CAL2K Bomb Vessel Facts

The CAL2K calorimeter from Digital Data Systems has a revolutionary vessel. The vessel features safety standards, data tracking requirements and reliability.

The vessel is the heart of the calorimeter and features a printed circuit board containing : a microprocessor, memory, temperature sensors and other electronics, which are built into the base of the unit.

The solid-state temperature sensors are strategically placed around the outer wall of the vessel and are embedded into the aluminium "skin" of the unit. The position of the sensors integrates the various temperature readings obtained from the outer surface of the stainless steel core. The way in which a sample burns causes a varying heat pattern transfer to the core.

An added benefit is that the memory of the unit is permanent, requiring no battery to retain the data.

As there are no serviceable parts in the electronics of the vessel (they are all surface mount devices) the board is fully encapsulated in resin. This ensures that the electronics are protected from both moisture and any mechanical damage. All the information required to operate the vessel is stored in its own memory.

The memory of the vessel can store the following data : Manufacturing data and serial number, reconditioning data, customer data, firing count, maximum temperature and status.

The manufacturing data and serial number, reconditioning data and customer data can only be entered or changed by Digital Data Systems at their factory. The customer cannot change this in any way - this is for safety reasons.

The firing count keeps track of the number of firings that the vessel has done since manufacture or the last reconditioning. Once this count reaches a pre-set level (factory set is usually 5000) the vessel is "turned off" and prevented from doing any further firings until it has been inspected and/or reconditioned. This is done by an authorized service engineer and after inspection; the service engineer can extend the pre-set level if the vessel is found to be in a serviceable state. If the vessel is reconditioned the counter is reset and the date is entered into the vessel memory. Once again the customer cannot change the count in any way - this is for safety reasons. A warning is displayed when the count is near to the pre-set turn off level.

The CAL2K range has been upgraded to the CAL3K bomb calorimeter range using the CAL3K Oxygen Bomb Vessel. Although the CAL2K bomb vessels are still applicable, it might become obsolete in the future.
