ZVIRATIDZO
Yambiro / Attention
Nyatsoteerera kuisa panzvimbo dzinoputika
Mufananidzo 1. Kureba kwakasiyana SET/TSSH2 sensor ine inogadziriswa process yekubatanidza uye nehurefu hwakatarwa uye counter electrode inoshandiswa neSET/TSSHS2 sensor.
GENERAL
SET/TSH2 yakasarudzika nhanho sensor yezvinwiwa zvine tembiricha inosvika 120 °C. Nzvimbo ye sensor inogona kugadziridzwa zviri nyore nekuchinja chinzvimbo cheiyo inogadziriswa R3/4 ″ junction. Inogona kushandiswa seyepamusoro kana yakaderera level detector kana kuona iyo interface pakati pezvinwiwa zviviri zvine chekuita neLabkotec SET- series control unit.
Iyo sensor mudziyo wemidziyo yeboka II, chikamu 1 G uye inogona kuiswa muZone 0/1/2 ine njodzi nzvimbo.
Mufananidzo 2. SET/TSH2 senge yakakwira level alarm mumudziyo wemvura inopisa
CONNETIONS uye INSTALLATION
SET/TSH(S)2 sensor ichaiswa iyo inogadziriswa R3/4” process yekubatanidza kune chikepe chepamusoro.
YAMBIRO! Paunenge uchiisa mumhepo inoputika, cherechedza, kuti iyo yepakati electrode ye sensor yakafukidzwa nezvikamu zvepurasitiki. Panogona kuve nenjodzi yekuchaja kwemagetsi kana zvikamu zvepurasitiki zvikaita kukweshana kana kuyerera kweasingaite midhiya kana zvinhu.
YAMBIRO! Transmitter imba inosanganisira light alloy parts. Paunenge uchiisa mumhepo inoputika, ita shuwa, kuti sensor iripo, kuti haigone kukuvadzwa nemuchina kana kuti isaonekwe kune ekunze kukanganisa.
Iyo tambo pakati pe sensor uye control unit yakabatana kune yakaipa uye yakanaka yekubatanidza mayuniti anoenderana - ona control unit's operation manual. Iyo cable shield uye ese asina kushandiswa waya anoiswa pasi chete pamucheto we sensor pasi pemukati wepasi screw. Kana iyo tambo ichisanganisira nhovo dzakasiyana-siyana, nhovo yekunze inofanira kuiswa pasi pasi pevhu remukati screw uye nhovo dzemukati dzinofanira kubatanidzwa zvakananga kune SHIELD chinongedzo chekutumira. Earthing yekunze nhovo inogonawo kuitwa yakananga kune equipotential pasi, iyo iyo kesi haizobatanidzwe pasi pemukati wepasi screw. Kana iyo sensor yakaiswa munzvimbo inoputika-ine ngozi, iyo yekunze yepasi screw ye transmitter enclosure inofanira kubatanidzwa kune equipotential pasi, sezvainomiririrwa mumufananidzo 3. Iyo base capacitance pakati pezvakatipoteredza uye electrode chimiro inobhadharwa ne external reference capacitor (max. 68 pF) pakati peCref -terminals, iyo inowanzoitwa kare pafekitari, kana chigadzirwa chichayerwa chichizivikanwa. Iyo nhovo yechinhu chekunzwa tambo yakabatana kune GUARD yekubatanidza yeiyo transmitter. Pakuyera yakakwira yekuitisa mvura iyo sensing element tambo yakabatana neCx HIGH yekubatanidza uye kana yakadzikira yekuitisa mvura kuCx LOW yekubatanidza.
Kana iyo yekubatanidza ikashandurwa ipapo kukosha kweiyo referensi capacitor inogona kuchinjwa zvakare.
Iva nechokwadi, kuti kupa voltage yakabatana kune control unit.
Pakuisa iyo SET/TSH(S) 2 sensor munzvimbo inoputika ine njodzi (0/1/2), zvinotevera zviyero zvinoda kuteverwa; TS EN IEC 60079-25 Yakachengeteka masisitimu emagetsi "i" uye EN IEC 60079-14 Kuiswa kwemagetsi munzvimbo dzine njodzi.
KUCHINJISA CHINHU CHINHU
- Shandura SENSE trimmer ye control unit kuti isvike pakunyanyisa wachi.
- Kana iyo yekunzwa ye sensor iri hafu yakanyudzwa mumvura kuti kuyerwa (ona Fig. 4), iyo control unit inofanira kushanda. Kana zvikasadaro, gadzirisa SENSE trimmer zvishoma nezvishoma pokana newachi kusvika painoda switching yasvika.
- Tarisa basa nekusimudza uye kunyudza sensor nguva shoma mumvura.
Maseting akanyanya kuoma anogona kukonzera ma alarm enhema.
IN CASE SENSOR HAISHANDI
Kana iyo sensor iri munzvimbo ine ngozi iyo Ex-classified multimeter inofanirwa kushandiswa uye Ex-standard akataurwa mu4.
SERVICE NEKUGADZIRIRA kunofanira kuteverwa.
- Iyo sensor inofanira kunge yakanyatsobatanidzwa kune control unit.
- The supply voltage pakati pezvibatanidza 1 uye 2 inofanira kuva 10,5…12 V DC.
- Kana iyo sensor inopa voltage yakarurama, batanidza mA-gauge kune sensor circuit maererano neFig. 5 nekubvisa waya nr. 1 kubva th control unit.
Sensor ikozvino mumamiriro akasiyana:
- yakachena uye yakaoma sensor mumhepo 6 - 8 mA
- sensor mumvura 14 - 15 mA
SERVICE NEKUGADZIRIRA
Iyo sensor inofanirwa kugara ichicheneswa pasi uye kuyedzwa kana ichidurura tangi kana kupatsanura uye kana ichiita kugadzirisa kwegore. Pakuchenesa, mushonga wekugezesa wakapfava (semumvura yekuwachisa) nebhurasho rekukwesha zvinogona kushandiswa.
Yakaremara sensor inofanira kutsiviwa neitsva
Sevhisi, kuongorora uye kugadziriswa kweEx-apparatus inofanirwa kuitwa zvinoenderana neTS EN IEC 60079-17 uye EN IEC 60079-19 zviyero.
