The Cryo-Con 34 is a cryogenic temperature controller engineered for precise thermal management in research and industrial cryogenic environments. It delivers advanced PID control with configurable setpoint zones, multiple sensor compatibility, and remote command capability across standard laboratory interfaces. The system supports manual, ramp, and step control modes with NIST-traceable calibration.
## Technical Specifications
**Power Input**
• Single-phase AC, 50–60 Hz
• Selectable line voltage: 100, 120, 220, or 240 VAC (rear-panel selector)
• Tolerance: +10% to −5% for specified accuracy; −10% reduces full-scale heater output on highest range
**Control Architecture**
• Four user-programmable PID tables
• Up to 16 setpoint zones per table
• Each zone entry: setpoint, P, I, D values, and full-scale heater range
• Interpolated PID coefficients and heater range derived from setpoint location
• Manual mode: direct loop output as percentage of full-scale
• Ramp and step control modes supported
**Sensor Support**
• Silicon diodes and Platinum RTDs (wide variety of cryogenic sensor types)
• Pre-installed calibration curves for most common sensors
**Communication Interfaces**
• Ethernet and RS-232 standard
• GPIB (24-wire protocol) and USB available as optional
• SCPI-compliant command language
• Remote I/O debug lines for command/response monitoring
• LabView drivers available for all interfaces
**Safety & Calibration**
• Protective grounding to minimize electrical shock hazard
• Sealed enclosure—not user-serviceable
• Calibration traceability to NIST
## Key Features
• Flexible PID table architecture enables zone-based control across wide temperature ranges
• Interpolated control parameters eliminate step transitions between setpoint zones
• Multiple remote interface options support laboratory automation workflows
• Pre-calibrated sensor support reduces deployment time
## Typical Applications
Research laboratories requiring stable cryogenic temperature control; dilution refrigerator systems; materials science and physics experiments; industrial process control in cryogenic environments.
## Compatibility & Integration
The controller integrates with standard laboratory networks via Ethernet or RS-232. GPIB and USB connectivity available for legacy or specialized instrument configurations. SCPI command compliance ensures compatibility with instrument control software and LabView-based measurement systems.
