Description
The liquid nitrogen level monitor for LN2 tank indicates whether or not the tip of the probe is submerged in liquid nitrogen.
This is a binary low-level detector at the chosen probe position. It does not measure nitrogen volume or continuous liquid depth. See the ATEK WiFi LN2 level monitor for the product details.
Installation
The probe is attached to the end of a malleable stainless steel rod which allows the depth of the required nitrogen level to be easily adjusted.
Operation
The monitor records and transmits sensor readings to the ATEK platform. When the probe is no longer in nitrogen, a notification is sent via the ATEK platform to warn you that it is time to fill the nitrogen tank.
The sensor value displays:
-
0 when the probe is submerged (Normal)
-
1 when the probe is no longer in the liquid (Alert)
Why monitor the LN2 level?
As liquid nitrogen evaporates, it absorbs heat from its surroundings. Temperature alone does not show whether the liquid remains above the chosen probe position.
Once liquid nitrogen has evaporated, tank temperatures can rise. A refill warning at the chosen probe position complements temperature monitoring; the time available to respond depends on the tank, probe placement, and refill procedure.
ATEK’s LN2 probe records whether its tip is submerged or exposed, helping staff identify when the liquid falls below the chosen refill point. Use a separate suitable sensor to monitor temperature.
