With the diversification of the application needs of liquid nitrogen containers, but also scientific and technological progress, these biological containers, in addition to the traditional open-top canisters + basic sample freezing, there are also access to the automatic monitoring system + intelligent sample freezing management of the intelligent vapor-phase liquid nitrogen cryogenic tanks, the upgraded version and divided into more than 350 liters of large-capacity and more than 65 liters of conventional laboratory capacity.

So what does this upgraded automatic monitoring system for vapor phase liquid nitrogen cryogenic tanks warn of?

There are three main areas: one level, two temperature, and three abnormal operation!

I.Liquid level

The level warning for vapor phase liquid nitrogen cryogenic tanks is equivalent to an intelligent level alarm retrofitted to conventional liquid nitrogen containers.

As long as the standard value is preset in advance, an early warning will be issued when the liquid level is higher or lower than this value, through the form of sound and light + SMS, the system can also be connected with the liquid nitrogen replenishment tank to automatically replenish the liquid when the liquid level is too low, and stop replenishing the liquid when it reaches the standard value.

II.Temperature

In addition to the monitoring of the liquid level, the vapor-phase liquid nitrogen cryogenic tank automatic monitoring system has a temperature warning, the same is self-set high temperature A high temperature B and low temperature A low temperature B, when the temperature reaches or exceeds the A time, B, the warning is activated, the alarm is issued.

III.Exceptions

The anomalies are divided into two categories: container anomalies and operation anomalies. Container anomalies are replenishment timeout, thermal discharge timeout, temperature sensor, level sensor failure, etc., and operation anomalies refer to the opening of the lid.

①Refill timeout, that is, in the maximum refill time does not complete the refill action there will be a warning prompt, prompting the automatic refill during the suspension and can not start.

② Thermal discharge timeout, the thermal discharge cycle does not complete the action within the set discharge time, i.e. warning.

③ Temperature sensor failure, vapor-phase liquid nitrogen cryogenic tank temperature sensors A, B, C is not connected to the control terminal, or the sensor is damaged, there will be a warning issued to remind the user to deal with.

④ Failure of the level sensor, again without access to the control terminal or damaged, will result in a warning occurring.

⑤ Open lid timeout warning, i.e., there is a warning if the lid of the vapor-phase liquid nitrogen container is opened for a period longer than the set value of the open lid alarm time.

These are vapor-phase liquid nitrogen cryogenic tank automatic monitoring system can provide the scope of early warning, warning time in addition to sound and light + SMS, in addition to the main interface of the screen also has a prompt to ensure that the management of the remote process can see the details!
