JY Hydraulic Dead Weight Tester Pressure Calibrator With Tungsten Carbide Piston

Description JY Series Digital Piston Pressure Gauge Dead Weight Tester

The JY Series Digital Piston Pressure Gauge (Dead Weight Tester) represents our newly developed product, engineered in full compliance with the latest national verification regulation for piston gauges (JJG59-2007). Key components of the piston system are constructed from tungsten carbide, a material selected for its exceptional hardness and low linear thermal expansion coefficient. This significantly enhances the wear resistance of the piston and ensures negligible deformation under pressure, resulting in highly stable performance.

The device utilizes dioctyl sebacate as the pressure-transmitting medium, which contributes to its superior measurement sensitivity. Through the integration of advanced materials, innovative technologies, and refined manufacturing processes, the technical specifications of this new piston gauge have been substantially improved. Consequently, it is ideally suited for the calibration and testing of a wide range of pressure instruments, including digital pressure gauges, precision pressure gauges, pressure transmitters, and pressure sensors.

Dead Weight Tester (JY Series) - Product Overview

The JY Series Piston Gauge represents our next-generation dead weight tester, engineered for precision pressure calibration in laboratory environments. Manufactured in full compliance with the JJG59-2007 national verification regulation, this instrument sets new standards in accuracy and reliability for calibrating pressure transfer standards and electronic pressure measuring devices.

Technical Features:

1. Advanced Piston Material
   The piston-cylinder system is precision-machined from tungsten carbide, delivering exceptional strength, rigidity, and minimal thermal expansion. This ensures stable performance across wide ambient temperature ranges, with optimal operation at 20±5°C.

2. Optimized Load Application
   Features a low-center-of-gravity design where weights are directly applied through a cradle mechanism. This ensures smooth piston operation with minimal pressure fluctuation, resulting in highly accurate readings.

3. High-Pressure Performance
   When measuring pressures exceeding 25 MPa, the system utilizes low-viscosity dioctyl sebacate as the pressure-transmitting medium, guaranteeing superior measurement sensitivity.

4. Non-Magnetic Construction
   All precision weights are manufactured from non-magnetic stainless steel, eliminating magnetic interference and ensuring long-term stability.

5. Intelligent Position Monitoring
   Integrated piston displacement sensor continuously monitors piston position within ±1.5mm vertical travel range, providing real-time visual feedback through a responsive display system.

6. Extended Measurement Range
   Covers an extensive pressure range with fundamental error of ±0.02% or ±0.05% at the lower 1 MPa range. The KY100 configuration achieves upper limits of 6/60/100 MPa, representing the current domestic performance benchmark.

7. Effortless Pressure Control
   Simplified pressure adjustment mechanism enables smooth operation across the entire range, maintaining ease of use even at maximum 250 MPa capacity.

Application Scope:
Ideal for calibration of digital pressure gauges, precision pressure instruments, pressure transmitters, and various pressure sensors requiring laboratory-grade accuracy.
