proliferate-silicon pressure Transmitter

1) summary
    LU-K adopts proliferate silicon isolating sensors groupware which produced by famous NovaSensor, American company and with high precision & high stability. Through high stability amplifier electric circuit and accurate temperature compensation, it can transfer the absolute pressure or gage pressure of measured medium to 4-20 mADC standard electric signal.
    Exquisite seal technology and perfect installation process can insure the high quality & best performance. Complete specification, standard connection and convenient Zero & Span adjustment, can widely suit for user's requirement.
   LU-K have three types:common type,intrinsically-safety type and isolating-explosion type.Intrisically-safety types:common type,intrinsically-safety type and isolating-explosion type. Intrinsically-safety type and isolating-explosion type can be used to each kind of execrable or hazardous industry field.

2) characteristic:
2.1 0-3Kpa to 0-60Mpa
2.2 direction process connection, not need assembly bracket
