Detail LU-K Proliferate Silicon Pressure Transmitter

LU-K proliferate silicon pressure transmitter.

1. summary:

LU-K adopts proliferate silicon isolating sensors groupware which produced by famous NovaSensor, American company and with high accuracy & 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 4~20mADC 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. Intrinsically-safety type and isolating-explosion type can be used to each kind of execrable or hazardous industry field.

2. characteristic:

·0~3Kpa to 0~60Mpa,

·direction process connection, not need assembly bracket,

·zero & span external continually adjusted,

·prevent lightning strike and radio disturbance,

·with field indicate meter,

·Intrinsically-safety or isolating-explosion,

·Compact, beautiful appearance and competitive performance & price,

·High accuracy, high stability and high reliability.

3. applicant:
