470 Series | Process Pressure Gauge
Razer Precision Instruments (RPI)
The RPI 470 Series is a heavy-duty process pressure gauge engineered for demanding industrial environments where durability, safety, and long-term accuracy are critical. Built with a phenolic case and stainless steel wetted components, it is designed to perform in corrosive, high-vibration, and high-pressure systems.
The SS316L Bourdon tube and stainless steel movement provide reliable measurement across pressure ranges up to 30,000 PSI, while the IP66-rated enclosure protects against dust and water ingress. A laminated safety glass lens enhances operator protection in hazardous conditions.
Designed for process applications, the 470 Series delivers stable, accurate readings in harsh environments where standard gauges are not suitable.
Typical Applications:
Oil & gas, chemical processing, refineries, high-pressure systems, corrosive environments, and process plants

PERFORMANCE ADVANTAGES
Why the RPI 470 Series Gauge Performs Where It Counts
DURABILITY IN HARSH ENVIRONMENTS
Phenolic case construction provides superior resistance to chemicals, UV exposure, and impact compared to metal housings. Combined with IP66 sealing, this ensures long-term operation in outdoor, washdown, and corrosive environments without degradation.
HIGH-PRESSURE & HIGH-STRESS RELIABILITY
The SS316L Bourdon tube and stainless internal components are designed to withstand high-pressure cycles up to 30,000 PSI. This reduces fatigue failure and ensures consistent measurement performance in demanding applications.
ENHANCED SAFETY & OPERATOR PROTECTION
Laminated safety glass lens and robust case design protect against gauge failure and pressure surges. Improves safety in hazardous environments where instrument integrity is critical.
ACCURACY UNDER VIBRATION & PULSATION
Liquid-filled options dampen vibration and pressure spikes, maintaining steady readings and extending gauge life in dynamic systems.
