Core Hardware and Technical Characteristics
Sensing Core
Ion-implanted silicon piezoresistive sensor, integrated independent temperature and static pressure detection units, automatically corrects temperature drift and static pressure drift, full-scale high-precision stable measurement.
Remote Sealing Structure
Capillary + isolation diaphragm structure, suitable for high-temperature, high-corrosion, high-viscosity, and easily crystallizing media. The medium does not directly contact the transmitter body, preventing blockage and sensor corrosion.
Signal Output and Communication
Standard 4–20mA two-wire analog output
Compatible with DE digital communication protocol, supports SFC handheld operator, Experion PKS DCS two-way calibration, remote diagnosis
Diagnostic Function
Three-level self-diagnosis: diaphragm damage, capillary leakage, over-temperature, over-pressure, circuit break alarm, early warning of faults to avoid machine shutdown.
Explosion-proof Protection
Intrinsically safe explosion-proof, flameproof certification, can be used in chemical, oil and gas Class I Div2 hazardous areas; protection IP67. Power supply
Standard 24VDC two-wire circuit power supply, with low power consumption of the entire machine.
System Integration
DCS: Honeywell Experion PKS, ABB 800xA, GE Mark VIe, Triconex SIS systems
Field tools: SFC intelligent field configurator, offline/on-line range, unit, damping, alarm point modification
Companion instruments: Bently 3500 TSI, unit SIS safety interlock for pressure / level switch signal collection
V. Typical Application Scenarios
Petrochemical reaction vessels, towers, high-temperature / corrosive medium liquid level, pressure measurement
Power plant boiler drum, high and low pressure feed water, lubricating oil line pressure monitoring
Oil and gas long-distance pipelines, remote transmission liquid level / pressure monitoring
Air separation, metallurgy high-temperature viscous medium (asphalt, resin, slurry) pressure collection without blockage
Spare Parts Replacement and Fault Points
Replacement Requirements
It is mandatory to have a complete match for the entire string model STR94G-11A-1H0FGAEA7060-SB; any inconsistency in the segment code (diaphragm, filling liquid, range, capillary length, explosion-proof grade) cannot be directly substituted, and measurement drift, corrosion leakage, and explosion failure will occur.
Common Fault Phenomena
Value drift, zero point offset: leakage of capillary filling liquid, corrosion damage of diaphragm
No 4–20mA output, communication interruption: abnormal 24V power supply of the circuit, damaged circuit board
Fixed full range / zero position stuck: diaphragm blockage, capillary bending and blockage
Frequent fault alarms: environmental over-temperature, static pressure beyond the calibration range
Calibration Steps
Using SFC hand controller: zero point / range calibration → set damping time → enable fault diagnosis and alarm → simulate pressure calibration for linearity.
