JFAK721 4-20mA digital relay Pressure Transmitter Controller
widely used in hydro-power, tap water, petroleum,
chemical,mechanical, hydraulic and other industries,
to measure and control the pressure of fluid medium.
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.
◆ 4 bit digital display current pressure value
◆ Pressure preset switch point and hysteresis switch output
◆ Switch values can be set freely between zero point and full scale
◆ The shell is equipped with a nodal action light emitting diode, which is easy to observe.
◆ Buttons adjustment and set the various of parameters on site, easy to operate
◆ Strengthened anti-interference design, suitable for various electromagnetic harsh industrial environment
