  • Overview
  • Series Specifications
The PH Series pressure transducers are designed for steam, air, gas, and liquid pressure measurement in all media compatible with 17-4 PH stainless steel. They utilize a microprocessor controlled sensor profiled for exceptional accuracy and reliability. All models feature three switch-selectable ranges and a “test mode” to verify wiring and panel input scaling. A pushbutton and digital input terminal is used to automatically zero the output, and the microprocessor safeguards against accidental zero adjustment during operation. The field-selectable output, offering options of 0-5V, 0–10VDC, or 4-20mA, ensures excellent systems compatibility. Jumper controlled surge damping is provided on all models to prevent false alarms.

  • Chilled and hot water pump monitoring
  • HVAC and industrial gas monitoring
  • Instrument air pressure
  • Hydraulic oil pressure
Exceptional accuracy and stability
  • Micromachined silicon sensor design...improves overpressure capacity and prevents failures
  • Electronic surge damping for high stability
  • Pushbutton zero calibration...no trim pots to adjust, saves installation time
Lowest total installed cost
  • Switch-selectable pressure ranges...fewer models to order and stock
  • Pushbutton and remote zero adjustment...maintain accuracy and prevent callbacks with automatic zero calibration
Microprocessor controlled signal conditioning
  • Noise rejection reduces fluctuating readings due to noise or turbulence
  • Surge damping prevents false alarms by averaging fast peaks
  • Output clamping protects controller input from overcurrent/overvoltage
  • Test mode overrides the output to full scale...helps to diagnose wiring problems
  • Input Power 12 to 30VDC/24VAC
  • Output 3-wire transmitter; user selectable 4-20mA, (clipped and capped)/0-5V/0-10V*
  • Accuracy ±1% F.S. Combined linearity, hysteresis, and repeatability
  • Surge Damping Electronic; 5-second averaging
  • est Mode Overrides output to full-scale (20mA, 5V, 10V)
  • Pressure Ranges 62.5/125/250 psig switch selectable
  • Product Operating Environment -10° to 55°C (-4° to 130°F); 0 to 90%RH, non-condensing
  • Long Term Stability ±0.25% per year
  • Zero Adjust Pushbutton auto-zero and digital input (2-pos terminal block)
  • Status Indication Dual-color LED: Green = Normal, Red = Overpressure, Flashing Red = Fault
