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~*0mADC 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.
