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 “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
FEATURES
● 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
●
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 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
