Model LM-510 Liquid Cryogen Monitor
Available now is a Helium Recondenser Controller Option!
The LM-510 can be configured with a Helium Recondenser Controller installed in Channel 2. It is designed to monitor pressure in a cryostat containing liquid helium and helium vapor that is equipped with helium reliquifier, and to add heat to the system as needed to maintain an optimal pressure for recondensing. Also, when properly configured, it prevents system contamination by maintaining positive pressure in the cryostat.

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:
- 240 x 400 TFT LCD display
The 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 X 2.50″ height X 7.00″ depth (184mm X 64mm X 178mm)
The LM-510 also includes the most popular features of the LM-500:
- The Single Channel Unit can be Configured to Monitor Liquid Helium or Liquid Nitrogen Levels
Choose configuration at time of order. - Optional Dual Channel Configuration can 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
