Trycktransmittrar och tryckgivare anv\u00e4nds b\u00e5da f\u00f6r att m\u00e4ta och omvandla tryck till en elektrisk signal, men de har tydliga skillnader i funktionalitet, utsignal och till\u00e4mpning. <\/p>\n\n\n\n

1. Definition och funktion<\/strong>

<\/h2>\n\n\n\n
Funktion<\/strong> <\/td>Tryckomvandlare<\/strong> <\/td>Trycktransmitter<\/strong> <\/td><\/tr>
Definition<\/strong> <\/td>En enhet som omvandlar ett applicerat tryck till en elektrisk signal (vanligtvis mV, mA eller V). <\/td>En tryckgivare med inbyggd signalbehandling f\u00f6r att mata ut en standardiserad signal (t.ex. 4-20 mA eller digital kommunikation). <\/td><\/tr>
Arbetsprincip<\/strong> <\/td>Anv\u00e4nder ett avk\u00e4nningselement (tr\u00e5dt\u00f6jningsgivare, kapacitivt eller piezoelektriskt) f\u00f6r att omvandla tryck till en elektrisk signal. <\/td>Liknar en givare men inneh\u00e5ller ytterligare signalbehandling, temperaturkompensation och robust utg\u00e5ngs\u00f6verf\u00f6ring. <\/td><\/tr>
Utg\u00e5ngssignal<\/strong> <\/td>L\u00e5gniv\u00e5signaler: millivolt (mV), volt (V) eller motst\u00e5nd. <\/td>Signaler p\u00e5 h\u00f6g niv\u00e5: 4-20 mA, 0-10V, MODBUS, HART, etc. <\/td><\/tr>
Signalkonditionering<\/strong> <\/td>Kr\u00e4ver en extern f\u00f6rst\u00e4rkare f\u00f6r att f\u00f6rst\u00e4rka och bearbeta signalen. <\/td>Har inbyggd f\u00f6rst\u00e4rkning och kompensation f\u00f6r brus, temperaturdrift och signalstabilitet. <\/td><\/tr>
