Bioprocess OEMs demand sensors that work outside single-use systems without contaminating the fluid path. SMD's non-invasive portfolio is purpose-built for pharma-grade environments.
Sensor Families
Thin film load cells for single-use bag weighing, bioreactor vessel weight monitoring, and inline dispensing gravimetric verification across upstream and downstream bioprocessing.
Process pressure monitoring for bioreactor headspace, media transfer lines, and filtration systems. Wetted designs available in pharmaceutical-grade materials.
Clamp-on pressure sensors for single-use tubing lines where disposable fluid paths must remain completely closed and uncontaminated.
Air bubble detection in chromatography columns, media transfer lines, and sterile filtration circuits. Clamp-on design preserves single-use integrity.
Non-contact flow measurement in single-use bioprocess tubing for media, buffer, and harvest fluid transfers — fully compatible with gamma-irradiated disposable tubing sets.
External non-contact level sensing on single-use bags, stainless bioreactors, and media prep vessels to replace invasive float sensors in cleanroom environments.
Applications
Weight-based monitoring of single-use bag bioreactors combined with headspace pressure sensing for complete vessel control without invasive penetrations.
Flow and bubble monitoring in media transfer lines and reagent dispensing systems ensuring accurate volumes and contamination-free fluid paths.
Pressure sensing across filter housings and tangential flow filtration systems with pharma-grade wetted materials and full CIP/SIP compatibility.
Bubble detection protecting packed chromatography columns from gas slugs, combined with pressure monitoring for column integrity verification.
External ultrasonic and capacitive level sensing on bioreactor vessels, harvest tanks, and media prep containers throughout the bioprocess train.
Full sensor packages for downstream purification skids, buffer prep systems, and fill-finish lines with pharma-grade documentation and traceability.
We supply pharma OEMs with complete sensor packages including GMP documentation, material certifications, and long-term supply agreements compatible with FDA and EMA requirements.
