Multiple temperature sensing inputs

The Animal Temperature 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. 

Operational modes

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.

Required accessories

The ATC2000 Animal Temperature Controller 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 of the warming pads fits under the U-frame. Our homeothermic warming pads are washable with water and detergent.

A heating plate and a probe are required for use with this unit. Please see the Accessories tab.

This introduction video shows all the highlights of the ATC2000 animal temperature controller ( 3 minutes).

The ATC2000 Animal Temperature Controller 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 to provide precise and stable control of a subject's temperature. 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. Our unique adaptive mode technology automatically senses and adjusts the PID values based on the size of the animal.
