Foxboro P0916BT Bench Test Pneumatic Valve Positioner

Technical Specifications:

• Input Signal: 4-20 mA DC (simulated or actual)
• Output Signal: 3-15 psi (0.2-1.0 bar)
• Supply Pressure: 20 psi (1.4 bar) nominal, range 14-40 psi (1.0-2.8 bar)
• Actuator Type: Double-acting (simulated load)
• Ambient Temperature: -40°F to 185°F (-40°C to 85°C)
• Housing Material: Aluminum die-cast
• Enclosure Rating: IP54 (bench configuration)
• Response Time: ≤ 1 second
• Accuracy: ±1% of span
• Calibration Equipment Compatible: Standard bench test sets (Hart, Fisher, etc.)

Functional Features:

• Optimized for bench testing with accessible calibration points
• Simulated valve load port for bench verification
• Quick-connect pneumatic fittings for rapid setup
• Test point access for zero, span, and linearity verification
• No field-rated enclosure — intended for indoor shop use only

Performance Parameters:

• Deadband: Less than 0.5% of travel
• Hysteresis: Less than 0.5% of span
• Linearity: ±1% of span
• Repeatability: ±0.5% of span

Structural Features:

• Simplified housing without weatherproof sealing (IP54 rated)
• Bench mounting bracket or stand-alone configuration
• Exposed calibration screws for easy adjustment
• Quick-disconnect air fittings (1/4″ NPT)
• Multi-point test connections on terminal block

Working Principle:
The P0916BT operates on the same force-balance principle as field-mounted units. During bench testing, a simulated valve load (spring or pneumatic cylinder) is connected to the output port to replicate actual actuator forces. The test technician applies known input signals (4, 8, 12, 16, 20 mA) and verifies the output pressure response. Zero and span are adjusted using front-panel controls until the positioner meets specification.

Advantages:

• Rapid calibration and performance verification
• Reduces field commissioning time
• Cost-effective maintenance and overhaul verification
• Consistent testing environment ensures repeatable results
• Compatible with all P0916 field models for cross-verification

Applicable Industries:

• All industries using P0916 positioners (maintenance shops)
• OEM valve assembly facilities
• Third-party calibration laboratories
• Plant instrument maintenance departments

Installation Requirements:

• Indoor use only — not rated for outdoor or hazardous area installation
• Connect to clean, dry air supply at 20 psi (1.4 bar)
• Connect simulated load to output port per test procedure
• Use calibrated mA source and psi gauge for verification

Usage Notes:

• Do not install in the field — this is a bench-only configuration
• Perform full calibration cycle (zero, span, linearity, hysteresis) before release
• Document all test results per quality procedures
• Return to storage in clean, dry environment after use
