PORTABLE PRESSURE SOURCE FOR AIR TESTING WESIVO 521 is a hand-operated pneumatic pressure pump for calibration and verification of pressure gauges and pressure instruments. It supports positive-pressure and vacuum operation through a pressure/vacuum conversion valve, pre-pressure lever, release valve and fine-adjustment handwheel. Connect the reference and test instruments at the instrument port and adjust to the required test point. OPERATING RANGE AND CONSTRUCTION The supplied manual specifies a pressure range of -0.095 to 6 MPa, air as the pressure medium, 0 to 50 °C operating temperature, less than 85% humidity, 10 Pa adjustment fineness, a safety pressure below 120% of full scale, dimensions of 383 × 235 × 173 mm and an approximate weight of 3.6 kg. The manual does not specify a pressure accuracy class; accuracy depends on the reference instrument and the complete test setup. POSITIVE PRESSURE AND VACUUM Pull out or push in the pressure/vacuum conversion valve for the required test mode, use the pre-pressure lever to approach the test point and use the fine-adjustment handwheel for final adjustment. Release pressure before changing between pressure and vacuum modes. REQUEST A CONFIGURATION REVIEW Send the reference gauge, test instrument, required test points, connection details, quantity and delivery country. Confirm the local atmospheric pressure when specifying the vacuum requirement. Use the supplied manual for operating precautions and maintenance guidance.
