Category: pressure gauge

产品描述标题.jpg

JFAK721 series smart pressure controller is a smart digital display pressure measurement 

and control product integrating pressure measurement, display, output and control. 

The front end adopts high accuracy pressure sensor, output signals are amplified and processed

by high-precision, low-temperature drift amplifiers feeding into high-precision A/D converters 

that are converted into digital signals that can be processed by the microprocessor.after the operation 

of the signal, the two-way switch is controlled to measure and control the pressure of the control system.
