General Description

The Model 24 is a four-input, dual control loop cryogenic temperature controller designed for general purpose laboratory and industrial use.

Each input is independent and capable of temperature measurement to <500mK with an appropriate temperature sensor.

The Model 24 supports virtually any cryogenic temperature sensor produced by any manufacturer.

The dual-output control loop circuits features a primary 50W heater and an independent secondary heater of 10W.

For superior operation in cryocooler based applications, the Model 24 implements a synchronous filter that eliminates the thermal noise signature of the cooler.

Cryo-con’s Model 24 incorporates Ethernet connectivity which adds a new dimension of flexibility to industrial and laboratory applications.

Applications

Cryogen-Free systems:

Proprietary cryocooler thermal signature removal offers the best control stability in the industry for cryocooler based systems.
Four input channels. Cryogen-Free systems often require more than two.

General purpose laboratory:

Four inputs support virtually every cryogenic temperature sensor offered by every manufacturer. Two thermocouple inputs are optional.
Stepless Constant-Voltage excitation offers the widest possible temperature range for a given sensor.
Dual control loops. Digital Signal Processing techniques extend control loop resolution to provide the best control stability and widest range in the industry.
Ethernet connectivity for ease of remote control. Significant upgrade over IEEE-488 or RS-232 based systems. Native LabView™ support.
Robust cryostat protection controls.
Complete instrument configurations may be saved and instantly restored.

Superconducting Magnets:

Constant-voltage sensor excitation extends the high and low temperature range of sensors normally used in high magnetic fields.
Cryogen-Free magnet systems often require more than two inputs.

Data Acquisition / Computer control:

Ethernet interface in addition to IEEE-488 and RS-232. Ethernet 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™.
Robust implementation of the IEEE-488.2 SCPI command language facilitates system software development.
Remote command language is identical across the entire product line, therefore ensuring your system software will not become obsolete.
