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. Simply place the silicone pad on the ATC2000 warming plate and
place the animal on silicone pad.
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.)
The heater plate also has an internal
temperature sensor. The ATC2000
monitors this sensor to prevent the
localized hot spots under animal.
The controller has three operational modes:
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 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.
