Pressure | Wet | Panel | 0-250PSIG

Description

The PH Series pressure transducers are designed for steam, air, gas, and liquid pressure measurement in all media compatible with 17-4PH N8 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 guards 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 reduce false alarms.

Applications

• Chilled and hot water pump monitoring
• HVAC and industrial gas monitoring
• Instrument air pressure
• Hydraulic oil pressure

Features

• Micromachined silicon sensor design improves overpressure capacity and reduces failures
• Electronic surge damping for high stability
• Pushbutton zero calibration no trim pots to adjust, saves installation time
• 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 (see graph)
• Noise rejection reduces fluctuating readings due to noise or turbulence
• Surge damping reduces 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
