The Sycon Liquid Level Monitor/Controller is a capacitive level measurement and control instrument for use with non-flammable liquids such as liquid Nitrogen. Features include programmable setpoints, and I/O. A wide range of sensor lengths can be used. The gauge can connect to a PC via an RS-232/485 connection, and a LabVIEW application is available.
The SLL-N2 works with a capacitive sensor (probe). The probe active length and overall length can be sized to suit your application. Click here for details.

Cryo LN2 Probe
The capacitive sensor (probe) is made of stainless steel. Outside diameter is 0.375". The active length (sensing range) and overall length can be specified to suit your application.
The probe is typically installed in a dewar through a ferrule-type fitting to provide a secure, pressure-tight seal.
