JY series Digital pressure gauge piston dead weight tester calibration for oil industry with 100Mpa high pressure
Description of JY series dead weight tester
JY Series Digital Pressure Gauge Calibration with 100MPa Piston Deadweight Tester for Oil Industry** Developed per JJG59-2007 standards, the JY Series piston pressure tester features tungsten carbide piston components—high-hardness, low-thermal-expansion—to ensure minimal deformation under pressure and stable performance. Using low-viscosity isooctyl sebacate as the medium, it achieves high sensitivity even at 100MPa. This new-design tester enhances technical metrics via advanced materials and technology, ideal for calibrating digital pressure gauges, transmitters, sensors, and precision instruments in high-pressure oil industry applications.

Features & Application
1. Precision Components:
The piston-cylinder assembly, crafted from high-strength carbide tungsten carbide with low thermal expansion, ensures stable operation across a wide temperature range (optimal at 20 ± 5 ℃).
2. Enhanced Accuracy:
With a low center of gravity, weights act directly on the piston, minimizing pressure fluctuations and enabling precise readings.
3. High-Pressure Performance:
For pressures exceeding 25MPa, low-viscosity isooctyl sebacate as the medium boosts sensitivity, ensuring reliable measurements.
4. Quality Materials:
Weights made from non-magnetic stainless steel prevent interference, while a piston displacement sensor maintains accurate positioning within ± 1.5mm.
5. Versatile Range & Adjustability:
Covering 1MPa to a domestic-leading 100MPa with ± 0.02%–0.05% accuracy, it allows effortless pressure adjustment even at 500MPa.
