PR293 Series Nanovolt Microhm Thermometer

Kutsimikizika kwakukulu kwa 7 1/2

Integrated thermocouple CJ compensator

Njira zingapo zoyezera

PR291 mndandanda wa ma thermometers a microhm ndi PR293 mndandanda wa nanovolt microhm thermometers ndi zida zoyezera molondola kwambiri zomwe zimapangidwira kutentha kwa metroloji.Ndioyenera kuchita zinthu zambiri, monga kuyeza kwa kutentha kwa sensa ya kutentha kapena deta yamagetsi, kuyesa kufanana kwa kutentha kwa ng'anjo za calibration kapena malo osambira, ndi kupeza chizindikiro cha kutentha ndi kujambula njira zingapo.

Ndi miyeso yoyezera bwino kuposa 7 1/2, poyerekeza ndi ma multimeter olondola kwambiri a digito, omwe akhala akugwiritsidwa ntchito kwambiri pazanyengo kwanthawi yayitali, pali mapangidwe ambiri okhathamiritsa malinga ndi mitundu, ntchito, kulondola, komanso kugwiritsa ntchito mosavuta kupanga njira yosinthira kutentha kukhala yolondola, yabwino komanso yachangu.

Mawonekedwe

• Kukhudzika kwa 10nV / 10μΩ

Mapangidwe opambana a ultra-low phokoso amplifier ndi low ripple power supply module amachepetsa kwambiri phokoso lowerengera la loop ya siginecha, motero amakulitsa chidwi chowerenga kukhala 10nV/10uΩ, ndikuwonjezera bwino manambala owonetsera pakuyezera kutentha.

• Kukhazikika kwabwino kwapachaka

PR291/PR293 ma thermometers angapo, kutsatira mfundo yoyezera chiyerekezo komanso zodzikongoletsera zokhazikika, zimakhala ndi kutentha kochepa kwambiri komanso kukhazikika kwapachaka.Popanda kutengera kutentha kwanthawi zonse, kukhazikika kwapachaka kwa mndandanda wonse kumatha kukhala kwabwinoko kuposa ma multimeter omwe amagwiritsidwa ntchito kwambiri 7 1/2.

• Integrated multi-channel low-noise scanner

Kuphatikiza pa tchanelo chakutsogolo, pali 2 kapena 5 zodziyimira pawokha zoyeserera zogwira ntchito zonse zomwe zimaphatikizidwa pagawo lakumbuyo molingana ndi mitundu yosiyanasiyana ya ma thermometers a PR291/PR293.Njira iliyonse imatha kukhazikitsa mtundu wa chizindikiro choyesera, ndipo imakhala ndi kusinthasintha kwakukulu pakati pa ma tchanelo, kotero kuti kupeza ma data angapo kumatheka popanda kusintha kulikonse.Kuonjezera apo, mapangidwe otsika phokoso amatsimikizira kuti zizindikiro zolumikizidwa kudzera muzitsulo sizidzabweretsa phokoso lowonjezera lowerengera.

• Kulipira kolondola kwambiri kwa CJ

Kukhazikika ndi kulondola kwa kutentha kwa CJ kumatenga gawo lofunikira pakuyezera ma thermocouples olondola kwambiri.Mamita olondola kwambiri a digito omwe amagwiritsidwa ntchito nthawi zambiri amafunikira kuphatikizidwa ndi zida zapadera za CJ zolipirira muyeso wa thermocouple.Gawo lodzipatulira la High-precision CJ compensation module limaphatikizidwa mu PR293 series thermometers, kotero kuti cholakwika cha CJ cha njira yomwe imagwiritsidwa ntchito bwino kuposa 0.15 ℃ popanda zotumphukira zina zitha kuzindikirika.

• Kutentha kwakukulu kwa metrology ntchito

PR291/PR293 mndandanda wa ma thermometers ndi chida choyesera chapadera chomwe chimapangidwira makampani otentha a metrology.Pali njira zitatu zogwirira ntchito, kutsata njira imodzi, ndi kuyeza kwa kusiyana kwa kutentha, komwe muyeso woyezera kutentha umatha kusanthula kutentha kwamitundu yonse yazida zotentha zokhazikika.

Poyerekeza ndi ma multimeter akale a digito, mitundu ya 30mV yoyezera ma thermocouples amtundu wa S ndi mtundu wa 400Ω wa PT100 muyeso wa platinamu amawonjezedwa.Ndipo ndi mapulogalamu osinthika osinthika a masensa osiyanasiyana a kutentha, masensa osiyanasiyana (monga ma thermocouples, ma thermometers okhazikika a platinamu, ma thermometers a platinamu kukana ndi ma thermocouples ogwirira ntchito) amatha kuthandizidwa, ndipo chidziwitso cha satifiketi kapena kuwongolera kungatchulidwe kuti tifufuze. kutentha kwa zotsatira za mayeso.

• Ntchito yosanthula deta

Kuphatikiza pa ma data osiyanasiyana oyesera, ma curve ndi kusungirako deta amatha kuwonetsedwa, zenizeni zenizeni zenizeni / zochepa / mtengo wapakati, mitundu yosiyanasiyana ya kutentha kwa kutentha imatha kuwerengedwa, ndipo deta yochuluka komanso yocheperako imatha kulembedwa kuti ithandizire kusanthula kwachidziwitso. pa malo oyesera.

• Mapangidwe onyamula

Mamita olondola kwambiri a digito omwe amagwiritsidwa ntchito m'ma laboratories nthawi zambiri amakhala akulu komanso osasunthika.Mosiyana ndi izi, ma thermometers a PR291/PR293 ndi ochepa mu voliyumu komanso kulemera kwake, komwe ndi koyenera kuyezetsa kutentha kwapamwamba m'malo osiyanasiyana patsamba.Kuphatikiza apo, kapangidwe ka batire ya lithiamu yokhala ndi mphamvu yayikulu imapangitsanso kuti ntchito ikhale yosavuta.

Tebulo losankhira zitsanzo

Mafotokozedwe amagetsi

Zindikirani 1: Kutengera njira yoyezera mawaya anayi kuti muyeze kukana: kuchuluka kwa 10KΩ ndi 0.1mA, ndipo kusangalatsa kwamitundu ina ndi 1mA.
