animal temperature Controller ATC2000 is a low noise heating system for maintaining animal body temperature during experimental procedures. The DC heater is extremely quiet in terms of electromagnetic radiation. This is essential in electrophysiological recordings which are very sensitive to electromagnetic interference. The controller uses proportional, integral, and derivative (PID) technology in adjusting the DC voltage output. Compared with switched on/off type controllers, PID controllers provide a much more precise and stable control of temperature. The PID approach is also more immune to the variation of the experimental conditions such as change in animal size and unexpected disturbances. The controller has three temperature sensing inputs. ● The resistive temperature device (RTD) Probe input can be used to monitor an RTD rectal probe to control the animal temperature or to monitor ambient temperature, induction chamber temperature or any other temperature. When using a thermocouple probe, the thermocouple (TC) probe input can be used just like the RTD input. (A T type thermocouple must be used.) AN I MAL S U RGERY & S U PPORT l PID control for maximum temperature stability l Low Noise DC Heater l Three temperature sensor inputs l Automatic shutdown if the plate reaches 45°C ● The heater plate also has an internal temperature sensor. The ATC2000 monitors this sensor to prevent the localized hot spots under animal. Normal mode uses the configured sensor (RTD or TC) or the plate sensor to drive the control loop. Adaptive mode uses the temperature of the heated plate and the temperature of the subject to control. This approach is less prone to overshoot, but somewhat slower the normal mode, depending on the sampling rate used. ● Shutdown is a fail safe mode used if the plate temperature ever exceeds 45°C. The controller has three operational modes: ● The ATC2000 is tuned at the factory. However, the PID parameters may also be set manually. The temperature resolution of the controller is 0.1°C. The rectal temperature probe has a 6-ft ultra-flexible, shielded cable and an RTD sensor. The metal heating plates (available separately) have built-in temperature sensors. Compatible with stereotaxic systems, the rigid, flat surface fits under the U-frame. Plates are washable with water and detergent. ● ● atC2000 SPeCiFiCatiOnS TEMPERATURE RANGE . . . . . . . . . . .up to 45°C RESOLUTION . . . . . . . . . . . . . . . . . . .0.1°C ACCURACY . . . . . . . . . . . . . . . . . . . . .± 0.3°C RAT SENSOR . . . . . . . . . . . . . . . . . . . .RTD, OD 2.0mm tube with 3.5mm ball head (Optional mouse sensor is available) MAxIMUM DC OUTPUT . . . . . . . . . .10V, 3A An optional silicone pad (WPI #503573) is composed of a thermally conductive rubber material that is used to enhance the heat transfer to the animal.
