Strategic priorities

PreSens operates across 4 stated priorities, with the most concrete near-term plan anchored on sensor physics excellence.

Maintaining well-regarded optical sensing technology leadership through continued R&D in fluorescence quenching techniques for non-invasive oxygen, pH, and CO2 measurement.

Strengthening position as Tier 1 supplier to bioreactor manufacturers like Sartorius and Eppendorf through protocol modernization and plug-and-play integration capabilities.

Transforming PreSens Measurement Studio from passive data logger to active data hub with API connectivity and LIMS integration.

Challenges we see

  • Digital Integration

    Data Silo Architecture

    PreSens devices generate high-fidelity Process Analytical Technology (PAT) data but rely on manual CSV/Excel exports for data extraction, creating critical bottlenecks in Biopharma 4.0 workflows where real-time analytics and ALCOA+ compliance are mandatory.

    Customers requiring AI/ML optimization and real-time process control cannot use PreSens data effectively, driving them toward competitors with native cloud connectivity.

  • Operations Manufacturing

    Bluetooth Connectivity Instability

    The SFR vario system relies on consumer-grade Bluetooth Low Energy for data transmission inside incubators, causing frequent connection failures during critical 14-day mammalian cell culture monitoring where single batches can exceed $100,000 in value.

    Connection drops during high-value experiments create blind spots, and PreSens currently offloads reliability risks to users' IT environments rather than providing industrial-grade connectivity.

  • Digital Integration

    Legacy Industrial Protocols

    OEM Electro-Optical Modules (EOMs) communicate via RS232, RS485 (Modbus RTU), and USB - protocols dating to 1979 that lack metadata capabilities, security features, and bandwidth of modern OPC UA or MQTT standards.

    Integrators must build costly translation layers to ingest PreSens data into modern SCADA or cloud systems, potentially driving them toward competitors offering IoT-native sensors with built-in Ethernet connectivity.

  • Compliance Regulatory

    Compliance Validation Burden

    Pharmaceutical customers must independently validate their local PC configurations, backup procedures, and user access controls for 21 CFR Part 11 compliance, as PreSens does not offer compliance-as-a-service cloud infrastructure.

    Uncontrolled firmware updates via mobile apps create change control violations in GMP environments, and without managed fleet capabilities there are no centralized, documented rollouts required for validated processes.

  • Operations Operations

    Sensor Spot Calibration Logistics

    Each sensor spot batch has unique Stern-Volmer calibration constants that must be manually scanned or entered into software, creating friction in the cyber-physical system where high-precision digital sensors depend on manual information transfer.

    Mixing up batches or incorrect barcode entry causes erroneous measurements, and without cloud-based smart calibration lookup this drives operational risks and support burden.

Opportunities, by urgency and business impact

Each bubble is one opportunity, numbered to match the list below. Further right means it bites sooner; higher means a bigger effect on the business. A bigger bubble means a bigger implementation effort.

Source: A4BEE analysis of public sources

  1. Data Integration Gap

    PreSens Measurement Studio 2 lacks REST API or GraphQL interfaces, effectively air-gapping sensor data from laboratory digital ecosystems (LIMS, ELN, ERP) and preventing real-time AI/ML optimization of cell cultures.

    Develop middleware plugins and API wrappers that transform PreSens from a passive data logger into an active node in the Unified Namespace of modern labs, increasing hardware stickiness and preventing customer churn to competitors with better LIMS integration.

  2. Wireless Reliability Crisis

    SFR vario Bluetooth connections fail during experiments due to Windows power management overriding USB dongles and driver conflicts, causing data recording interruptions that can compromise entire batches worth over $100,000.

    Implement industrial-grade wireless stack with custom hardened BLE driver, local data buffering, and automatic reconciliation - directly reducing support tickets and protecting brand reputation for reliability.

  3. OEM Protocol Obsolescence

    EOMs rely on Modbus RTU/RS232 which forces integrators to build translation layers for modern SCADA/cloud systems, increasing integration complexity and threatening PreSens's position as preferred OEM choice for next-generation bioreactors.

    Design IoT Gateway module that translates Modbus to OPC UA/MQTT Sparkplug B at the edge, performs sensor health analytics locally, and enables remote diagnostics - future-readying OEM business without redesigning core sensor boards.

  4. Regulatory Compliance Overhead

    PreSens places entire 21 CFR Part 11 validation burden on pharmaceutical customers who must spend thousands validating local PC configurations, while mobile app firmware updates create uncontrolled change violations in GMP environments.

    Implement Managed Fleet Update system with enterprise portal for controlled firmware rollouts, automated audit trail generation, and compliance-as-a-service architecture that dramatically reduces customer validation costs.

  5. Calibration Data Management

    Sensor spot calibration constants require manual entry or barcode scanning, creating a break in the digital thread between manufacturing and measurement that risks erroneous results when batches are mixed or codes mistyped.

    Deploy cloud-based Smart Calibration system where QR scanning triggers automatic download of precise batch data and expiration dates, with usage tracking that alerts users when spots need replacement - enhancing UX and driving consumable sales velocity.
