BioPAT® Pressure

The BioPAT^® Pressure sensor measures the pressure in liquid-flow tubes and converts it into an electrical signal. The BioPAT^® Pressure sensor consists of a multi-use pressure transmitter and a single-use pressure pipe.

The data can be read out by connecting the transmitter to a process control unit or to a desktop display. The sensors of the BioPAT ^® single-use Pressure family are highly chemically resistant and compatible with a broad spectrum of liquids with respect to viscosity, opaqueness, corrosiveness and temperature.

The BioPAT^® Pressure sensor uses the piezoresistive effect to accurately and quickly determine the pressure. Once the pressure pipe is assemble onto the transmitter, the silicone membrane on the single-use pressure pipe contacts with the metal membrane on the transmitter. While measuring, pressure variations result in a force applied to membranes that is detected by a piezoresistive pressure sensor inside the transmitter. In addition, an integrated thermometer automatically corrects the influence of temperature in the outlet signal.

The BioPAT^® Pressure sensors can be purchased as configured sensor transfer-sets for functional filtration units. The sensors are part of a comprehensive single-use and advanced analytics portfolio that provides robust and reliable measurements of critical process parameters and enables highly automated single-use bioprocessing within your design space.
