Applications

Pressure measurement in pipes and vessels for process control
Level measurement in pressurized tanks
Pump and compressor monitoring
General industrial pressure monitoring in chemical, oil & gas, and power plants
HVAC and building automation systems

Important Notes

The specific pressure range and process connection are defined by the model suffix
Requires a minimum loop resistance (typically 250Ω) for HART communication
The gauge pressure reference is atmospheric pressure
Sensor must be compatible with the process media (corrosion, temperature)
Proper mounting and impulse piping are critical for accurate measurement
