The CTC100 Cryogenic Temperature Controller is configured to suit a wide range of research and industrial applications.
The system consists of four sensor inputs, two powered and four analog voltage outputs, and up to six feedback control loops.
Four general purpose analog and eight digital I/Os are available, along with autotuning functions for setting PID parameters automatically
The CTC100 offers four temperature inputs that can read RTDs, thermistors, and diodes. Each temperature input channel has its own 24-bit ADC with eleven input ranges, and is equipped with its own independent excitation current source.
Standard calibration curves for a variety of sensors are included, and custom calibration curves of up to 200 points each can be entered. Each sensor input has high and low level or rate-of-change alarms. Sensor inputs can be lowpass-filtered to reduce noise, and/or differenced with another channel.
Powered and Analog Voltage Outputs
The CTC100 has two heater outputs. Either heater output alone can deliver up to 100 W of power to a 25 Ω heater. When operated simultaneously, the two outputs can deliver a total of up to 150 W of power. In addition, four analog voltage I/O channels can be used to drive heaters with the help of an external amplifier.
Numeric and Graphical Display
The CTC100's color LCD display can show any combination of temperature measurements and heater outputs on graphs or numeric displays. Up to eight channels can be plotted either on a single graph with a common Y axis, or on separate graphs with independent Y axes. Touchscreen operation makes the instrument versatile and easy to use.
