Liquid Nitrogen Level Monitor/Controller
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.
