Functions

1. Remote real-time pressure monitoring: remove manual round-inspection of local-site pressure-gauges.

Operators monitor key-point pressures (desander feed-port overflow-port underflow-port) directly inside central-control-room without site-by-site field readings.

Greatly operational-efficiency especially for large-scale continuous corn-starch-production-lines. Stabilize process-parameters & preserve desanding-efficiency: Pressure constitutes a decisive operating-variable governing hydrocyclone desanding-performance.

Transmitter output signal can interlock with pump-variable-frequency drive control-systems. Upon feed-pressure deviation.

Pump rotational-speed auto-adjusts locking operating-pressure within optimal working-window 25–0.40MPa. Mitigates desanding-efficiency degradation and accelerated spare-part wear originating from pressure-swing events.

Abnormal-condition early-warning & fault-diagnostics: Configurable high-/low-pressure alarm thresholds. High-pressure alarms give advance notification of pipeline blockage or hydrocyclone grit-packing faults.

Low-pressure alarms flag insufficient feed-supply, pump-malfunction or piping-leakage events. Assists maintenance-staff with rapid-fault-localization and reduces production-downtime.

Production-data traceability & process-optimization support: Long-term archival recording of operating-pressure datasets supports analysis of desanding-equipment operating-state and spare-part wear-trend evolution.

Supplying quantitative reference data for process-parameter tuning and preventive-replacement-cycle definition.

Principle & Corn-starch desanding-section deploys exclusively diaphragm-isolated pressure transmitters. Unit is split into five functional assemblies: process-connection fitting.

Diaphragm measuring-chamber sensor-sensing-core signal-conditioning-electronics and electrical-junction-box.

In operation: starch-slurry process-pressure acts against front-side isolating-diaphragm; diaphragm produces micro-deformation proportional to applied pressure.

Silicone-oil filling-fluid uniformly transfers pressure stimulus to internal sensor-core (diffused-silicon or capacitive-sensing-element mainstream).

Sensor-core converts mechanical-pressure input to weak electrical-signal; onboard electronic-circuitry amplification.

Calibration and temperature-compensation delivering linear standard 4–20mA analog-output signal or HART-protocol-capable digital-signal for transmission to plant-automation-system.

Diaphragm-isolation architecture is critical for starch-slurry service: isolating-diaphragm creates complete physical barrier separating abrasive starch-slurry from delicate internal-sensor hardware.

Stop fine-sand/fiber-particle erosion-damage to sensing-core and reduce measuring-port fouling-clogging; greatly extends instrument service-life and stabilizes measurement-reliability.
