой температуры . В основу работы датчика ноложена зависимость в зкости газов от температуры. Ниже приводитс  описание электропневматического датчика. В корпусе / помещена упруга  камера, выполненна  в виде м гкого сильфона 2, соединенна  с  корем 3 электромагнита 4. При подаче запращивающего импульса на зажимы датчика электромагнит раст гивает сильфон 2, который наполн етс  газом, поступающим через клапан 5 из упругой камеры 6, обладающей минимальной объемной жесткостью. После прекращени  запрашивающего импульса сильфон 2 под действием пружины 7 сжимаетс . Газ из сильфона продавливаетс  через рабочую часть датчика, воспринимающую контролируемую температуру, в камеру 6. На пути прохождени  газа помещен капилл р 8, сопротивление которого прохождению газа увеличиваетс  при нагреве . Сильфон 2 в зависимости от температуры будет сжиматьс  быстрееThe proposed electro-pneumatic sensor works on request. For information c. The sensor sends a current pulse (request), after which the sensor sends two response pulses to the same line, the time between which depends on the monitored temperature. The basis of the sensor operation is the dependence of the viscosity of gases on temperature. The following is a description of an electropneumatic sensor. An elastic chamber, made in the form of a soft bellows 2, connected to the core 3 of the electromagnet 4 is placed in the housing /. When applying a pick pulse to the sensor terminals, the electromagnet stretches the bellows 2, which is filled with gas coming through valve 5 from minimum bulk stiffness. Upon termination of the requesting pulse, the bellows 2 is compressed by the action of the spring 7. Gas from the bellows is forced through the working part of the sensor, which senses the controlled temperature, to chamber 6. A capillary tube 8 is placed on the gas path, the resistance of which to the gas passage increases during heating. The bellows 2 will compress faster depending on the temperature.
