Veris Industries PH SERIES Data Sheet
Pressure Monitoring | Digitally Controlled Gauge Pressure Transducer
PH SERIES
Three Switch-Selectable Ranges
with Test Mode
PH
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 switchselectable 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 to 5 V, 0 to 10 Vdc, or 4 to 20 mA, ensures excellent systems
compatibility. Jumper controlled surge damping is provided on all
models to reduce false alarms.
Reduces failures
