SLU-L proliferate silicon liquid-level transmitter

.       Summary:

LU-L adopts proliferate silicon pressure 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 measured liquid signal to 4~20mADC standard electric signal.

Exquisite seal technology and perfect installation process can insure the high quality & best performance. LU-L have two structure types: one-body type and separated-body type, and according to measured mediums, there are electric cable type, armored type and anti-corrosive type. Armored type and anti-corrosive type can resist corrasion of several kinds of corrosive liquid, can widely suit for user’s requirement.

LU-L have two types: common type and intrinsically-safety & explosion-proof type. Explosion-proof type can be used to each kind of execrable or hazardous industrial field.
