This physiological blood pressure transducer uses a semi-disposable dome of medical grade Silastic® with an integral silicone rubber diaphragm. Blood only contacts the diaphragm. Domes are supplied sterile and can be re-sterilized and reused without affecting calibration. Replacement domes are available as accessories.
This transducer converts picofarad changes of capacitance into high-level DC voltages using a new electronic circuit (U.S. Patent #4,142,144). This circuit is extremely sensitive and stable, producing a signal suitable for direct connection to recorders, oscillographs and computers.
The transducer amplifier has a 3-digit back lit LCD display that reads directly in mmHg up to 999. Amplifiers can be stacked for multiple use. It is possible on special order to have as many as 4 amplifiers operated by one transformer.
Please note that replacement domes listed on this page are for Harvard Apparatus’ newer model transducer ONLY. The newer model is distinguished by a black threaded ring at the base of the dome. The older models have a white ring at the base of the dome. We are no longer able to offer replacement domes for these older units.
