A unique part of the CLEO Detector at CESR is the pressurized wire proportional chamber system for particle identification using measurements of ionization loss (dE/dx) in gaseous argon. Each particle traverses the ~80cm thick detector and leaves 117 ionization samples. Data obtained from ee~ collisions at CESR in the lOGeV center of mass energy region have been analyzed. Initial results showing the most probable ionization loss of hadrons and leptons as a function of their momenta will be presented. Also we describe the geometrical, mechanical and electrical construction of this device.
