Equipment Overview
Here's How It Works
The tester consists of an electrical system, a temperature sensing system, and a special flask with water/antifreeze cooled condenser. The sample to be tested, approximately one ounce (30ml) - is introduced through a funnel in the top of the instrument. The test sample then flows down through a double U-shaped tube. The weight of the falling fluid creates a siphon, drawing the remaining fluid into the flask, and then breaking the siphon. Any remaining fluid in the condenser and exit tube will be carried over by air bubbles, produced when the siphon is broken.
Precise sample size results from relative sizes of the flask and the U-shaped tube. The tube contains precisely half the volume in the flask. The siphon technique makes the instrument self-purging so that any new sample will not be affected by a previous sample, and manual cleaning is not required.
An integral flask heater and anti-bumping coil heats the brake fluid for a time interval indicative of reflux equilibrium.
Simple Controls
The new MBT-500 Manual Boiling Point Tester uses a micro controller to control all functions of the test. These include simultaneously display of the temperature in both Celsius, and Fahrenheit, test sequence including Cooling, Fill, Test, and Read Final Boiling Point. The micro controller provides a countdown timer for the cooling (3 minutes) and testing cycle (10 minutes). At the end of the testing cycle, the final boiling point will be held in memory, a buzzer will sound for 1 second, and the testing cycle will automatically shut down. The operator can get his reading later at any time.
The MBT-500 has three push buttons for control. One for Power ON I/O, a Testing Button to start the test, and a reset button to clear the display once the final boiling point has been recorded at the end of the test cycle.
The MBT-500 Manual Boiling Point Tester replaced our MBT-360 Manual Boiling Point Tester.
In Use In Many Plants
These systems are designed by a chemical engineer who has been employed in the brake systems manufacturing industry for nearly forty years. His systems are in use in many automotive assembly plants word-wide for production line testing.
