An automated, two channel sequencer automatically starts the air flow after the 5 minutes soak time, after 5 minutes stops the air flow aatm sounds an alarm, and again sounds an alarm after the 10 minutes settling period other times are also available.

Two channel digital flow control unit, upgrade from rotameter incl. Test assembly includes 1 of each: Also displayed is the time remaining to the next test event requiring operator attention.

Model uses a digital indicating 0. An automated, two channel sequencer automatically starts the air flow after the 5 minutes soak times, after the 6 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. Also provided is a digital display time counter showing remaining seconds to the next even requiring operator attention.

Work Item s – proposed revisions of this standard. The Autowasdh is suitable for use with air inlet tubes of differing lengths and diameters.

It is equipped with a two channel automated sequencer, a two channel mass flow controller, and four temperature probes for the measurement of the sample temperatures. PAO fluid has longer life at higher temperatures then conventional bath medium oils. Also displayed is the time remaining to the next test event requiring operator attention.

Two channel digital flow control unit, upgrade from rotameter incl. Replaces silicones as heated bath medium. 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.

Also displayed is the time remaining to the next event requiring operator attention. You can select a total of 10 programmes from the controller allowing you the choice of a single or two solvent wash with cycle times ranging from 3 to 19 minutes.

Foaming Characteristics of Lubricating Oils – ASTM D, D | Lawler Manufacturing

Model 24 dual foam test bath is qstm traditional arrangement with two glass jars mounted on a supporting base. Home Products Contacts Search Catalog. Automatic controller, upgrade, same as FM-9 but specifically to upgrade owners of Lawler Model Designed for pumping cold liquid to cool Model or H air foam bath. Silicone fluids are not aatm. Automatic-sequencing controller, automatically starts air flow after the 5 minute period of soaking the diffuser, sounds alarm and automatically stops air flow after 5 minutes blowing period, and sounds alarm after 10 minute settling period.

One channel totalizer installed in Model baths. The chilled mixture is also helpful for rapid cool down of the air chamber for the next test.

Air supply assembly mounted on a base with as air supply pump FM and with an air drying tower FM A multi-pane insulated window allows full xstm of the test cylinder for observation of the foam. Standard test method for high temperature foaming characteristics of lubricating oils. Once you start a programme you can leave the Autowash unattended and the instrument sounds an audible warning when the cycle has finished.

Novel, sophisticated heating system and control allows the sample to reach test temperature in less than the 60 minutes specified by the astk. Typically ml of solvent is required. Means of empirically rating the foaming tendency and the stability of the foam are described. Flow cooler used with Aatm 24 and 28 liquid baths.

For improved aztm of results, two digital indicating mass air flow controllers are used for precisely measuring and controlling the amount of air delivered to the air diffuser.

Table for air bath with FM chiller. A touch screen allows the operator selection and full adjustment of all test parameters. Benefits at a Glance Available as twin-bath arrangement Four test places in each bath Temperature of d8892 bath can be maintained individually Convenient Operation Digitally-indicating circulation thermostats with cooling coil, temperature probe and self-optimizing electronic heating control Borosilicate satm 20 L with leakage protection vessels Test equipment for 2 test places per bath included Customized User Flexibility Different gas diffusers: Model 28 is similar to Model 24 but upgraded for semi automated operation for increased precision and operator assistance.

Two channel totalizer installed in Model baths. Use of silicone oils is not recommended since only a few parts per million contamination will distort the foam results. Both results are automatically displayed on the computer screen. For specific warning statements, see Sections 78and 9.

Mechanically refrigerated bath 12 liters with a digital indicating controller. An automated, two channel sequencer aatm 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.

Furthermore, the traditional analog flow meter is replaced by a digital mass flow meter that directly interacts with the software. Recommended when using your own desiccant. 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.

Inadequate lubrication, cavitation, and overflow loss of lubricant can lead to mechanical failure. 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.

Foaming Characteristics: Foam Tester

Caution should be taken when handling mercury and mercury containing products. Available as a stand alone model or incorporated into any of the foam testing baths. Especially in high-speed gearing and high-volume pumping systems, the tendency d8892 oils to foam can lead to inadequate lubrication or cavitation which may result in mechanical failure.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. 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. Model uses a digital indicating 0. Fan assembly for quicker cooling of Model baths.
