Compact gas flow controllers

Vernon Hills, Ill.—Models 32660 and 32661 gas flow controllers adjust flow rates locally with a built-in potentiometer or remotely with a 4-20 mA or 0-5 V dc input signal. Controllers can handle up to 500 psi with a leak integrity of 1310–7 sccs He. All devices feature a straight-tube sensor with restrictor flow element to ensure laminar gas flow for accurate and repeatable resu...

Vernon Hills, Ill.— Models 32660 and 32661 gas flow controllers adjust flow rates locally with a built-in potentiometer or remotely with a 4-20 mA or 0-5 V dc input signal. Controllers can handle up to 500 psi with a leak integrity of 1310–7sccs He. All devices feature a straight-tube sensor with restrictor flow element to ensure laminar gas flow for accurate and repeatable results. Flow rates are said to be unaffected by temperature and pressure variations within limitations. A detachable, tiltable for ease of reading 3.5-digit LCD is included. Cole Parmer Instrument Co.
