JJB30 Taputapu Ine Mamao Methane Taiaho Whakamahinga-Maina

Ko te taputapu ine mamao methane laser e whakamahia ana e te maina JJB30 kua hangaia i runga i te hangarau taputapu optoelectronic matua o tā mātou kamupene. E whakamahi ana i te meka he pānga mimiti te hau methane ki tētahi roangaru motuhake o te laser, ā, ko te kaha mimiti e pā ana ki te kukū o te hau methane (e ai ki te ture Lambert-Beer).

He taputapu tirotiro hau ringaringa tēnei, e whakamahia ana mō te ine mamao i ngā hau methane me ngā hau kei roto te methane (hau māori, hau rite rānei). Mā te tuku i te hihi laser ki te pūwāhi tirotiro, ka taea te ine tere i te kukū hau methane i roto i te tawhiti o te 0 ki te 30 mita. Mā te tuku i te hihi laser ki te pūwāhi ūnga (pērā i te kokonga o runga o te maina waro, ngā paipa hau, ngā tuanui, ngā pakitara, ngā papa, te whenua, me ētahi atu) kātahi ka kitea te tohu o te laser e whakaatahia ana mai i te pūwāhi ūnga, ka taea te ine i te kukū hau methane i roto i te papatipu hau e tohatohahia ana i waenga i te taputapu me te pūwāhi ūnga.

1. He mahi tā te taputapu ine mamao ki te ine i te methane

te arotahi

2. Kei te taputapu ine mamao te mahi whakaoho i runga ake i te rohe.

3. Ko te uara whakaatu o te taputapu ine mamao he tohu whaimana mati-rima

pānui, e whakaatuhia ana i te ahua matihiko, ā, ko te taumira he 1 ppm·m

1. Awhe telemetry whai hua: 0m – 30m.

2. Awhe ine: (0 – 6400) ppm·m; Ko te hau methane i inehia

ko te kukū he (0 – 4)% CH4, ā, ko te roa o te ara e whiti ana te taiaho

e 0.16 mita te hohonu e puta ana i roto i te hau methane.

3. Hapa taketake: (0 – 6400) ppm·m, uara pono ±10%.

4. Me taea e te taputapu te whakatakoto i tētahi pūwāhi whakaoho i roto i te whānuitanga o

(100 – 6400) ppm·m, ā, ka puta he whakaoho oro ina nui haere te hau methane

i kitea.

5. Tikanga whakaatu: Whakaaturanga karaihe wai.

6. Taumira whakaatu: Te kukū o te methane: 1 ppm·m, whakaaturanga tawhiti:

0.01m.

7. Wā whakahou raraunga whakaatu: ≤ 1 hēkona.

8. Te taumata tiaki o te whare herehere: IP54.

9. Kaua e iti iho i te 8 hāora te roa o te wā mahi tūtatari.

10. Ārai-pahūtanga: Tiwhikete ārai-pahūtanga Exib IMb
