Model LM-510 Liquid Cryogen Monitor

Name: Model LM-510 Liquid Cryogen Monitor
Brand: Cryomagnetics, Inc.
SKU: LM-510

Compact, easy to use and configurable for use with a variety of sensor designs, the Cryomagnetics Model LM-510 series of Liquid Cryogen Level Monitors sets the standard for LHe and LN2 cryogen level measurement and control.

Paired with the optional Line Voltage Controller allows an affordable solution for LN2 autofill and automation.

The Model LM-510 features a large 240 × 400 TFT LCD display, a full numeric keypad with directional arrows, Ethernet and USB computer connectivity standard, 4-20mA and 0-10V analog outputs per channel, and web browser configuration.

The LM-510 also includes configurable single- or dual-channel operation for liquid helium or liquid nitrogen sensors, separate alarm and refill setpoints per channel, sample and hold operation, sensor burnout protection, de-ice cycle for helium level sensors, and level indication in centimeters, inches, or percent.

240 × 400 TFT LCD display — Large viewing angle and high contrast multi-color display makes it easy to see liquid cryogen levels and status of alarms/refill cycle.
Full numeric keypad with directional arrows — Unit setup is easier than ever with the expanded keyboard.
Ethernet and USB computer connectivity standard — IEEE-488.2 computer interface is available as an option.
4-20mA and 0-10V analog output — Each channel has both 4-20mA and 0-10V analog outputs as a standard feature.
Web browser utility — Latest firmware updates can be easily installed. Liquid levels can be monitored and resampled.
Universal power input — 100-240 Vac, 50-60Hz.
Compact dimensions — 7.25″ wide × 2.50″ height × 7.00″ depth (184mm × 64mm × 178mm).
Configurable single channel — Monitor liquid helium or liquid nitrogen levels. Choose configuration at time of order.
Optional dual channel configuration — Simultaneously monitor two liquid helium level sensors, two liquid nitrogen level sensors, or one of each. Specify at time of order.
Separate alarm and refill setpoints for each channel.
Sample and hold operation, burnout protection, and de-ice cycle for liquid helium level sensors.
Level indication in centimeters, inches, or percent.
Free LabVIEW® drivers.

Option 2: RS-232 Interface — Must pick IEEE-488.2 or RS-232; cannot have both.
Option 3: Rack Mount Panel
Option 4: Line Voltage Controller Output — Used to help automate liquid nitrogen refills.

An optional Helium Recondenser Controller can be installed in Channel 2 to monitor pressure in a cryostat containing liquid helium and helium vapor. The controller maintains optimal conditions for recondensing and prevents contamination through positive pressure maintenance.

This option is installed as a factory configuration and is available in combination with any single-channel LHe measurement channel — see the Model LM-510-13 configuration example.
