Pressure Sensor/Leak Detection | CAL3K Features

APPLICABLE TO CAL3K-AP ONLY


The CAL3K-AP with automatic oxygen filling monitors the vessel pressure and reports on any leak.

If a leak is detected during the initial phase, then the determination is terminated.

If a leak is found during the main phase, then the result is ‘flagged’ accordingly.


The initial and main period leak detection points can be set from the keyboard. It is normal that the filling pressure decreases during the initial and main periods.

START A CALIBRATION

The calibration of the CAL3K is a process in which a substance (Benzoic Acid, BA) of known calorific value is burned so that future burning of unknown substances can be compared to it. In other words the calibration records all the system variables such as temperature rise and heat loss in memory. All this data is called a calibration field. The calibrations are stored in the vessel.

PERFORMING A CALIBRATION

To perform a standard calibration using Benzoic Acid Tablets you will need: A working oxygen bomb calorimeter system connected to a power source, A CAL3K Manual Oxygen Filing Station connected to an oxygen supply (not needed when using the CAL3K-AP Calorimeter)...

INTELCAL SYSTEM CALIBRATION

The CAL3K system uses two calibrations: Keyboard calibration, in real time, one sample, average with last ‘n’ calibrations, PC calibration, in retrospect, multiple samples. The PC calibration is called ‘IntelCal’ because of its complexity and system effectiveness.
