Description

Pressure Measurement Instruments
SAF and EAF require monitoring of key pressure parameters including furnace chamber pressure, gas pressure, cooling water pressure, and hydraulic system pressure to ensure stable furnace pressure, equipment safety, and proper process operation.

2.1 Pressure Transmitter

TypeMeasuring PrincipleMeasuring RangeAccuracyOutput SignalApplications
Capacitive Pressure TransmitterCapacitance change-0.1~40MPa0.075%~0.1%FS4~20mA+HARTGeneral pressure, differential pressure
Piezoresistive Pressure TransmitterPiezoresistive effect-0.1~60MPa0.1%~0.25%FS4~20mAHydraulic system, oil pressure monitoring
Diaphragm-Sealed Pressure TransmitterIsolated diaphragm-0.1~10MPa0.1%~0.2%FS4~20mAClogging-prone, high-viscosity media
Low Differential Pressure TransmitterCapacitive/Silicon resonant0~1kPa0.1%FS4~20mAFurnace micro-differential pressure control (±15Pa)

2.2 Pressure Switch

TypeSetting RangeContact RatingProtection ClassFeaturesApplications
Mechanical Pressure Switch-0.1~40MPa10A/250VACIP65Simple structure, low costPressure high/low alarm, interlock protection
Electronic Pressure Switch-0.1~60MPa0.5A/24VDCIP67High accuracy, adjustable setpointAutomation control system pressure monitoring

2.3 Pressure Instrument Selection Reference
