Cryogenic Temperature Monitors C-series- Brochure

Cryogenic Temperature Monitors C-seriesTwo to eight input channels with Ethernet connectivityLOT-QuantumDesign Europe. For your local contact click at: www.lot-qd.comE-mail: magnetometry@lot-qd.comThe Cryo-con C series monitors are the most compact and flexible cryogenic temperature monitors on the market. Virtually any cryogenic temperature sensor from any manufacturer can be selected by a single set-ting of the front panel. Additionally, custom or specially calibrated sensors require only a simple setup proce-dure. Unique features include: Low cost per channel, Power-over-Ethernet, internal data logging, ethernet connectivity, a large easy to read display and extensive applications software. n Two, Four or Eight multipurpose input channels sup-port Diode, Platinum RTD and most cryogenic NTC temperature sensors. Dual thermocouple inputs are optional. n Operation from 1.0K to over 1500K with an ap-propriate sensor. Constant-Voltage, AC excitation of resistive sensors minimizes errors and extends their useful temperature range. n Continuous data logging into internal non-volatile memory. n Two large, dry-contact relay outputs. n Flexible input power: Power-over-Ethernet or 7.5 –24V AC/DC. n Built-in web server. Temperature monitoring and instrument configuration can be performed using any web browser. n E-mail on a selected alarm condition. n Remote interfaces include 100/10 Ethernet and RS-232. USB 2.0 and IEEE-488.2 (GPIB) are optional. LabViewTM drivers available for all interfaces.Input optionsThe Model 18C has eight input channels, the 14C has four and the 12C has two. All inputs are identical and independent with each capable of supporting the same wide range of sensor types. Other than the input channel count, there are no differences in the C-series monitor line.Easy to useThe monitor’s front panel consists of a large, bright TFT-LCD display a 4-key keypad, an audio alarm and three status LEDs.Several display formats may be selected. Up to eight temperature readings may be displayed simultaneously or two channels with input names and temperature shown in a large easy to read font. Additional screens include temperature readings along with relay and alarm status information are also available. A single key press takes the screen to a menu tree where most features and functions of the instrument can be config-ured. The status of built-in alarms and relays is indi-cated by LEDs located below the display.Input flexibilitySilicon diode sensors are supported over their full temperature range by using 10uA constant-current DC excitation. Positive Temperature Coefficient (PTC) resis-tor sensors including Platinum and Rhodium-Iron RTDs use constant-current, AC excitation. Platinum RTD sen-sors have built-in DIN standard calibration curves that have been extended to 14K for cryogenic use. Lower temperature use is possible with custom calibrations.Auto-ranged, constant-voltage AC excitation is used to provide robust support for cryogenic Negative Tem-perature Coefficient (NTC) sensors including Ruthenium-oxide, Carbon-Glass, Cernox™, Carbon-Ceramic, Germanium and several others. Thermocouple sensors are supported by using an optional dual thermocouple module. This module plugs into any of the input channels. It is powered by the instrument to provide amplification, cold-junction com-pensation and connection to copper.Cryogenic Temperature Monitors C-seriesTwo to eight input channels with Ethernet connectivityLOT-QuantumDesign Europe.

The IEEE 802.3af Power-over-Ethernet (PoE) specification is also sup-ported, allowing the Model 18C to be powered by it’s local area network connection. Since PoE provides both instrument power and data over a single cable, remote data acquisition and high channel count systems can be simplified. PoE requires the use of a powered hub or power injector. Ethernet cables up to 300 meters may then be used.Data loggingData Logging is performed by continuously recording temperature and status to an internal circular memory buffer. Data is time stamped so that the actual time of an event can be determined. Non-volatile memory is used so that data will survive a power failure. The monitors will log up to 800 samples. Each sample includes readings for all input channels.Alarms and relaysTwo 10.0A dry-contact relay outputs are available that can be asserted based on temperature setpoints from user selected input channels. These relays are large enough to switch most cryogenic valves. The visual, remote and audible alarms are supported. Each may be programmed to assert or clear based on temperature setpoints. Alarms may be latched. These are asserted on an alarm condition and will remain asserted until cleared by the user.Remote controlStandard remote interfaces include 100/10 Ethernet and RS-232. An IEEE-488.2 GPIB interface is optional and may be field installed at any time. The option con-sists of an external module that is automatically config-ured by the monitor. A USB 2.0 serial port emulator op-tion is also available. Monitors connect directly to any 100/10 Ethernet Local-Area-Network (LAN). The TCP and UDP data port servers bring fast Ethernet connec-tivity to data acquisition software including LabViewTM. Using the SMTP protocol, the monitor will send e-mail based on selected alarm conditions. Using the Ethernet HTTP protocol, the monitor’s embedded web server allows the instrument to be viewed and configured from any web browser.Cryogenic Temperature Monitors C-seriesTwo to eight input channels with Ethernet connectivityLOT-QuantumDesign Europe.
