Kudzvinyirira: Simba remvura yepakati inoshanda pane unit unit.Yayo yemutemo unit yekuyera ndeye pascal, inomiririrwa naPa.
Absolute pressure (PA): Kudzvanya kuyerwa zvichibva pane absolute vacuum (zero pressure).
Gauge pressure (PG): Dzvinyiriro yakayerwa zvichibva pamhepo chaiyo.
Kumanikidzwa kwakasimbiswa (PS): Dzvinyiriro yakayerwa zvichibva pane yakajairwa mhepo kumanikidza (101,325Pa).
Negative pressure: Kana kukosha kwegauge pressure
Differential pressure (PD): Musiyano wekumanikidza pakati peapi mapoinzi maviri.
Pressure sensor: Chishandiso chinonzwa kudzvanywa uye chinoshandura chiratidzo chekumanikidza kuita chiratidzo chemagetsi chinobuda zvinoenderana neimwe pateni.Iko hakuna amplifier circuit mukati me sensor.Iyo yakazara chiyero inoburitsa kazhinji milivolt unit.Iyo sensor ine yakaderera kutakura simba uye haigone kusanganisa komputa zvakananga.
Pressure transmitter: Iyo transmitter inogona kushandura chiratidzo chekumanikidza kuita yakajairwa magetsi ekuburitsa siginecha ine inoenderera mutsara inoshanda hukama.Iwo akabatana mwero yekubuda masiginecha anowanzo akananga ikozvino: ① 4 ~ 20mA kana 1 ~ 5V;② 0~10mA 0~10V.Mamwe marudzi anogona kubatanidza nekombuta zvakananga.
Pressure transmitter = Pressure sensor + Dedicated amplifier circuit
Mukuita, vanhu kazhinji havaite mutsauko wakasimba pakati pemazita emidziyo miviri.Mumwe munhu anogona kutaura nezve sensor iyo howerver inoreva chaizvo kune transmitter ine 4 ~ 20mA inobuda.
