Model LM-510 Liquid Cryogen Monitor

Building on the highly successful Model LM-500 Liquid Cryogen Level Monitor, Cryomagnetics is pleased to introduce the next generation Model LM-510.

Building on the highly successful Model LM-500 Liquid Cryogen Level Monitor, Cryomagnetics is pleased to introduce the next generation Model LM-510. New features of the Model LM-510 include 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 the most popular features of the LM-500 — 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 1: IEEE-488.2 Interface — Must pick IEEE-488.2 or RS-232; cannot have both.

  • 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.
