Kutentha, kuyeza

Kuloledwa kuyeza kutentha kwa gawo la sensor element ndi:

Ndi Pt100; -200…+550 °C, kutengera zida
Ndi TC: -200…+1200 °C, kutengera mtundu TC, khosi chitoliro kutalika ndi zipangizo

Kutentha kwakukulu kololedwa kwa flange (zinthu AISI 316L) ndi +550 °C, kwakanthawi +600 °C.

Kutentha, kozungulira

Amaloledwa kutentha kozungulira kwa mawaya kapena chingwe, malinga ndi mtundu wa chingwe, ndi:

SIL = silikoni, max. + 180 ° C
FEP = fluoropolymer, max. + 205 ° C

GGD = galasi silika chingwe / zitsulo kuluka jekete, max. + 350 ° C
FDF = FEP wire insulation / braid shield / FEP jekete, max. +205 ° C

SDS = kusungunula waya wa silicone / chishango choluka / jekete la silicone, limapezeka ngati chingwe cha waya cha 2, max. + 180 ° C
TDT = fluoropolymer wire insulation/ kuluka chishango/ fuloropolymer jekete, max. +205 ° C

Musanakhazikitse, onetsetsani kuti njira/makina ndi malo otetezedwa ndi otetezeka kugwira ntchito!

Onetsetsani kuti mtundu wa chingwe ukugwirizana ndi kutentha ndi zofunikira za mankhwala a malo.

Kukonzekera kuyika:

Ndikofunikira kupanga njira yoyenera yoyendetsera / kukhazikitsa kwa seti ya sensa ya multipoint. Za example, sensa imatha kuperekedwa pa ng'oma ya chingwe kapena pa pallet.

a. Chilonda pa ng'oma ya chingwe:
Titha kupereka bala la sensa ya multipoint pa ng'oma yayikulu yokwanira. Mwanjira iyi ndizosavuta kumasula seti ya sensa, pogwiritsa ntchito chitoliro chachitsulo ngati chitsulo chopingasa, kapena benchi yapadera ya ng'oma ngati ilipo pamalopo.
b. Pa pallet ngati koyilo:
Malinga ndi kasitomala kasitomala titha kupereka multipoint sensa yokhazikitsidwanso pa pallet mayendedwe. Pankhaniyi padzakhala pakati thandizo zofunika, mwachitsanzo zopangidwa macheke zidutswa matabwa 2×2” kapena 2×4”. Pamalo oyikapo, payenera kukhala njira zozungulira pallet kuti mutulutse setiyo ku dzenje lopangira. Mabowo a flange atha kugwiritsidwa ntchito ngati pokwezera. Chonde perekani mwatsatanetsatane za zothandizira / zoyika izi kapena funsani malingaliro kuchokera kwa akatswiri athu azamayendedwe.

Magawo oyika:

Pakuyika, kumbukirani kuti MI element yocheperako yopindika ndi 2x ØOD ya chinthucho.
Osapinda nsonga ya chinthu cha MI (utali wa 30 mm kuchokera kunsonga yomverera) ya chinthu cha RTD sensor.
Gwiritsani ntchito mawonekedwe othandizira, ogubuduza kuti mutsegule seti ya sensor. Chonde onani pamwambapa. Ngati magawo ogwirira ntchito apanga bend pa seti ya sensa, mutha kuwawongola mopepuka ndi dzanja.

(MT) = Kutentha kwapakati.

Werengerani kutentha kwakukulu komwe kungatheke pansonga ya sensor:
Example 1 - Kuwerengera nsonga ya RTD-sensor yokhala ndi thermowell

Sensor yogwiritsidwa ntchito pa Zone 0 RTD mtundu wa sensa: WM-9K. . . (RTD-sensor yokhala ndi transmitter yokhala ndi mutu). Sensor yokhala ndi thermowell, m'mimba mwake Ø 9 mm. Kutentha kwapakati (MT) ndi 120 °C Kuyeza kumapangidwa ndi PR electronics head mounted transmitter 5437D ndi chotchinga chapadera PR 9106 B.

Kukana kwamafuta (Rth) kwa sensa ndi = 55 K/W (kuchokera pa Table 3). Kudziwotcha pawokha ndi 0.0233 W * 55 K/W = 1,28 K Kutentha kwakukulu (Tmax) ndi MT + kudziwotcha: 120 °C + 1,28 °C = 121,28 °C Chotsatira mu ex iyiample akuwonetsa kuti, kudziwotcha pansonga ya sensa ndikosayenera.

Mphamvu zoperekedwa ndi PR 9113D ndi (Po) = 40,0 mW (kuchokera ku transmitter Ex-certificate) Kalasi ya kutentha T3 (200 °C) siyenera kupyola. Kukana kwamafuta (Rth) kwa sensa ndi = 100 K/W (kuchokera pa Table 3). Kudziwotcha pawokha ndi 0.040 W * 100 K/W = 4,00 K Kutentha kwakukulu (Tmax) ndi MT + kudziwotcha: 40 °C + 4,00 °C = 44,00 °C Chotsatira mu ex iyiample akuwonetsa kuti, kudziwotcha pansonga ya sensa ndikosayenera.
