Venous Pressure Transducers (P75)
Hugo Sachs' rugged low pressure transducer is highly sensitive for research and surgical applications involving liquids or gases.
- For low pressure applications with liquids and gases ±75 mmHg
- Excellent sensitivity and baseline stability
- Applications include:
- Venous blood pressure
- Esophageal pressure with fluid filled catheter
- Perfusion pressure in isolated lung and liver
- Perfusion pressure on perfused hollow organs, such as the esophagus - Robust construction with a removable Macrolon® dome, easy to fill, bubble free
- Transducer is a metal housing with ceramic pressure sensor giving the P75 excellent resistance to a variety of media

The P75 has a removable Macrolon® dome with a pressure connection and a vent connection at the side, so that it can be filled free of air bubbles. The dome connections have a male Luer taper so that suitable stopcocks can be attached. The transducer has a metal housing. The actual pressure sensor inside is made from ceramic and therefore has excellent resistance to different media.
The transducer's rugged construction can withstand pressure overloads up to 4000 mmHg without damage. It works together with any DC bridge amplifier (e.g., PLUGSYS TAM–A).
