Parker SCG-250-A SCG Pressure Sensor 0-250 bar

The Parker SCG-250-A is a SCG screw-in compact pressure sensor / gauge with a 0-250 bar measuring range from Parker Hannifin's Instrumentation / SensoControl product group, engineered for accurate pressure measurement in hydraulic and process systems. Parker Hannifin is the world's largest motion and control technology company, and its SensoControl range is the recognised standard for diagnostic and continuous pressure measurement on hydraulic machinery. The SCG-250-A provides a 4-20 mA / switch output (variant) output proportional to system pressure across a 0-250 bar range, enabling closed-loop control, condition monitoring and predictive maintenance on the hydraulic and process equipment that runs Saudi Arabia's industrial base. Razz Middle East stocks Parker instrumentation in Jeddah, Riyadh and Dammam for fast delivery and full application support to ARAMCO, SABIC, SWCC and NEOM projects.

Technical Architecture & Design

The SCG-250-A is part of Parker's SensoControl family of screw-in pressure sensors, offering a 4-20 mA / switch output (variant) output across a 0-250 bar measuring range from a compact, rugged stainless-steel package. The SCG-250-A uses a robust stainless-steel measuring cell with a thin-film or piezoresistive sensing element bonded to the pressure diaphragm, converting pressure-induced strain into a precise, temperature-compensated electrical signal. The all-welded stainless-steel wetted parts give excellent media compatibility with hydraulic oils, water-glycols, fuels and many process fluids, while the compact screw-in body installs directly into a measurement port without additional adapters. Integrated signal conditioning provides a calibrated, linearised and temperature-compensated output, and the sensor is designed to withstand the pressure spikes, vibration and temperature cycling typical of hydraulic systems. Robust EMC protection and wide-range reverse-polarity and over-voltage protection make the SCG-250-A suitable for the electrically noisy environment of mobile and industrial machinery.

Performance Specifications

Headline data: measuring range 0-250 bar; output 4-20 mA / switch output (variant); accuracy typically <= 0.5% of full scale; compensated temperature -25 to +85 C; high burst-pressure margin and over 10 million pressure cycles. These figures are taken from the Parker SensoControl datasheet and are validated across the compensated temperature range. The SCG-250-A delivers high accuracy and long-term stability, with fast response that captures the dynamic pressure events — spikes, ripple and transients — that reveal the health of pumps, valves and accumulators. The compact stainless body, high burst-pressure margin and high cycle endurance ensure reliable service in continuous hydraulic duty. The product carries CE marking and the relevant international certifications, ensuring acceptance under SASO import requirements and compatibility with Saudi Aramco and SABIC instrumentation standards.

Industrial Applications in Saudi Arabia

Across the Kingdom the Parker SCG-250-A provides the pressure measurement that keeps critical systems safe and efficient. Saudi Aramco upstream and downstream facilities use SensoControl transducers for hydraulic power-unit monitoring, pump-discharge and filter-differential measurement, accumulator pre-charge verification and condition-based maintenance on drilling, workover and process equipment. SABIC, Sadara and Petro Rabigh petrochemical plants apply the SCG-250-A to monitor hydraulic presses, extruders, injection-moulding machines and process-skid pressures, feeding the signal into PLC and DCS control loops. SWCC and ACWA Power desalination facilities use it for high-pressure pump and membrane-rack pressure monitoring, while MAADEN mining operations deploy it on crusher, conveyor and excavator hydraulics. Machine builders, OEMs and maintenance contractors at NEOM, Red Sea Global and across Riyadh, Jubail and Yanbu specify the SCG-250-A for closed-loop hydraulic control, energy optimisation and predictive-maintenance systems, where accurate, reliable pressure data prevents unplanned downtime and extends equipment life in demanding Gulf conditions.

System Integration & Wiring

The SCG-250-A provides a 4-20 mA / switch output (variant) signal on a M12 4-pin connector, suitable for direct connection to PLC analogue inputs, Parker hydraulic-monitoring units and DCS systems. The SCG-250-A installs into a standard pressure port and connects to PLC analogue inputs, hydraulic-monitoring units (such as Parker SCM/Service Master) or DCS systems. Correct selection of pressure range (to keep the working point in the optimum part of the span), electrical connection, sealing and over-pressure protection ensures accurate, long-life measurement; Razz provides this application engineering in-Kingdom together with calibration documentation.
