The Graco 15T500 is engineered for precision measurement in demanding industrial environments. Compatible with high-pressure filtration systems and popular airless sprayer setups, it helps ensure consistent output for professional coatings applications. Featuring corrosion-resistant stainless steel housing and a clear, easy-to-read dial, the instrument is optimized for seamless integration into control panels on spray rigs and filtration units. Available in panel-mount format, it provides dependable accuracy over long service intervals.
Ideal for use in painting studios, manufacturing facilities, and maintenance workshops, this gauge minimizes downtime by providing stable readings under fluctuating pressures. The panel mount design simplifies installation into existing system dashboards, while the rugged construction resists vibration and corrosion. Technicians appreciate its compatibility with various fluids, monitoring capabilities, and long-term durability, making it a vital component for precision fluid control in any professional spray or filtration setup.
Graco’s 15T500 Gauge, Pressure, Panel Mt, 1.5-inch is a compact instrumentation solution engineered to deliver precise monitoring in industrial fluid delivery. Designed for integration into control panels of airless sprayer systems and closed-loop chemical feed, the gauge features a low-mass beryllium copper sensing element coupled to a glycerin-filled stainless steel housing, ensuring stable readings under pulsation and vibration. The clear polycarbonate lens and contrasting dial scale allow rapid setpoint confirmation, reducing operator error. Field technicians rely on this 1.5-inch diameter unit for accuracy across a broad thermal range, making it a cornerstone component for professional coatings and high-pressure fluid management.
Within demanding high-pressure filtration loops and automated spray manifolds, the Graco 15T500 withstands fluid temperatures up to 145°F and proof pressures to 1.5 times maximum scale. Its sealed window and gland-packed stem eliminate ingress and fluid loss, preserving durability in harsh environments. The gauge’s ANSI B40.1 compliant scale and dual graduations permit simultaneous reading in psi and bar. Technicians optimizing pump efficiency will appreciate the minimal dead volume connection and robust 1/4″ NPT process fitting, which reduce line restriction and maintain system performance under fluctuating load conditions. The polished internals facilitate cleaning and decontamination during routine maintenance.
The construction of the 15T500 centers on a welded stainless steel case married to a precision-formed brass bourdon element, providing excellent chemical compatibility with solvents, oils, and water-based coatings. Internally, all wetted parts utilize 316L stainless steel and phosphor bronze to balance response time with corrosion resistance. The back-mounted connection reduces stress on the sensor element during panel installation. Premium-grade glycerin fill dampens needle oscillation, which is crucial for protecting sensitive components in pulsating circuits. This material synergy supports long-term service life by minimizing wear and chemical attack in aggressive process streams.
Calibration is certified to ±2% full scale, ensuring repeatable measurements for closed-loop control in spray circulation systems. The gauge resolution of 1.5% of full-scale range delivers fine granularity vital for maintaining pressure setpoints in fast-acting valves and regulators. Dynamic response time is less than 2 seconds for step changes, aiding quick troubleshooting in airless sprayer assemblies. Cycle life exceeds 50,000 operations under rated conditions, supporting maintenance cycles aligned with standard production schedules. Use of this instrument can improve system stability and reduce overshoot in high-flow piping networks.
Ideal for monitoring supply pressure in paint supply modules, the 15T500 gauge integrates seamlessly with electro-hydraulic control panels and batch dispensing rigs. It is frequently specified in turnkey systems for resin transfer molding (RTM) and high-performance sealant injection processes. The instrument’s compact form factor allows multiple units to occupy minimal panel real estate, facilitating distributed sensing in temperature-controlled ovens and curing lines. Integration with data acquisition systems is straightforward via analog transmitter retrofits, enabling real-time logging for quality assurance in professional coatings operations.
Operators should employ proper torque on panel nuts to preserve the calibration of the bourdon tube without over-stressing the housing. Regular inspection of the fill fluid condition and lens alignment is recommended every six months in continuous-use scenarios. In applications with abrasive or particulate-laden fluids, prefiltration through 20-micron filters safeguards the sensor element and prolongs compatibility with line accessories. Calibration checks aligned with ISO 9001 protocols help maintain compliance in regulated production environments.
Incorporating this gauge into a fluid control assembly enhances system responsiveness and reduces downtime by providing clear visual feedback on pressure conditions. Its robust design improves seal longevity at connection points and withstands ramp-up cycles in batch processing. When combined with proper high-pressure filtration and maintenance of pump efficiency, the 15T500 contributes to smoother start-ups and consistent coating thickness in automated spray booths. This panel-mount solution exemplifies precision monitoring for demanding industrial applications, from chemical dosing skids to coating roll coaters.
