The MercuryiTC is a versatile cryogenic environment controller. In its basic form it includes a single channel high-resolution (24 bit) temperature measurement circuit which supports all the standard cryogenic sensors (ruthenium oxide, cernox, silicon diodes, platinum, thermocouple and RhFe). With the constant voltage mode it enables reliable, accurate temperature measurement using negative temperature sensors (NTC) down to below 250 mK. The base unit enables PID loop configuration control of a single heater output up to 80W (40 V, 2 A).
The base unit incorporates a versatile touch screen display with signal widgets (18 widgets) that are user configurable to display any of the internal system signals. The unit is fully controllable by remote command via TCP/IP, USB, RS232 or optional GPIB. Any of the available system signals are also available by remote command.
The base unit is expandable with plug-and-play cards. There are 9 expansion slots, 8 multi-use and 1 dedicated for GPIB. The expansion slots allow the addition of 8 extra temperature sensor cards, or 3 temperature sensor cards coupled with 3 additional 80W heater cards to form a total of 4 independent PID loops. Or pressure sensors cards can be added which can be used to control cryogen flow via Auxiliary (Gas Control) cards.
Please note: The temperature sensor – heater PID loop algorithm also includes a feature to balance a cooling cryogen flow without the need of a pressure card. The MercuryiTC will also support the Cryogen level meter card for monitoring Helium and Nitrogen cryogen levels
Interfaces: Ethernet, Serial, USB or optional GPIB
