LakeShore DRC-91 CA Temperature controller
The DRC-91 CA Temperature Controller combines microprocessor based convenience with true analog control. The controller features:
- Three Term (PID) Real-Time Analog Control
- Two sensor input card slots
- Interchangeable input cards for: silicon diodes, GaAIAs diodes, platinum and rhodium-iron RTDs, germanium, carbon-glass and carbon composite resistors, thermistors, capacitance sensors and thermocouples.
- IEEE-488 interface
- Precision options which improve sensor display accuracy to between 1 and WOrnK, depending on sensor type and temperature range selection.
- Optional scanner which adds four sensor inputs expanding usage to six temperature sensors.
- Optional analog output
- Optional RS-232C card
Sensors
The DRC-91 CA is one of the most versatile instruments of its kind on the market. You can change sensor types by simply changing sensor cards or their configuration. Refer to LakeShore's Temperature Sensor Guide for sensor details.
Precision Options
For best precision, individual sensors should be used with the 8001 Precision Calibration Option. This option programs the instrument with calibration data for an individual sensor. The algorithm within the instrument interpolates between data points to an accuracy which exceeds 25mK over the entire temperature range of the Precision Option. Therefore, the overall system error, and that of the calibration itself, is reduced to a minimum. LakeShore calibrations are typically better than 20m K below 28K for diode sensors. See the LakeShore Low Temperature Calibration Service Brochure or Temperature Sensor Guide for additional discussion of calibration accuracy.
There are three types of Precision Options available for the DRC-91 CA
