Redundant Pressure Sensor

The SG-A23 series Redundant Pressure Sensor is specifically designed for hydraulic pressure measurement applications. It adopts a pressure sensing chip based on Silicon-On-Insulator (SOI) technology, which converts the measured hydraulic pressure into a raw electrical signal. This signal is then processed through a dedicated analog temperature compensation and signal amplification circuit, ultimately delivering a standard current output (e.g., 4-20mA, a widely accepted industrial standard).

overpressure sensor features include a wide operating temperature range and high measurement accuracy, ensuring reliable performance across extreme thermal conditions. The sensor features a coaxial design where the electrical connection port aligns with the pressure interface, optimizing spatial layout and installation convenience. On-site mounting is achieved via flange fixation, complementing its compact and space-saving structure-ideal for integration in equipment with limited installation space.

Boasting exceptional reliability, the sensor incorporates an isolated sensing element and an all-metal hermetic package design, which not only enhances structural robustness but also extends the operational lifespan. Rigorously validated through a comprehensive suite of environmental tests (including temperature shock, vibration, humidity, and corrosion resistance evaluations), the product fully complies with stringent aviation industry standards. Its robust construction enables compatibility with a broad range of hydraulic media (such as mineral oil, synthetic hydraulic fluids, and water-glycol mixtures) and ensures long-term stable operation even in harsh working environments-including high pressure, extreme temperatures, and high-vibration conditions commonly encountered in industrial and aerospace applications.

* Redundant & Safe Design - All-metal, isolated sensor structure ensures high reliability and long working life under harsh conditions.

* Wide Operating Temperature & Environmental Tolerance - –55 °C to +125 °C operating window covers harsh climates, industrial heat, or cold-storage environments.

* High Pressure Capability - Up to 28 MPa nominal, 32 MPa overload, 52 MPa burst: suitable for hydraulic, oil, fluid pressure systems.

* Media Compatibility & Material Robustness - Wetted parts in 316L stainless steel, supporting various fluids or gases, including aggressive hydraulic media.

* Standard Industrial Output (4–20 mA) - Easy integration with most control systems, PLCs, data acquisition modules.

* Compact & Flange-Mountable Structure - Electrical connection in same direction as pressure port, suitable for compact installations and retrofit.

* Long-Term Stability - Specified drift ±0.1% F.S./year supports long maintenance intervals for continuous monitoring systems.

Note: Because SG-A23 is designed for industrial/hydraulic use, please specify the fluid or gas media when requesting quotation to ensure material compatibility and sealing integrity.

Reliability & Environmental Robustness

SG-A23 is engineered for long-term deployment in demanding environments. Its all-metal construction and isolated sensing architecture provide:

* High corrosion resistance (suitable for hydraulic fluids, oils, water, inert gases)

* Thermal stability across wide temperature swings

* Pressure overload & burst margin for safety under transient conditions

* Stable long-term performance, minimizing drift and maintenance needs

These traits make SG-A23 especially suitable for hydraulic systems, oil & gas equipment, industrial fluid systems, aerospace ground support, and other applications where reliability and safety are paramount.

* Hydraulic systems (oil pressure, fluid power, hydraulic actuators)

* Fuel / oil pressure monitoring in engines or heavy machinery

* Industrial fluid systems (water, hydraulic oil, inert gases)

* Training rigs, test benches requiring redundant pressure feedback

* Aerospace ground equipment requiring robust, stable sensing

* Industrial automation & process control with legacy 4–20 mA systems

When placing an inquiry or order, please confirm:

* Required pressure range (≤ 28 MPa)

* Fluid or gas medium (oil, water, hydraulic fluid, inert gas, etc.)

* Operating temperature range & ambient conditions

* System supply voltage (14–32 V DC supported)

* Mechanical interface requirements (mounting flange, port type)

* Output termination preferences (connector type, cable, shielded, etc.)

* Required quantity - small sample or batch production

Providing complete application context helps ensure the sensor meets your system integration needs.
