Explore our top-tier CE-certified dual-function measurement devices engineered for extreme hydraulic, automotive, and heavy-industrial operational environments.
In modern heavy-duty combustion engines, industrial hydraulic power units (HPUs), and high-performance racing platforms, real-time monitoring of fluid mechanical status is critical. A CE Certification Oil Pressure Temperature Gauge Dual integrates two distinct sensing mechanisms into a singular compact dial face plate or digital display enclosure. This integration saves panel space, reduces fitting leakage paths, and provides immediate visual correlation between fluid kinetic pressure and thermal expansion dynamics.
Utilizing high-grade C-type Bourdon tubes crafted from Phosphor Bronze or AISI 316L Stainless Steel, combined with piezoresistive silicon transducers. Operating across 0-10 Bar (0-150 PSI) ranges with an intrinsic accuracy class of Class 1.0 or Class 1.6 as per EN 837-1 standards.
Incorporating direct-mounted bimetallic helices or remote capillary NTC thermistors/PT100 RTDs. Thermocouple or capillary line lengths span up to 3 meters, measuring thermal fluctuations from 0°C to 150°C (32°F to 300°F) with rapid thermal response times (<2.5 seconds).
Dual gauges are filled with 99.5% pure industrial Glycerin or High-Viscosity Silicone Fluid (1000 cSt). Liquid filling eliminates pointer flutter induced by engine vibration cycles, lubricates internal gears, and prevents internal condensation under high humidity.
Manufactured with IP65 to IP67 ingress protection. Stainless steel crimped or bayonet bezel rings ensure zero-leak operation even when subjected to sudden pressure spikes up to 130% of full-scale value.
Over 20 years of continuous research, manufacturing excellence, and compliance with rigorous international metrology protocols.

Procuring CE-certified dual oil pressure and temperature gauges direct from Huzhou Accuracy Instrument Co., Ltd. provides distinct structural cost efficiencies, technical customization flexibility, and enterprise reliability for international distributors and Original Equipment Manufacturers (OEMs).
With 20 specialized R&D engineers on site, we provide rapid prototyping for custom dual-dial graphics, specialized thread adaptors, electronic signal outputs (4-20mA, 0-5V, RS485 Modbus), and custom sensor housing footprints within 14 business days.
Our 3,000 square meter manufacturing plant utilizes automated laser scale etching and multi-point automated pressure/temperature calibration benches. Every dual gauge undergoes 100% full-cycle fatigue testing prior to liquid filling and packaging.
Our internal testing facility performs environmental chamber testing (-40°C to +125°C), salt spray corrosion resistance (96 hours ASTM B117), harmonic vibration testing (EN 60068-2-6), and burst pressure verification to guarantee ZERO-LEAK performance.
Exporting pressure and temperature measuring instruments into Europe, North America, and Asia-Pacific markets demands strict compliance with legal frameworks. Our dual gauges carry complete documentation for seamless import clearance and system integration.
Our dual pressure and temperature gauges comply with Sound Engineering Practice (SEP) and Category I/II assessments under the European PED, guaranteeing structural integrity under continuous pressure cycles.
For hybrid dual gauges with digital readouts or micro-controller sensors, our products feature robust Electromagnetic Compatibility (EMC), resisting RF interference and electrostatic discharge (ESD up to 8kV).
All component materials—from the brass housing, stainless steel capillary lines, lead-free solder points, to dial face inks—strictly conform to EU RoHS 3 (Directive 2015/863) and REACH SVHC chemical safety norms.
Each unit features laser-engraved serial numbers or batch barcoding, allowing 100% component-level traceability from raw material brass billets to final calibration test certificates.
As industrial automation shifts toward Industry 4.0 and smart diagnostic fleet management, fluid measurement systems are evolving beyond standalone mechanical pointers.
Modern dual gauges now incorporate Bluetooth Low Energy (BLE) or LoRaWAN communication modules. Engineers can monitor oil temperature and pressure curves remotely on mobile devices or cloud dashboards without physical panel access.
Combining traditional mechanical needle movements (for zero-power emergency visibility) with high-contrast sunlight-readable digital OLED sub-screens for precision decimal tracking.
Transitioning from multi-wire analog harnesses to single CAN-bus (J1939) or LIN-bus protocols, simplifying vehicle wiring looms in natural gas vehicles (CNG/LNG) and heavy-duty earthmovers.
Development of synthetic fluorinated damping fluids that maintain stable viscosity across extreme operational envelopes (-50°C sub-arctic machinery to +220°C superheated turbine hydraulics).
Our dual measurement instruments are deployed globally across diverse industrial, mobile, and hazardous environments:
Installed in high-RPM performance engines to detect oil breakdown instantly. As engine oil heats up, viscosity drops, leading to critical pressure loss. A dual gauge allows drivers to see temperature-pressure correlation on one dial face.
Integrated into alternative fuel delivery systems where monitoring both natural gas/oil pressure line integrity and thermal ambient conditions prevents vapor lock and regulator freezing.
Seal-tight stainless steel capillary dual gauges placed on heavy marine diesel engines, providing continuous readings resilient to salt spray corrosion and engine deck vibration.
Used in industrial stamping presses, injection molding equipment, and construction excavators to protect hydraulic pumps from fluid cavitation caused by overheating oil.
Specialized dual gauges monitoring dielectric insulating oil pressure and core oil temperature inside SF6 and oil-immersed power station equipment.
Sanitary dual capillary gauges with tri-clamp fittings used in pharmaceutical and food-grade fluid movement, ensuring thermal sterilization standard compliance.
