DDM Sensors develops and manufactures pressure sensors for laboratory applications where compact installation space, signal stability, and reproducible measurement results must come together. Compact designs, suitable wetted materials, and seamless electrical integration are essential for this purpose. Our miniaturized pressure sensors are engineered specifically to meet these demands.
How Pressure Sensors for Laboratory Technology Work
Pressure sensors in laboratory applications capture operating pressure as gauge, absolute, or differential pressure and output the reading as a voltage or current signal. Depending on the configuration, DDM Sensors provides options including 0–5 V, 1–6 V, 0–10 V, 0.5–4.5 V, and 4–20 mA. For tight installation spaces, compact sensors featuring small process connections are ideal because they integrate directly into analytical and dosing channels.
For applications operating across broad temperature ranges, Total Error Band (TEB) serves as a critical performance parameter. Beyond basic accuracy, TEB accounts for non-linearity, hysteresis, zero-point and full-scale offset tolerances, as well as thermal effects describing the expected overall measurement deviation across the specified temperature range. Conversely, for applications under stable ambient conditions, such as room temperature, primary sensor accuracy takes precedence.
Selecting the Right Sensor for Laboratory Applications
Selecting a suitable laboratory pressure sensor depends primarily on measuring range, media compatibility, temperature limits, and mechanical integration. HPLC, microfluidic, and analytical systems frequently require low pressure ranges and compact process connections. When dealing with changing media or aggressive substances, wetted material selection and sensor durability become decisive.
The PV15 and PV22 series are particularly well suited for compact laboratory applications. The PV15 is available starting from 0–2 bar absolute and −1 to 1 bar gauge. For extremely low pressure ranges, the PV22 covers options from 0–250 mbar absolute and 0–100 mbar gauge. Depending on the model, both series feature temperature-compensated measurement across a wide operating range from −40 °C to +150 °C. All wetted components are constructed from seal-less, fully welded 1.4404 and 1.4435 (316L) stainless steel.
Relevant Measuring Methods and Technologies
Compact pressure transmitters with stable electrical output signals are essential for laboratory technology. Analog voltage signals integrate directly into evaluation electronics, control units, and test benches. The 0.5–4.5 V output of the PV-15H targets compact system architectures, while the PV-22 series provides versatile integration options with 0–5 V, 1–6 V, or 0–10 V outputs.
In laboratory settings with restricted installation envelopes, mechanical integration plays a crucial role. For the PV15 and PV22 series, various compact process connections are available, including M6x1, M8x1, M10x1, M14x1.5, 7/16-20 UNF, G1/4 male, and Rectus 21. Furthermore, DDM Sensors crafts custom pressure fittings to align sensors seamlessly with existing equipment, test benches, and custom fluid paths.
Application Areas
Chromatography, HPLC, and Gas Chromatography
Chromatographic systems demand stable pressure readings paired with a small footprint. Laboratory pressure sensors must integrate cleanly into pump modules, flow channels, and monitoring units without causing unnecessary flow restrictions. Miniaturized sensors featuring small process fittings and stable output signals are ideal for these environments.
Microfluidics and Lab-on-a-Chip Systems
Microfluidic devices impose strict requirements on envelope dimensions, pressure resolution, and system integration. Compact sensors with low measuring ranges and precise signal processing are vital here, as even minute pressure variations can impact system performance. DDM Sensors’ miniaturized pressure sensors support these applications through compact form factors and tailored electrical interfaces.
Dosing and Analytical Systems, Bioreactors, and Test Benches
Dosing units, analytical systems, bioreactors, fermenters, test rigs, and calibration devices depend on reproducible pressure measurements and long-term signal stability. Robust sensor integration is especially critical in laboratory environments characterized by changing media or frequent reconfigurations. The PV-15 and PV-22 series deliver the ideal combination of compact dimensions and practical pressure ranges for these setups.
DDM Sensors as Your Partner
DDM Sensors specializes in miniaturized pressure sensors and custom solutions for technical applications. For laboratory technology, this means sensors can be precisely aligned with required measuring ranges, mechanical interfaces, and electrical specifications. Laboratory equipment, test rigs, and analytical platforms can thus be equipped with tailored sensor solutions rather than compromising on space constraints or signal quality.
In addition to standard sensor configurations, we provide project-specific engineering when laboratory setups require unique connections, geometries, or signal protocols a key advantage when embedding sensors into proprietary device architectures or OEM applications.
