Pressure Sensors

Pressure sensors are essential components in bioprocessing and cell culture systems, designed to provide accurate, real-time measurement of pressure within closed fluid loops. These sensors are critical for ensuring process stability, equipment safety, and fluid control in systems such as bioreactors, fermenters, filtration units, chromatography columns, and single-use assemblies. By enabling continuous monitoring of pressure conditions, they help optimize media flow, gas delivery, and filtration efficiency while preventing disruptions caused by overpressure, leaks, or flow restrictions. Used in both upstream and downstream applications, pressure sensors support workflows involving cell culture, microbial fermentation, buffer preparation, tangential flow filtration (TFF), and formulation and fill-finish operations. They are especially valuable in closed, sterile processes, where manual pressure checks are impractical or pose contamination risks. Integration of pressure sensors into automated control systems enables dynamic adjustments to pumps, valves, and flow rates—helping maintain critical parameters within defined specifications for GMP and FDA-compliant production. Available in both reusable and single-use formats, modern pressure sensors come pre-calibrated and sterile, ready for integration into single-use bioprocessing assemblies or hard-piped stainless steel systems. Sensor types include gauge, absolute, and differential pressure sensors, with outputs compatible with PLC, SCADA, or PAT systems. Materials used are typically biocompatible and USP Class VI-compliant, such as polycarbonate, stainless steel, or elastomeric diaphragms, ensuring compatibility with common sterilization methods like gamma irradiation and autoclaving. At Wasteless Bio, we supply surplus and refurbished pressure sensors from trusted manufacturers, suitable for a variety of process needs. Each listing includes specifications such as pressure range, sensor type, response time, output signal, material compatibility, and regulatory certifications. By sourcing pressure sensors through Wasteless Bio, laboratories and manufacturing teams can access high-precision monitoring tools while supporting cost-effective, sustainable biomanufacturing through equipment reuse and waste reduction.
