ASTM D892,D6082 Digital Diffuser Certification Apparatus for Foam Testing of Lubricating Oils
FORZA Model FM-DCA Digital Diffuser Certification Apparatus for Foam Testing of Lubricating Oils.
The measurement of Foaming Characteristics of Lubricating Oils per ASTM D892 foam testing, and ASTM D6082 High Temperature Foam Testing, is dependent upon the gas diffuser stone used in the test. Calibration of the diffuser stone involves the determination of critical parameters including PORE DIAMETER and PERMEABILITY for either spherical ceramic (Norton stone) or cylindrical metal (Mott) diffusers.
ASTM D892 recommends that the diffusers be tested when new and periodically thereafter, preferably after each use. It is, however, strongly recommended that the recalibration of the diffuser be done every 10 tests since plugging occurs after use even with diligent cleaning. Model FM-DCA, with Windows Operated In-built computer with Touch screen,automatically determines both diffuser PORE DIAMETER and PERMEABILITY in accordance with ASTM E128. A high precision digital pressure controller replaces the traditional manometer. Furthermore, the traditional analog flow meter is replaced by a digital mass flow meter that directly interacts with the software. The first bubble is detected and the pressure ramping is automatically controlled The automated pressure ramping profile generates the Dynamic Bubble Point pressure that is used to determine Pore Diameter of stainless steel and ceramic diffusers. The software program calculates this.
The steady pressure holding profile generates the permeability of the diffuser in mL/min. Both results are automatically displayed on the computer screen. The FORZA proprietary Windows software manages the testing operation and all the data. Operator name & Stone ID can be stored and managed by the software. The data can be printed and/or stored on the PC hard drive for ISO 9000 trace ability.
‘’Instrument is comes with 1 year calibration certificate, for the future calibration of pressure and flow, we can provide you a Portable Pressure calibrator and a Flow meter with an additional cost’’.
