Amfani Da Transducer Mai Rausa
Transducer mai rausa suna da muhimmanci a fannoni da dama saboda yadda suke kawo abubuwa masu inganci zuwa al'amuran tushen ta ƙaramin ƙaramin rausa. Ga wasu manyan amfani da su:
Potentiometers
Duk potentiometers translational da rotatory sun fiye da misalai na transducer mai rausa. A wasu wannan devices, idan takarda na wiper (shiga contact) ya ƙirƙira, tsari na al'adun tsari da tushen ya haɗa ya ƙirƙira. Saboda rausa ya ƙaramin tsari (kamar yadda ake bayyana R =ρL/A), wannan ƙaramin tsari ya zama da ƙaramin rausa. Wannan halaye ya ba potentiometers kyau don cewa hanyoyin tsakiyar, kamar yadda ake cewa hanyoyin tsakiyar linear a cikin potentiometers translational ko angular rotation a cikin potentiometers rotatory. Su ake amfani da su a fannoni da dama kamar joysticks for gaming consoles, position sensors in robotic arms, and volume control knobs in audio equipment.
Strain Gauges
Strain gauges sun amfani da piezoresistive effect, inda rausa na semiconductor ko metallic material a cikin gauge ya ƙirƙira idan ake ƙirƙira mechanical strain. Idan force na gaba ya ƙirƙira deformation ko strain a kan material na strain gauge, yana ƙirƙira tsarin fisikinsu a ƙarfin atom, wanda ya ƙirƙira electrical resistance. Ta haka, tare da ƙaramin ƙaramin rausa, engineers sun iya cewa abubuwa kamar pressure, force, and displacement. Strain gauges suna amfani da su a fannoni da dama kamar aerospace for aircraft structural health monitoring, in automotive engineering for measuring forces on engine components, and in civil engineering for assessing the stress on bridges and buildings.
Resistance Thermometers
Ko kuma ake kira Resistance Temperature Detectors (RTDs), resistance thermometers sun ƙungiyar da al'adun rausa na metals ya ƙirƙira ta hanyar ƙaramin jiki. Metals suna da ƙaramin jiki-resistance characteristics, kuma tare da ƙaramin resistance-temperature relationship, wannan devices sun iya cewa jiki da dukkar. RTDs suna fiye a fannoni da dama idan an bukata cewa jiki da dukkar, kamar a industrial manufacturing processes, scientific research laboratories, and climate-controlled environments. Su na stability, repeatability, and wide measurement range, wanda ya ba su kyau don tasks na temperature sensing.
Thermistors
Thermistors sun ƙungiyar da al'adun temperature coefficient of their material varies significantly with temperature. Unlike many metals, thermistors typically have a negative temperature coefficient (NTC). This means that as the temperature increases, the resistance of the thermistor decreases in an inversely proportional manner. Thermistors are extremely sensitive to temperature changes, allowing for rapid and accurate temperature measurements. They are commonly used in applications where compact size, high sensitivity, and quick response times are required, such as in thermostat controls for household appliances, temperature sensors in computer cooling systems, and medical devices for monitoring body temperature.
In essence, the diverse ways in which the resistance of metals and other materials can change in response to physical phenomena form the foundation of resistive transducer applications. This unique property enables the accurate measurement and monitoring of a wide range of physical quantities, making resistive transducers indispensable components in modern measurement and control systems.
