01 · Application

Precision in every industry.

From pharmaceutical cleanrooms to ATEX zones — the ring balance delivers reliable measurements where conventional sensors fail.

01 · Application

Pharma & GMP

Continuous monitoring of room pressures in pharmaceutical cleanrooms per GMP requirements. The ring balance delivers stable analog readings without drift errors.

A · Challenge

Electronic sensors drift in controlled cleanroom environments — recalibration intervals shorten, operating costs rise.

B · Solution

The ring balance does not drift — no readjustment, no maintenance downtime. Where calibration is mandated by regulation (GMP, ISO 14644), calibration history typically shows no deviations: intervals significantly extendable.

Typical applications
  • Pharma manufacturing GMP A-D
  • Blood bank & plasma
  • Lab rooms (BSL)
  • Medical device production
  • Sterile laboratories

02 · Application

Semiconductor & Microelectronics

Monitoring and control of cleanroom pressures in semiconductor manufacturing — ISO classes 1–5 with the highest demands on particle density and pressure stability.

A · Challenge

Modern chip fabs require stable positive and negative pressure zones. Sensor failure or drift means production downtime and yield loss.

B · Solution

The ring balance operates drift-free and maintenance-free — no readjustment, no failure from electromagnetic interference.

Typical applications
  • Wafer fabrication
  • Lithography cleanrooms
  • MOCVD & epitaxy
  • Flat panel display production
  • Optical industry

03 · Application

Ventilation & HVAC

Monitoring and control of filter systems and supply/exhaust air differentials in building and industrial technology.

A · Challenge

Filter monitoring in HVAC systems requires reliable long-term measurement — electronic sensors need regular maintenance.

B · Solution

The ring balance monitors filter fouling permanently without maintenance intervals. Optional contacts for filter alarms.

Typical applications
  • HVAC filter monitoring
  • AHU centrals
  • Tunnel ventilation
  • Industrial exhaust systems
  • Laboratory fume hoods

04 · Application

Furnace & Thermal Processing

Differential pressure measurement in high-temperature furnaces, combustion chambers, and process furnaces.

A · Challenge

In high-temperature environments, electronic sensors fail due to thermal expansion and EMI interference.

B · Solution

The fully mechanical measuring principle without electronics in the measuring element is immune to heat and electromagnetic fields.

Typical applications
  • Continuous furnaces
  • Combustion chambers
  • Calcination plants
  • Ceramic and glass kilns
  • Hardening facilities
Biogas & Energy

05 · Application

Biogas & Energy

Monitoring of gas pressures, gas tightness, and pressure control loops in biogas plants and gas distribution networks.

A · Challenge

Biogas plants require explosion protection and intrinsically safe instruments — many standard sensors are not approved for these environments.

B · Solution

ATEX-certified variant (RW65_EX_II) approved for Zone 1 and Zone 21 — fully intrinsically safe, without external barrier.

Typical applications
  • Biogas storage
  • Gas flares
  • Gas line monitoring
  • Biomass plants
  • Landfill gas
Hazardous Area (ATEX)

06 · Application

Hazardous Area (ATEX)

Certified versions for explosive atmospheres per ATEX 2014/34/EU — for both gas and dust.

A · Challenge

In Ex zones all measuring equipment must be certified and intrinsically safe — standard transmitters require external Zener barriers.

B · Solution

The RW65_EX_II is intrinsically safe per Category II 1G/D — direct mounting in Zone 0, 1, 2, 20, 21, and 22 without additional protection.

Typical applications
  • Chemical plants
  • Paint booths
  • Dust processing plants
  • Tank farms
  • Mills and silos
