Description

The Ametek RK50 Pneumatic Deadweight Tester, 1 to 51 psi, +/- 0.05% Accuracy is a floating ball type, pneumatic deadweight tester. This model is engineered to offer user-friendly features, safe operation, and an optimal performance in the field or in the lab. It produces a pressure by applying force (weight set) over area (the ceramic ball and nozzle). The RK-50 is NIST traceable and accurate to ±0.05% using stainless steel weights calibrated to International standard gravity at 9.80665 m/s2. The RK tester is self-regulating with accuracy independent of the operator, which allows automatic stabilization of weights, eliminating the need to adjust input pressure. This model utilizes a virtually frictionless ceramic ball floating on a layer of air within a stainless steel cylinder. The RK-50 tester features a quick-leveling system for field or lab setup. Setup for the RK50 is completed by simply connecting two tubes; one for the supply and one for the unit-under-test, leveling the RK, and adding the appropriate weights.

  • Range: 1 to 51 psi
  • Increment: 1 psi
  • Weight Carrier and Ball Output: 1 psi
  • Accuracy: ±0.05% of reading
  • Connection: 1/8" Female NPT
  • Repeatability: ±0.005% rdg
  • Temperature coefficient: ±0.00167% of rdg/°C (@ on 23 °C)
  • Pressure Source: Nitrogen or instrument/shop air
  • Max Supply Pressure: 450 psi/3100 kPa
  • Min Supply Pressure: 30 psi/210 kPa
  • Rugged ceramic measuring ball
  • Floating ball supported only by a thin film of air which is virtually frictionless
  • Overhung weight carrier reduces side thrust and friction which lengthens the life of the ball/nozzle and carrier
  • Quick-leveling system for field use
