Sensors That Withstand Sterilisation, High-Heat, and Dust-Loaded Zones
In pharmaceutical machinery, regulated measurement accuracy is essential for safe and compliant operation. From differential pressure in laminar-flow hoods to critical airflow in isolators, moisture control in dryers, and process-gas monitoring in packaging machines, sensors must deliver stable readings under harsh conditions. E+E Elektronik sensors are engineered to support compliance with GMP guidelines and, where required, ATEX/IECEx standards. Hydrogen peroxide sterilisation, high temperatures, solvents, and dusty or explosive atmospheres quickly push standard sensors to their limits, leading to drift, frequent servicing, and complex multi-supplier validation.
Catalytic H₂O₂ filter caps, stainless-steel housings, and E+E’s proprietary sensor coating ensure long-term stability under aggressive cleaning
EN ISO/IEC 17025-accredited calibration with BEV/E+E designation provides NMI-level traceability and compliant documentation
Auto-zero differential pressure, modular probes, and digital interfaces support fast commissioning and stable operation
One partner offering a complete sensor suite with global support reduces supplier complexity and simplifies validation

Advantages of E+E Sensors in Pharmaceutical Machinery
In pharmaceutical machinery, sensors must endure frequent sterilisation, aggressive cleaning, and 24/7 operation. Extreme humidity levels, solvents, and thermal cycling often cause sensor drift and performance degradation over time. E+E sensors are developed and manufactured entirely in-house from the sensing element to the assembled transmitter. This vertical integration provides full control over all materials and process steps, delivering outstanding long-term stability and reliability in demanding pharmaceutical environments.
Sterilisation with hydrogen peroxide (H₂O₂), alcohol-based cleaning, solvent exposure, and temperature extremes place extreme stress on sensitive measurement components. E+E sensors are engineered to withstand these stresses through:
Protective sensor coatings and filters that shield humidity and temperature sensing elements from solvents and chemical residues.
ARC (Automatic ReCovery) that actively restores sensor performance after exposure to alcohols or cleaning vapours.
Catalytic H₂O₂ filters to prevent degradation during bio-decontamination cycles.
Ceramic-based sensing elements in air-velocity probes offering exceptional mechanical and chemical stability.
Stainless-steel housings and interchangeable filter caps providing durable protection against corrosion and contamination build-up.
This robustness ensures consistent performance when sterility and uptime are critical.
Machine builders in the pharmaceutical sector require multiple measurement parameters, yet prefer a single trusted partner. Managing several instrument suppliers increases validation effort and complicates documentation. E+E Elektronik provides a comprehensive sensor portfolio for humidity, temperature, differential pressure, air velocity, air flow and dew point. A unified platform design simplifies mechanical and electrical integration, reduces qualification time, and ensures consistent quality across all parameters.
Regulated industries demand verifiable accuracy and documented compliance. Calibration uncertainty or non-traceable certificates can lead to costly requalification or audit findings. E+E sensors are calibrated in the company’s EN ISO/IEC 17025-accredited, in-house laboratory, traceable to national metrology institute (NMI) standards. Each device ships with complete, traceable documentation, providing the certainty and transparency required for GMP, FDA-regulated environments, and ATEX/IECEx-classified zones.
Modern pharmaceutical machines rely on seamless data integration and minimal downtime. E+E sensors feature auto-zero calibration and a modular digital platform such as Sigma 05 with USB-C configuration and bus connectivity. These innovations ensure consistent process control, fast calibration checks, and straightforward integration into existing control architectures.
