FEATURES
Highly configurable: wide selection of pressure ranges, pressure connections and electrical terminations Available with externally adjustable zero and span access TYPICAL USES Oil field equipment Upstream oil and gas production Natural gas compression and transfer control Alternative energy projects KEY BENEFITS
- Provides the user with accurate, reliable, and stable output data
- Board microprocessor provides extremely linear and precise performance over the entire pressure and temperature range
- Ideal for a broad spectrum of pressure sensing requirements where Intrinsically safe or Non-Incendive hazardous location rating are required PERFORMANCE SPECIFICATIONS Reference Temperature: 70 °F (21 °C) Accuracy Class (Includes non-linearity): Terminal Point Method includes: hysteresis, non-repeatability, zero offset and span setting errors Best Fit Straight Line (BFSL): Add ± 0.05% for ranges >5,000 psi Durability: >10 million cycles Stability: ≤±0.25% span/year at reference conditions ENVIRONMENTAL SPECIFICATIONS Temperature Effects: -4 °F to 185 °F (-20 °C to 85 °C) ±1.0% of span for ±0.25% accuracy class ±2.0% of span for ±0.5% and ±1.0% accuracy class Temperature Limits: Storage: Operating: Compensated: -40 °F to 257 °F (-40 °C to 125 °C) -40 °F to 257 °F (-40 °C to 125 °C) -4 °F to 185 °F (-20 °C to 85 °C) Humidity Effects: 0-95% R.H. non-condensing (no effects) 0-100% R.H. with welded enclosure (no effects) FUNCTIONAL SPECIFICATIONS Response Time: < 2 ms Pressure Ranges: Vacuum, gauge, compound and absolute pressure from 0 to 5 psi through 0 to 10,000 psi (Bar ranges available) Shock: 100 g Peak, 11 ms Random Vibration: 10 g RMS, 20-2,000 Hz Sweep Vibration: 50-2,000 Hz, 5 g Peak Position Effect: ±0.02%, typical Overpressure: ≤300 psi ≥500 to ≤10,000 psi Proof: 1.5X Range 1.2X Range Burst: 2X Range 1.5X Range ELECTRICAL SPECIFICATIONS Circuit Protection: Reverse polarity and mis-wire protected Insulation Resistance (Circuit Case):
