The use of heated air to heat the test samples improves the overall safety by eliminating the use of the potentially unsafe, smoking, dripping of, flammable, hot liquid bath medium. Air supply pump and surge tower FM with air drying tower FM assembly. Home Products Contacts Search Catalog.
Furthermore, the traditional analog flow meter is replaced by a digital mass flow meter that directly interacts with the software. Benefits at a Glance Available as twin-bath arrangement Four test places in each bath Temperature of each bath can be maintained individually Convenient Operation Digitally-indicating circulation thermostats with cooling coil, temperature probe and self-optimizing electronic heating control Borosilicate jars 20 L with leakage protection vessels Test equipment for 2 test places per bath included Customized User Flexibility Different gas diffusers: Even low levels 1 ppm and above of silicone contamination interfere with test results.
Two channel digital flow control unit, upgrade from rotameter incl. The Autowasdh is suitable for use with air inlet tubes of differing lengths and diameters. Automatic controller, upgrade, same as FM-9 but specifically to upgrade owners of Lawler Model Long temperature probes are provided for each of the 4 test positions for digital control and test sample temperature display and precise temperature control during the foaming process.
Mechanically refrigerated bath 12 liters with a digital indicating controller. PC controlled apparatus visual first bubble detection.
During cleaning an enclosed system is used to draw solvent and air through the diffuser in one direction which avoids particles or used solvent entering the diffuser and blocking the pores. Available as a stand alone model or incorporated into any of the foam testing baths.
Also displayed is the time remaining to the next event requiring operator attention. Certified Mott metal cylindrical gas diffuser more uniform air bubbles and greater precision than Norton. Inadequate lubrication, cavitation, and overflow loss of lubricant can lead to mechanical failure.
The two channel automated sequencer automatically starts the air flow after the required 5 minutes of gas diffuser stone in the test sample, stops the air flow after 5 minutes, signals the operator to view the foam height, and after 10 minutes again signals the operator to again observe the collapsed foam level. Conventional bath fluids darken and require frequent replacement.
Flat bottomed glass mL graduated test cylinder starting at 10mL and continuing at 10mL increments. An automated, two channel sequencer automatically starts the air flow after the 5 minutes soak time, after 5 minutes stops the air flow and sounds an alarm, and again sounds an alarm after the 10 minutes settling period other times are also available.
Foaming Characteristics of Lubricating Oils – ASTM D892, D6082
Four position sample storage rack cylinders not included. Flow cooler used with Model 24 and 28 liquid baths. Get in touch Document Finder. Typically ml of solvent is required.
The Autowash is a bench top unit which automatically cleans and dries Mott and Norton diffusers using one or two solvents without removing the air tube. Foam Tester The foam tester allows the determination of the foaming characteristics of lubricating oils at astj temperatures by empirically rating the foaming tendency and the foam stability.
Autowash for ASTM D, IP
A multi-pane insulated window allows full view of the test cylinder for observation of xstm foam. Copyright Stanhope—Seta Limited PAO fluid has longer life at higher temperatures then conventional bath medium oils. Test assembly includes 1 of each: Silicone fluids are not recommended. The chilled mixture is also helpful for rapid cool down of the air chamber for the next test.
All key parameters are displayed during the test. One channel totalizer installed in Model baths. An automated, two channel sequencer automatically starts the air flow after the 5 minutes soak time, after 5 minutes stops the air flow and sounds an alarm, and again sounds an alarm after the 10 minutes settling period other times are also available.
Test assembly includes 1 of each: Seta Autowash Part Number The Autowash is a bench top unit which automatically cleans and dries Mott and Norton diffusers using one or two solvents without removing the air tube.
Both results are automatically displayed on the computer screen. Especially in high-speed gearing and high-volume pumping systems, the tendency of oils to foam can lead to inadequate lubrication or cavitation d82 may result in mechanical failure.
However, the manometer is replaced by a high precision digital pressure controller. For improved consistency of results, two digital indicating mass air flow controllers 8d92 used for precisely measuring and controlling the amount of air delivered to the air diffuser.
Even low levels 1 ppm and above of silicone contamination interfere with test results. Sealing washer for between inlet tube and diffuser.
