te Raupapa DPH he raina motuhake o ngā pūoko pēhanga i hangaia mō ngā tono e hiahia ana ki te kohikohi raraunga taumira teitei me te aroturuki tonu. Ahakoa e arotahi ana te raupapa DPS ki te arorau whakawhiti, ko te Raupapa DPH kua arotauhia mō āna Putanga Analog (1-5V, 4-20mA rānei), e whakarato ana i tētahi tohu rārangi e ōrite ana ki te pēhanga kua kitea mō ngā PLC, ngā pūnaha SCADA, me ngā kaiwhakahaere tere-tiketike.
Ko ēnei pūoko te paerewa ahumahi mō ngā takahuri urupare tika i roto i te mana taurite me te whakamātautau turuturu aunoa.

Āhuatanga matua
1. Tohu Anaro Raina-Tiketike
Ka whakamahia e te raupapa DPH he diaphragm silicon kounga teitei e whakarite ana i te putanga rārangi me te iti o te pekapeka (±0.2% FS). Nā tēnei ka tino pai mō te whakahaere tukanga ina kore e ranea te "tata ki te rawaka".
2. Aroturuki Whakaaturanga-Rua
Ahakoa ko tana mahi matua he tuku oro ā-oro, kei roto i te DPH he whakaaturanga mati-4 kanapa.
- Whakaaturanga Matua (Kakariki/Whero): E whakaatu ana i te uara pēhanga o nāianei.
- Whakaaturanga-Iti (Karaka): E whakaatu ana i te uara "Paepae" me te "Tihi/Raro" i te wā kotahi.
3. Mahi Tauine Whakauru
Ka taea e te kaiwhakamahi te whakawhanui i te putanga anaro kia ōrite ki te tono. Hei tauira, ka taea e koe te whakatakoto i te putanga 5V kia tīmata i te 0.7 MPa hei utu mō te awhe 1.0 MPa katoa, kia taea ai te taumira teitei ake i roto i tētahi matapihi mahi motuhake.
4. Whakatikatika Kore me te Pupuri Tino
Mā te pūoko ka taea te whakamahi i te "Tautuhi-Kore" hei whakatikatika i ngā huringa pēhanga o te hau. Mā ngā mahi pupuri tihi me raro ka taea e te pūoko te hopu me te whakaatu i ngā pikinga pēhanga teitei, iti rānei i tuhia i te wā o te huringa.
Te Tukatuka Tohu me te Whakaurunga
Kua hangaia te raupapa DPH hei "kanohi" mō tō pūnaha whakahaere. Mā te whakaputa i te tohu 4-20mA, ka whakakorea ngā raruraru haruru hiko i runga i ngā taura roa, kia tika ai te whakaaturanga o te āhua hau i te PLC.
Te Hurihanga Tono Noa:
- Source: Ka pupuri te Kaiwhakahaere AR/BR i te pēhanga taketake.
- Te kitenga: Ka aroturukihia e te Pūoko DPH te pēhanga raina tuturu.
- Urupare: Ka tukuna e te DPH te tohu 1-5V ki tētahi kāri Tāuru Analog i runga i te PLC.
- Mahi: Ka whakarerekē te PLC i te takirere taurite, ka whakaoho rānei i te whakaoho mēnā ka rerekē te uara anaro.
Ngā Kāhua Tāutanga
- Momo A (Whakaurua): Tinana tapawhā paerewa me te whakaaturanga mamati.
- Momo B (Upoko Mamao): He pane pūoko iti (raupapa DPH-100) e hono ana ki tētahi pūmana matihiko motuhake (raupapa DPA), he mea tino pai mō ngā wāhi tino kuiti, ngā wāhi wiri nui rānei.
