Lakeshore drc-93CA cryo temperature controller
LakeShore DRC-93CA Cryo Temperature Controller
Temperature Stabilization to +/- 0.001K (details in pdf)
Read User's Manual for specifications, applications, etc.
DRC-93CA combines microprosessor convenience with true analog control. The DRC-93CA compares actual sensor voltage or signal with an analog voltage created by the unit which corresponds to the user's desired temperature or setpoint. It then uses proportional, deriviative, and integral control circuitry to eliminate temperature differences between the actual and desired temperatures. It provides heat with up to 1 amp of current into a 50 ohm resistive heater (when needed) to counter the cooling power of cryogenic systems.
3 term (PIC) real-time analog control
Internal programming with up to 99 steps for temperature profiling (ranp and soak)
Two five-digit sensor displays
Supports cards for Silicon diodes, GaAIAs diodes, platinum & rhodium-iron RTDs, germanium, carbon-glass and carbon-composite resistors, thermistors, capacitance sensors and thermocouples.
Individual sensor calibrations curve entry from front panel. UP to 25 curves
Now, our very own "fine print:"
