How do you handle probe installation in tanks that are currently in active use and cannot be emptied?

Probes are designed for insertion through standard tank ports without requiring tank drainage, and cable lengths are cut to specification so the sensing tip reaches the correct depth for the tank's fill level. Installation typically takes under 30 minutes per tank with no interruption to stored samples.

At –196°C, standard cable insulation becomes brittle — how are the probe cables protected?

Cables are specified in cryo-rated PTFE insulation that remains flexible down to –200°C, preventing cracking and short circuits that would produce false readings or complete sensor failure. All probe materials are selected for long-term stability in liquid nitrogen immersion environments.

Can the system distinguish between a genuine temperature rise and a momentary reading spike caused by adding liquid nitrogen?

Yes, alarm delay settings allow you to configure a hold-off window of one to several minutes so that the brief temperature perturbation during LN2 top-up does not generate a false alert. If the temperature does not return to range within the window, the alarm fires as a genuine deviation.
