Misalai Bimetallic Strip Thermometer

Misali Bimetallic Strip Thermometer?

Misali Bimetallic Strip Thermometer wata wurin da take amfani da siffofin tashin zafi mai zurfi don kula masu zafi. Ana gina shi da fadada metal (kamar steel da brass) da dukkan suka shahara a kan tashin zafi. Idan ana zafi ko hada misalin bimetallic strip, yana kama ko kuma yana kasa saboda tashin zafi na kudanci. Dukunan kamanen ko kasan ya kunshi da tsarin zafi da za a iya nuna ta hanyar pointer a kan scale mai kula.

Ana amfani da Misali Bimetallic Strip Thermometer a duk al'umma da abubuwa saboda cikakken, dayayyansu da kyau, da kuma darajan da ke tsawon. Su iya kula masu zafi daga -100 °C zuwa 500 °C, idan kadan da sunan material da design na bimetallic strip. Su ne ayyukan wurare da ba suka bukata wannan kudin ko kuma circuit mai kula.

Yadda Ake Amfani Da Misali Bimetallic Strip Thermometer?

Tsari da siffar Misali Bimetallic Strip Thermometer ana nuna a bayanan da ake. Misalin bimetallic strip ana gina shi da fadada metal (kamar steel da brass) da dukkan suka shahara a kan tashin zafi. Steel strip ya fi tashin zafi da ita mafi yawa da brass strip, wanda yana cewa yake za a yi kudanci ko kusan ita daidai da brass strip a kan babban tsarin zafi.

Figure: Tsari da siffar Misali Bimetallic Strip

Idan ana zafi misalin bimetallic strip, brass strip ya kudanci mafi yawa da steel strip, wanda yana cewa misalin bimetallic strip ya kama da brass side a kan gabas na curve. Kafin ana hada misalin bimetallic strip, brass strip ya kusan ita mafi yawa da steel strip, wanda yana cewa misalin bimetallic strip ya kama da brass side a kan kusa na curve.

Kamanen ko kasan misalin bimetallic strip ya kunshi da pointer da ake gina a kan ci gaba na strip, wanda yake nuna masu zafi a kan scale mai kula. Ko kuma kamanen ko kasan misalin bimetallic strip ya kunshi da electrical contact, wanda zaka iya bukatar temperature control system ko kuma safety device.

Abun Abubuwan Misali Bimetallic Strip Thermometer

Akwai abubuwan Misali Bimetallic Strip Thermometer biyu a kasuwa: spiral type da helical type. Duka biyu sun amfani da bimetallic strip mai kofin da suka sa sensitivity da compactness na wurin.

Spiral Type Bimetallic Thermometer

Spiral-type bimetallic thermometer ya amfani da bimetallic strip da ake gine a flat spiral coil. Ci gaba na coil ya fara a kan housing, kuma ci gaba na coil ya fara a kan pointer. Idan zafi ya zo ko kuma ya ci, coil ya kama mafi yawa ko kuma kusan ita, wanda yake nuna pointer ya kama a kan circular scale.

Figure: Bimetal thermometer (spiral type)

Spiral-type bimetallic thermometer ya fi tsari da kyau da kuma tsaro da kyau. Amma, akwai wasu limitations, kamar:

Dial da sensor ba su faɗa daga bakinsu, wanda yana cewa wurin da ke da shi yana buƙata a kan medium da za a kula masu zafin.
Accuracy da resolution na wurin ya kunshi da quality da uniformity na bimetallic strip da bonding.
Wurin zai iya shiga mechanical shocks ko vibrations wanda zai iya haƙar errors ko damage.

Helical Type Bimetallic Thermometer

Helical-type bimetallic thermometer ya amfani da bimetallic strip da ake gine a helical coil, kamar spring. Cikin na coil ya fara a kan shaft, kuma ci gaba na coil ya fiye waɗanda ake buƙata. Idan zafi ya zo ko kuma ya ci, coil ya kudanci ko kuma kusan ita axially, wanda yake nuna shaft ya kama. Rotation na shaft zai iya zama a kan pointer through a gear-lever system, wanda yake nuna masu zafi a kan linear scale.

Helical-type bimetallic thermometer ya fi wasu advantages daga spiral type, kamar:

Dial da sensor zai iya faɗa daga bakinsu da amfani da flexible capillary tube, wanda yana buƙata wurin don kula masu zafi a remote ko inaccessible locations.
Accuracy da resolution na wurin ya fi mafi yawa da spiral type saboda displacement da leverage na helical coil.
Wurin ya fi shirin da spiral ga mechanical shocks ko vibrations.

Applications of Bimetallic Strip Thermometers

Bimetallic strip thermometers ana amfani a duk al'umma da abubuwa, kamar:

Temperature control devices: Bimetallic strip thermometers ana amfani don activate ko deactivate cooling or heating system idan zafi ya zo da value. Misali, bimetallic strip ana amfani don switch off electric kettle idan ruwa ya zo da kisa ko turn on fan idan zafi ya zo da room temperature.
Air conditioning and refrigeration: Bimetallic strip thermometers ana amfani don kula da regulate zafi a air ducts, refrigerators, freezers, da sauri. Misali, spiral-type bimetallic thermometer ana amfani a air conditioning thermostat don adjust airflow according to desired temperature.
Industrial processes: Bimetallic strip thermometers ana amfani don monitor da control zafi a industrial processes, kamar oil refining, tire vulcanizing, hot soldering, hot wire heating, da sauri. Misali, helical-type bimetallic thermometer ana amfani a oil burner don regulate fuel supply according to flame temperature.
Temperature measurement and indication: Bimetallic strip thermometers ana amfani don kula da display zafi a liquids, gases, solids, da surfaces. Misali, bimetallic strip thermometer ana amfani don kula water temperature in heating pipe ko surface temperature of engine.

Bimetallic strip thermometers ana da wasu advantages, kamar:

Simple and inexpensive: Bimetallic strip thermometers ana da simple structure da design da suka buƙata manufacture da operate. Ba su buƙata power source ko electrical circuit, wanda yana cewa tsaro da maintenance na wurin ya ci.
Robust and durable: Bimetallic strip thermometers ana gina metallic materials da suka shahara corrosion, wear, da shock. Su iya shiga high temperatures da pressures ba su ci accuracy ko functionality.
Mechanical and analog: Bimetallic strip thermometers ana da mechanical devices da produce analog output proportional to temperature change. Ba su buƙata calibration ko adjustment, da kuma ba su ci electromagnetic interference ko noise.
