The MKS PR4000B is a half-rack Digital Power Supply and Display module. It is available with either one or two channels, and has a 4.5 place backlit LCD display as standard. Both versions support internal or external set points and master/slave control schemes. The single-channel version can control one Baratron® pressure transducer or one Mass-Flo® meter or controller. The dual-channel version supports up to two pressure transducers or two mass flow controllers, or one of each.

Engineering units are user-selectable as Torr, mTorr, kTorr, Pa, kPa, cmH2O, psi, N/qm, ìbar, mbar and bar for pressure transducers; sccm, scm, slm, scfm, scfh for flow meters or controllers and V, % and °C.

Other Features:

Digital RS232 interface standard; RS485 interface optional on two-channel models

User-selectable engineering units for both pressure transducers and flow devices

Menu-driven with simple set-up and operation

Power Supplies/Readouts are designed to control and display any flow transducer. The flow rate set point can be adjusted either through front panel controls or remotely through the rear panel analog interface. The PR4000B Vacuum System Controller is a two channel/sequentially selectable single readout. Compatible with mass flow controllers and mass flow readouts. Signal cables and optional cards for the MKS PR4000B are available on this website.
