Pressure Sensor/Transmitter/Transducer

Vazhinji vanogona kuvhiringika pamusoro pekusiyana pakati, pressure sensor, pressurer transducer uye pressure transmitter mune akasiyana dhigirii. Aya mazwi matatu anogona kuchinjika mune mamwe mamiriro. Pressure sensors uye ma transducers anogona kusiyaniswa kuburikidza neinobuda chiratidzo. Iyo yekutanga inogona kutsanangurwa iine 4-20mA yekubuda chiratidzo nepo iyo yakazotevera iine millivolt chiratidzo. Mune mamwe mazwi, izwi rakakodzera rinogona kutariswa zvinoenderana nekubuda kwechiratidzo uye mashandisiro.

Pressure Sensor

Pressure sensor ishoko rakajairwa kune ese marudzi ekumanikidza, mudziyo unoshandiswa kuyera kudzvanywa. Mumazuva ese, iyo millivolt inobuda chiratidzo inochengeta yakasimba chiratidzo pasina kurasikirwa kana mudziyo wakadaro wakaiswa 10-20 tsoka kure nemagetsi. Iyo 5VDC inopa ine 10mV/V inobuda chiratidzo inoburitsa 0-50mV inobuda chiratidzo. Tekinoroji yekare inongoburitsa 2-3mV/V (millivolts per volt) nepo nyika-ye-the-art inokwanisa kugadzira 20mV/V zvakavimbika. Millivolt inobuda inosaina nzvimbo dzemainjiniya kuti adzore chiratidzo chekubuda zvinoenderana nezvinodiwa zvehurongwa uye kuderedza saizi yepasuru pamwe nemutengo.

Pressure Transducer

Pressure transducer kubuda yakakwira level voltage kana frequency siginecha inosanganisira 0.5 4.5 V ratiometric, 1 - 5 V uye 1 - 6 kHz. Output singal inoenderana nekupa mune zvese. Voltage inobuda masiginecha inokwanisa kupa yakaderera ikozvino kushandiswa kune iri kure batter inoshanda michina. Supply voltages kubva pa8-28 VDC inoda 5VDC inodzorwa, kunze kweiyo 0.5 - 4.5V inobuda. Dambudziko rinonyengera remagetsi emagetsi ekubuda masaini haapo "live zero", pane chiratidzo kana sensor iri pa zero kudzvanywa. Iyo yekare sisitimu inowanzotadza kuona mutsauko pakati peyakakundikana sensor isina kubuda uye zero kudzvanywa.

Pressure Transmitter

Pressure transmitter inoshanda kuburikidza nechiyero chazvino chechishandiso pane voltage. Hunhu hunonyanya kujeka ndeye ikozvino kubuda chiratidzo 4-20mA. Lonnmetermapressure transmitterszvakagadzirirwa kutarisa kumanikidzwa kwengarava, mapaipi kana matangi munguva chaiyo. 4-20mA pressure transmitters inopa yakanaka yemagetsi ruzha immunity (EMI/RFI), uye inozoda magetsi e8-28VDC. Nekuti iyo siginecha iri kugadzira ikozvino, inogona kupedza hupenyu hwebhatiri hwakawanda kana ichishanda nekumanikidza kwakazara.
