Introduction
L704 series digital pressure level transducer with high stable and reliable, which use USA GE pressure CHIPS and highaccurate circuit board into the stainless steel housing. Integrated construction and standard signal provide the user easy
and convenient application in the local working place. The special cable connects with housing, can be immersed into the
media for a long time. L704 series digital pressure level transducers are a high accuracy digital and intellectual product
development by MACSENSOR to meet the market needs of worldwide. L704 designed incorporating with monolithic
computer technology and sensor digital conversion technology, which core component adopts 24-bit AD MCU
micro-processor to ensure high quality of the transducer relaying on its strong function and high speed operation
capacity. The overall designed framework is to meet the requirements of increasingly enhanced industrial site application
with a view to reliability, stability, high accuracy and the product also features strong function and without manually operating
device to ensure good interaction. Application digital signal processing technology is made for good disturbance immunity.
It's also feature zero point automatic stable follow up capacity and temperature automatic compensation.
