Pressure gauge dikna chu a dikna grade atanga a lan ber a ni.
Accuracy grade hi pressure gauge-a key parameter a ni a, a tehna result dik leh dik loh a tarlang a ni. A tlangpuiin, accuracy grade chu number hmanga entir a ni a, chu chu 1.0, 1.6, emaw 2.5 te hi a ni. He number hian pressure gauge-a tihsual phal ber chu a tehna range atanga percentage anga a entir a ni.
Entirnan, Class 1.0 pressure gauge pakhatin 0-10 MPa inkar a neih chuan a tihsual phal ber chu range (10 MPa) chu accuracy grade (1.0%) nena inmil percentage nena puntir a ni a, chu chu 0.1 MPa a ni. Chumi awmzia chu tehna range pumpuiah hian he pressure gauge-a tehna dik lo hi ±0.1 MPa aia tam a ni lo vang tihna a ni.
Pressure gauge dikna grade hi a design leh siam danah a innghat a ni. Thil tam takah a innghat ber a, chung zingah chuan gauge siam dan, elastic element mizia, transmission mechanism dik leh siam dan te pawh a tel. High-precision pressure gauge-ah hian elastic element dik zawk an hmang tlangpui a, chu chu special alloy hmanga siam Bourdon tube te hi a ni. Heng elements te hian elastic property stable leh precise zawk an pe a, transmission mechanism pawh precision sang zawka design leh siam a ni a, chu chuan measurement error a ti tlem a ni.
Accuracy level hi pressure gauge dial-ah tarlan a ni tlangpui a, nameplate-ah emaw, a kaihhnawih marking area-ah emaw a ni. Hei hian pressure reading rintlak leh rintlak loh chu accuracy level atanga teh theihna a siamsak a ni. Entirnan, scientific experiment leh high-precision industrial process control ang chi application-te chuan tehna data dik tak neih theih nan accuracy level sang zawk nei pressure gauge an mamawh a ni.
Chubakah, pressure gauge dikna chu a hnathawhna hmunin a nghawng thei bawk. Entirnan, temperature inthlak danglamna hian elastic element elastic modulus a tidanglam thei a, chu chuan tehna dikna a nghawng thei a ni.
