FEATURES

Bright LED display of pressure and switch status All stainless steel wetted parts Internal “push-button” configurability allows quick user pressure range changes or relay adjustments External “push-button” allows user to display P1, P2 or DP without opening cover TYPICAL USES Tank level pressure measurement Pump controls Compressor control Filter monitoring HVAC Hydronic cooling/heating systems KEY BENEFITS

  • Robust aluminum die cast housing
  • Two sensor design well suited for high DP ranges
  • Min./Max. feature records, low/high pressure events
  • Two polysilicon thin film sensors to achieve wet- wet, high differential pressure measurements
  • Monitors/controls a wide variety of wet/dry media PERFORMANCE SPECIFICATIONS Reference Temperature: 75 °F (24 °C) Analog Output: 4-20 mA or 1-5 Vdc Accuracy: ±0.5% of span Includes linearity, hysteresis and repeatability Response Time: 20 ms Output Resolution: ±0.2% of span Stability: ±0.5%/year Pressure Switch Output: Number of Contacts: 2 Response Time: 20 ms-2.0 sec (by user) Type: TTL/CMOS up to 40 Vdc / 200 mA Setting Accuracy: ±1.0% of span Hysteresis: Variable deadband (by user) Display: Accuracy: ±1.0% of span Type: 3½ digits, 10 mm LED ENVIRONMENTAL SPECIFICATIONS Temperature Limits: Storage: Operating: Compensated: −4 °F to 140 °F (−20 °C to 60 °C) 14 °F to 122 °F (−10 °C to 50 °C) 14 °F to 122°F (−10 °C to 50 °C) Thermal Coefficients: (ref. 75°F (24°C)) Zero & Span: ±0.05% of span/°C FUNCTIONAL SPECIFICATIONS Static (Line) Pressure Pressure Range: 75 to ≤300 psi Proof:
