Reliable Pressure and Gas Control for Industrial Environments
Industrial process systems depend on precise, durable, and safe instrumentation to maintain pressure and gas stability across production lines. Leierda delivers complete pressure measurement and gas control solutions — from high-pressure regulation to real-time monitoring — engineered for consistent accuracy, reliability, and safety in demanding industrial environments.
Core Challenges in Industrial Gas & Process Instrumentation
Industrial gas and process systems face high pressure, variable loads, and harsh conditions.
Leierda combines precise regulation, durable design, and reliable monitoring to ensure long-term stability and safety in continuous operation.
High Pressure and Dynamic Load Conditions
Process pipelines and gas networks can reach 20 MPa with fluctuating demand. Leierda single- and dual-stage regulators ensure precise outlet control and stable response, while transmitters provide continuous pressure monitoring for process safety.
Corrosion, Moisture, and Contamination
Industrial gases like oxygen, CO₂, hydrogen, and acetylene cause oxidation and corrosion. Leierda uses 316L stainless steel with PTFE seals and degreased, polished flow paths for lasting corrosion resistance and gas purity.
System Monitoring and Integration
Reliable automation requires accurate measurement and digital connectivity. Leierda gauges and transmitters offer local display and 4–20 mA / RS-485 outputs for seamless PLC, DCS, or SCADA integration.
Safety and Maintenance Reliability
Flammable, high-pressure systems demand strict safety control. Leierda integrates relief, filtration, and check mechanisms to prevent overpressure, backflow, and leakage — ensuring safe, low-maintenance operation.

Real-World Industrial Gas & Process Applications
Leierda pressure and gas control instruments are applied in various industrial sectors, providing reliable measurement, regulation, and system protection under demanding operating conditions.
Pressure Monitoring in Compressor Stations
Challenge: Continuous vibration and temperature fluctuation in an industrial compressor station caused gauge pointer oscillation and reading drift, reducing reliability and increasing maintenance.
Solution: Leierda supplied glycerin-filled stainless-steel pressure gauges with reinforced casings and damped movement mechanisms, hermetically sealed for humid, pulsating gas environments.
Result: Stable readings were maintained under severe vibration; inspection intervals doubled, maintenance workload dropped 30 %, and overall safety improved.
Pressure Signal Feedback in Automated Production Lines
Challenge: An automated packaging system required continuous pneumatic feedback for its PLC loop. Analog gauges provided no alarms or real-time data, causing undetected pressure drops and downtime.
Solution: Leierda installed compact pressure transmitters providing 4–20 mA / RS-485 output to the PLC, paired with local gauges for redundancy.
Result: Monitoring accuracy reached ±0.1 % FS, downtime decreased 25 %, and process stability significantly improved.
CO₂ Regulation in Beverage Processing Systems
Challenge: A beverage line experienced inconsistent carbonation and product foaming due to unstable single-stage CO₂ regulation.
Solution: Leierda implemented dual-stage stainless-steel CO₂ regulators with PTFE seals and precision gauges. Each unit was helium-tested ≤ 1 × 10⁻⁷ mbar·L/s to ensure gas purity.
Result: Outlet fluctuation was controlled within ±0.03 bar, eliminating foam loss and improving carbonation consistency across production.
Hydrogen Distribution and Regulation in Test Benches
Challenge: A hydrogen test bench required uniform multi-line regulation for cylinders up to 20 MPa. The existing manifold caused uneven pressure and delayed response.
Solution: Leierda designed a modular hydrogen manifold with dual-stage regulators, precision transmitters, check valves, and relief paths for independent line control.
Result: Pressure uniformity improved to ±0.02 bar with zero leakage after six months of operation, extending maintenance cycles and ensuring consistent test reliability.
