Pneumatic deadweight tester LDW-P

Primary standard for defining the pressure scale in a range up to 100 bar pneumatic Reference instrument for calibration laboratories and factory for the testing, adjustment and calibration of pressure measuring instruments Self-contained, complete, stand-alone system, also suitable for on-site use Special features: Total measurement uncertainty down to 0.008% of measured value Factory calibration includes traceability to national standars, as standard. Optional with DAkkS calibration High long-term stability with recommended recalibration cycle every 5 years Masses manufactured from stainless steel and aluminium, local gravity adjustment possible at no additional charge The optional quck-change system of piston-cylinder system enables fast and secure exchange of the piston-cylinder system in order to change the measuring range without tools. 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 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-P is ideal for on-site use for maintenance and servic
