General Description

Cryo-con’s Model 12 and 14 are the most flexible and accurate temperature monitors currently available. These two- or four-channel instruments have a level of sophistication not found in other monitors. Virtually any cryogenic temperature sensor from any manufacturer can be selected by a single setting of the front panel. Additional custom or specially calibrated sensors require only a simple setup procedure. In addition to its high accuracy/performance and low noise design, unique features include: Constant-Voltage AC sensor excitation, Internal Data Logging, Ethernet Connectivity, a large easy to read display and extensive utility software.

Ethernet connectivity adds a new dimension of utility to these monitors. In both industrial and laboratory applications, Ethernet is more reliable and easier to use compared to other communication standards. Furthermore, it is essential to remote, distributed sensor or Local Area Network based systems.

The Model 14 has four independent and identical multi-purpose sensor inputs whereas the Model 12 has two. Each can be easily configured to support virtually any cryogenic temperature sensor.

The front panel consists of a large, bright Vacuum Fluorescent display and a 5-key keypad. Most features and functions can be accessed via this simple and intuitive menu driven interface. All eight temperature readings are displayed in a 2 x 4 matrix.

The Model 12/14 connects directly to any 10/100 Base-T Ethernet Local-Area-Network or directly to any PC. Simple connection to any existing Local Area Network allows stable, precise, cost-effective measurements in laboratory or industrial environments as well as in remote, distributed data acquisition systems.

Using the Ethernet HTTP protocol, the monitor’s embedded web server allows the instrument to be viewed and configured from any web browser.

Using the SMTP protocol, the monitor will send e-mail based on selected alarm conditions. E-mail is completely configured by using the web page interface.

The TCP/IP data port server brings fast Ethernet connectivity to all common data acquisition software programs including LabView™. TCP/IP protocol is used to implement a text based SCPI compatible command language.

Applications

Cryogen-Free systems:

Up to four input channels. Cryogen-Free systems often require more than two.
Especially useful in ultra-low temperature cryogen-free systems.

General purpose laboratory:

Four inputs support virtually every cryogenic temperature sensor offered by every manufacturer.
Ethernet connectivity for ease of remote control. Significant upgrade over IEEE-488 or RS-232 based systems. Native LabView™ support.
Temperature activated relays and an analog output can be used to control external equipment including power supplies and cryogenic valves.

Remote and Distributed Instrumentation

Ethernet cables can be over 300 meters long without repeaters. This facilitates separation of instruments over great distances and allows the user to move the instrumentation closer to the sensor.
Easily connected to wireless networks and may even be connected to the Internet.
Many instruments can be connected to a single local-area-network. Instrument configuration can be performed remotely using a standard web browser.

Superconducting Magnets:

Cryogen-Free magnet systems often require many inputs.
Constant-voltage AC sensor excitation reduces temperature measurement errors and extends the temperature range on sensors that are commonly used in magnetic fields.

Data Acquisition / Computer Control:

The Model 12/14's Ethernet interface allows the simple and inexpensive connection of many instruments to a Local Area Network. It is directly supported by all data acquisition software packages including LabView™. Cryo-con provides Application Program Interfaces (APIs) that easily connect programming languages to the Ethernet interface.
The monitors also feature a robust implementation of the IEEE-488.2 SCPI command language. This language was designed to facilitate computer controlled system development by providing a standard structure and syntax.
The remote command language is identical across the entire Cryo-con product line, therefore ensuring your system software will not become obsolete. Software portability is significantly improved.

Industrial Control Systems:

The Model 12/14 will interface directly to a Programmable Logic Controller in order to control an industrial process. These are commonly used in low temperature refrigerators, cryogen generators etc.
Large scale control systems are best supported by the Ethernet interface which is used in the implementation of most industrial distributed instrumentation systems.
