Transduseri na Yauwa

Bayani: Mai hawa na tsarin jama'a shi ne wani babban abincin kimiyya wanda yana aiki don in yi gajarta da hawa da kuma kawo a kan abubuwa masu ma'ana kamar yanayi, kyauko, ko kuma shiga. Mafi girman mihirinsa shine in taimaka wa aiki mai zama a gajarta hawa. Zanen bayanin da ke cikin mai hawa na tsarin jama'a shi shine in samun hawa da kuma kawo a kan abubuwa masu ma'ana.

Mahimmanci na Mai Hawa na Tsarin Jama'a Shi

• Mai hawa na tsarin jama'a shi ya ba da hawa a matsayin muhimmin abu.

• Abincin kimiyya suna kawo hawa a kan abubuwa masu ma'ana.

• Sunamfuta su don in gajarta hawa da kuma sauran al'amari a kan abubuwa.

Elementin Mai Gajarta

Elementin mai gajarta da ake amfani a kan mai hawa na tsarin jama'a shi ya kamata a taka muhimmiyar al'amari a matsayin hawa. Misali, a kan mai hawa na tsarin jama'a shi, platinum ta aiki a matsayin elementin mai gajarta. Muhimman al'amurun da ke cikin elementin mai gajarta shine:

• Elementin mai gajarta ya ba da hawa a matsayin muhimmin abu.

• Yana kasancewa a matsayin hawa.

• Elementin mai gajarta ya kamata a taka muhimmiyar al'amari a matsayin hawa.

Abunawa na Mai Hawa na Tsarin Jama'a Shi

Mai hawa na tsarin jama'a shi suna kungiyar a kan abunawa biyu:

Ayyuka Mai Gajarta Masu Lamiya

A wannan abunawa, elementin mai gajarta yana lami da kayan hawa. Tashin hawa yana faruwa a kan abun hawa daga wani abu zuwa wani abu baki daya.

Ayyuka Mai Gajarta Ba Da Lamiya

A wannan abunawa, elementin mai gajarta ba a lami da kayan hawa. Amma, suna neman tashin hawa a kan abun hawa daga wani abu zuwa wani abu baki daya.

Mai hawa na tsarin jama'a shi suna kungiyar a kan abunawa biyu:

• Negative Temperature Coefficient (NTC) Resistance Thermometers: Wadannan suna amfani da su don in gajarta hawa. Idan hawa ya zama, resistance ta NTC thermistor ya koma. Wannan al'amurin yana taimaka wa a gajarta hawa da ma'ana.

• Positive Temperature Coefficient (PTC) Resistance Thermometers: PTC thermometers suna amfani da su don in kontrola current. Idan hawa ya zama, resistance ta PTC thermistor ya ci. Wannan al'amurin yana taimaka wa a kontrola flow of electric current a kan abubuwan.

• Operating Principle of Resistance Thermometers: Metals suna da al'amuran da resistance su yana faruwa a kan hawa. Resistance thermometers suna amfani da wannan al'amurin don in gajarta hawa. Platinum shine elementin mai gajarta a kan high - precision resistance thermometers. Saboda platinum's stable and predictable resistance - temperature relationship, wadannan thermometers su iya gajarta hawa da ma'ana. Ta haka, idan ake gajarta resistance ta platinum, za a iya gajarta hawa da ma'ana, wanda yake taimaka wa a amfani da resistance thermometers a kan abubuwan.

Thermocouples: Thermocouple shine wani babban abincin kimiyya wanda yana aiki don in kawo hawa a kan energy. Yana aiki a kan abun hawa da kuma kawo a kan abubuwa masu ma'ana. Idan wani abu da wani abu suna lami, wanda yake aiki shine Seebeck effect. Idan hawa ya faru, voltage ya faru a kan junction. Wannan voltage shine directly proportional to the temperature difference between the junction and a reference point. Wannan linear relationship between the generated voltage and temperature allows thermocouples to be highly effective in accurately measuring temperature. Suna amfani da su a kan abubuwan industrial, scientific, and domestic applications, where precise temperature monitoring and control are crucial, such as in furnaces, ovens, and industrial process control systems.

Integrated Circuit Temperature Transducer: Integrated circuit (IC) temperature transducer shine wani babban abincin kimiyya wanda yana aiki don in gajarta hawa. Wadannan suna amfani da combination of a temperature - sensing element and an electronic circuit to measure temperature. Wadannan type of transducer is characterized by its linear response, which simplifies the process of converting the sensed temperature into an electrical output that can be easily interpreted. Amma, one of the notable drawbacks of the integrated temperature transducer is its relatively narrow operating range. It typically functions within a temperature span of 0°C to 200°C. This limited range restricts its applicability in certain high - temperature or low - temperature environments where broader temperature coverage is required.

Despite this shortcoming, IC temperature transducers are widely used in numerous applications such as consumer electronics, where their compact size, linearity, and relatively simple interfacing make them a preferred choice for temperature monitoring within the specified temperature range.movement of the substance. Non - contact type transducers can be further sub - categorised, with one example being the thermistor. A thermistor is a type of resistor whose resistance changes with temperature. Its resistance is measured by passing a small, measured direct current, which in turn causes a voltage drop across the resistance.
