Millar PCU-2000 Dual Channel Pressure Control Unit With Patient Isolation

The Millar PCU-2000 is a dual-channel, line-powered bridge amplifier that conditions signals from Millar Mikro-Tip® catheters for connection to CE-approved pressure monitors and data acquisition systems. Designed for clinical and laboratory pressure measurement, it provides electrically isolated patient inputs protected against cardiac defibrillator discharge, along with isolated bridge excitation and universal analog output. The unit automatically adapts to global line voltages (100–240 V AC) and delivers <±1 mmHg or 1% of reading accuracy with low noise and wide bandwidth.

– Key Features

• Patient isolation with defibrillator protection on all inputs
• Electrically isolated bridge excitation
• LED bar graphs for transducer status confirmation
• Lighted push-button calibration controls
• Color-coded Redel® pressure input connectors
• Global voltage auto-adaptation

– Typical Applications

Invasive pressure monitoring in operating theaters, catheterization laboratories, and intensive care units. Compatible with hemodynamic monitoring systems and research-grade data acquisition platforms requiring galvanic isolation and precise waveform fidelity.

– Compatibility & Integration

Accepts one dual-sensor or two single-sensor Millar Mikro-Tip® catheters via Viking or low-profile connector interface cables (PEC-1.5C, PEC-10C, PEC-4D, PEC-10D available separately). Pressure output via 1/4-inch phone-jack connectors; requires separately purchased BNC to audio adapters (6.5 mm, 2 m) for instrument interface connection.
