S3000 SERIES HYDRAULIC DEADWEIGHT TESTERS

Hydraulic Deadweight Tester. Range to 20,000 psi,  accuracy  up to ±0.015%.

S3000 Series Hydraulic Deadweight Testers.
Pressure ranges:
Oil operated:                 Ranges to 20,000 psi (1400 bar)
Distilled water operated: Ranges to 10,000 psi (700 bar)
The S3000 Series is the culmination of over 50 years experience in the production and design of primary
pressure standards. With features designed to improve accuracy and performance, increase reliability and simplify operation these deadweight testers can be used to calibrate virtually any pressure sensing device, including transducers, transmitters, gauges or pressure switches.

  • Pressure ranges to 20,000 psi (1400 bar)

  • Accuracy better than 0.025% of reading.

  • Increased accuracy option of 0.015%

  • Dual vacuum/pressure models available

  • Psi, bar, kgf/cm2, kPa and MPa ranges available

  • Piston/cylinder design provides stability and repeatability

  • High quality needle valves provide optimum control

  • Mounted spirit level and adjustable feet

  • Improved case with spring-loaded latches for hood

  • Sturdy weight box with hinged lid and side
    handles for easy transport

Each deadweight tester is supplied with a detachable lid that makes it neat, compact, and easily portable. The weight masses are stored in a high-quality case with a self-locking mechanism to protect them during transit. All DWTs are provided with a traceable certificate of accuracy, weight mass details, 1/8, 1/4, 3/8, and 1/2 NPT or BSP female adaptors, operating fluid (where applicable), and spare seals.
