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.
APPLICATIONS- 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
