Product Description
. . . . . 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 Â"test modeÂ" 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, 0Â-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. PRODUCT SPECIFICATIONS: 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).. Veris. Veris Industries. PHX08S.
