Nzira yekusiyanisa thermocouple modhi

- 2021-10-19-

Inowanzo shandiswa thermocouples inogona kukamurwa muzvikamu zviviri: standard thermocouples uye isiri-standard thermocouples. Iyo inonzi standard thermocouple inoreva thermocouple iyo thermoelectric simba uye tembiricha zvakatemwa muyero yenyika, iyo inobvumira kukanganisa, uye ine inopindirana mwero indexing table. Iine chitarisiko chekuratidzira chinoenderana chekusarudza. Non-standardized thermocouples haina kunaka seyakajairwa thermocouples maererano nehuwandu hwekushandisa kana kurongeka kwehukuru. Kazhinji, hapana tafura ye indexing inowirirana, uye inonyanya kushandiswa kuyera mune zvimwe zviitiko zvakakosha.

Iwo manomwe manomwe akaenzana thermocouples, S, B, E, K, R, J, uye T, ndiwo thermocouples eakaenderana dhizaini muChina.

Nhamba dze indexing dze thermocouples dzinonyanya S, R, B, N, K, E, J, T zvichingodaro. Zvichakadaro, S, R, B ndedzesimbi inokosha thermocouple, uye N, K, E, J, T ndedzesimbi yakachipa thermocouple.

Izvi zvinotevera tsananguro yeiyo thermocouple index nhamba
S platinamu rhodium 10 yakachena platinamu
R platinum rhodium 13 yakachena platinum
B platinum rhodium 30 platinum rhodium 6
K Nickel Chromium Nickel Silicon
T yakachena mhangura nickel yemhangura
J iron nickel yemhangura
N Ni-Cr-Si Ni-Si
E nickel-chromium mhangura-nickel
(S-mhando thermocouple) platinum rhodium 10-platinum thermocouple
Platinum rhodium 10-platinum thermocouple (S-type thermocouple) isimbi inokosha thermocouple. Iyo dhayamita yewaya mbiri inotsanangurwa se 0.5mm, uye kukanganisa kunobvumidzwa ndeye -0.015mm. Iyo yezita remakemikari inoumbwa yeiyo yakanaka electrode (SP) iplatinum-rhodium alloy ine 10% rhodium, 90% platinum, uye pure platinum yeiyo negative electrode (SN). Inowanzozivikanwa se single platinum rhodium thermocouple. Iyo yenguva refu yekushanda tembiricha yeiyi thermocouple ndeye 1300℃, uye yenguva pfupi yakanyanya kupisa tembiricha ndeye 1600℃.
