Cryogen level metering card for Mercury instruments ITC and IPS units. Customisation is possible through the addition of plug and play expansion cards. The controller features 9 expansion slots (8 multi-function slots and a dedicated GPIB slot) which can be used to extend its capability.
Cryogen level metering card for MercuryiTC and MercuryiPS master units:
• Plug and go card for Oxford Instruments Mercury Instrumentation
• Supports duel cryogen level metering of Nitrogen and Helium
• Connecting cables (E2-822 or E2-823) NOT included Each card supports a Helium Level input and a Nitrogen Level input
• Helium Level specifications ◦Excitation current settings: 20 mA to 280 mA in 20 mA steps ◦Excitation current accuracy: ±5% ◦Excitation voltage: 40 V maximum ◦Probe resistance: 0 to 300 ohms ◦Probe resistance accuracy: ±0.2% ◦Probe resistance stability: ±0.1% ◦A/D Resolution: 24-bit ◦Reading rate: 1 sample every 10s or 1 sample every 30 minutes. ◦Isolation: All sensors independently isolated
