Hydraulic deadweight tester LDW-HK

Primary standard for defining the pressure scale in a range up to 1,200 bar hydraulic Reference instrument for factory and calibration laboratiries for the testing, adjustment and calibration of pressure measuring instruments Complete, stand-alone system, also suitable for on-site use Special Features: Total measurement uncertainty to 0.025% of measured value Factory calibration includes traceability to national standard; with UKAS calibration possible as an option High long-term stability with recommended recalibration cycle every five years Masses manufactured from stainless steel, can be adjusted to local gravity Compact dimensions Proven primary pressure standard Deadweight Tester / Pressure Balances are the most accurate instrument available on the market for the calibration of electronic or mechanical pressure measuring instruments. The direct measurement of the pressure (p = F / A), as well as the use of high-quality materials enable a very small measurement uncertainty, in conjunction with an excellent long-term stability of 5 years (recommended in accordance with German Calibration Service DKD/DAkkS). The deadweight tester / pressure balance has therefore been used for years in factory and calibration laboratories in national institutes, research laboratories and in industry. Stand-alone operation Due to its integrated pressure generation and the pure mechanical measuring principle, the model LR-Cal LDW-HK is ideal for on-site use for maintenance and service. Basic principle Pressure is defined as the quotient of force and area. The core component of the model LR-Cal LDW-HK is therefore a very pecisely manufatured piston-cylinder-system,
