The TCAT-2 family of general purpose PID Auto-tuning Controllers provides
accurate temperature control in a variety of laboratory applications. Combined
with a heat lamp or heating pad, the TCAT-2 may be used to maintain the body
temperature of anesthetized animals during surgery or stereotaxic procedures.
Small animal cages are easily warmed with a heat lamp. The TCAT-2 may also be
used in cooling applications, such as to control independent perfusate cooling
systems. Realizing that laboratory applications are diverse, several versions of
the TCAT Controller are provided. The model specified depends on whether a
laboratory has a general or specific need for the controller:
This version controls only AC powered heating or cooling devices such as a heat
lamp. It is the least costly.
This model provides a low-voltage DC output for electrically sensitive
applications where AC frequencies might interfere with other monitoring devices.
It comes standard with a built in DC power supply designed to operate with our
HP-1M Heating Plate for small rodents. The TCAT-2LV utilizes a dual set point
control circuit to prevent a heating element from overshooting the control point
due to thermal lag in the control system. This is an important feature in
preventing burns due to incorrect control settings or faulty feedback sensor. On
a custom basis, we can provide a variety of DC power supplies Depending on the
load power requirements.
This is a combination version which includes both an AC outlet for controlling
primarily resistance loads such as heat lamps, AC powered warming blankets and a
low-voltage, low-noise" DC output for heating pads. This version allows you to
control a variety of different loads.
All TCAT-2 versions may be used with any of our extensive line of accurate Type
T thermocouple probes, which act as the temperature feedback sensor. Most
commonly used are the RET series of animal rectal probes, but the IT series of
implantable flexible probes and MT series of needle probes may also be used
depending on the specific application. All instruments are designed to operate
on a 110V or 230V AC supply. The unit comes in a durable baked enamel painted
aluminum housing. Adjustable front feet allow the user to raise the front of
controller to provide a more convenient viewing angle. A heat/cool switch is
provided when using the controller with cooling devices such as small
refrigeration compressors or thermoelectric stages. In the cooling mode it
inverts the control function and shuts off the load when feedback sensor
temperature falls below the set point. A small lamp on the front of the control
unit indicates when power is being applied to the load. The TCAT-2 is simple to
set-up; connect the feedback sensor to the animal and to the back of the
controller, connect the heating pad, blanket, lamp or cooling device to the
appropriate outlet on the rear of the controller. Adjust the set temperature as
required (lower green display) according to the instruction label on top of the
instrument. The set temperature is stored in memory after the unit is switched
