Panels – Pressure Regulators APAN1 Gas Panel - AGP Assist
series  Application Gas analysis
equipment needs regular calibration. The most common method is using zero- and
span-gas from certified gas cylinders. These gas cylinders
contain high purity zero-gas (for example Nitrogen, or synthetic air) or well
defined gas mixtures for span calibration. To assure proper pressure reduction
(most gas cylinders have a pressure of 150 or 200 bar), to prevent any
contamination and to manipulate safely, Ankersmid offers gas panel - and
point-of-use pressure regulators. Description Wherever
possible the calibration gases are installed outside the analyzer cabinet or
shelter. Ankersmid offers primary pressure reducing panels, allowing easy
installation and handling. The Gas panel ‘APAN1’ includes a stainless steel
mounting plate, the first stage pressure regulator with in-and outlet
manometers, gas outlet diaphragm valve, overpressure relief valve and a 1 meter
pressure flexible with appropriate cylinder valve connection (DIN 477). Inside
the analyzer cabinet a finely adjustable point-of-use regulator assures precise
gas dosing .The regulator allows immediate control of the calibration gas
without the need of checking the outside cylinder settings. The Ankersmid
Pressure Regulator (APR) uses a bellow type diaphragm, which allows sensitive
outlet pressure control (0-1 bar) with a low torque multiple turn adjusting
knob. Using this combination of first
stage (outside) and second stage (inside) regulators assures very stable gas
pressure, even at low cylinder pressure. (One stage regulators show an
increasing secondary pressure when the gas cylinder pressure drops, creating
unacceptable calibration flows or even causing damage to the analyzer).
