Description
The DC Temperature Control System is a feedback based system for monitoring and maintaining subject or bath liquid temperature that also features:
25° – 45°C Heating Range, 40 Watt capacity
Proportional DC voltage does not generate electrical noise, no switching transient
Thermistor probes and heating elements available for all lab applications
Analog output of heater output for chart recording or other biological recording devices
Compatible with other probes (ex. YSI 400) through factory modification
Desktop or rack mountable
The DC Temperature Regulation Systems are designed to maintain a constant temperature of a subject or liquid without introduction of electrical interference. The proportional DC power supply slowly varies its output to the heating element based on the resistance of the monitoring thermistor. Electrical noise and switching transients common in AC-based devices is eliminated.
The DC Temperature Controller (40-90-8D) is powered through an internal power supply (country specific line cord ordered separately). It has an easy-to-read three digit LED display on the front panel indicating the subject or liquid temperature in tenths of a degree Celsius. Failing thermistors or similar electrically « open » situations are indicated by a red LED on the front panel labeled « OPEN »
A junction box is provided with the Controller, which connects to the module via a 2.5m shielded cable (extension cable available); thermistors and heating elements plug into this box.
The 40-90-5D-02 Rectal Thermistor Probe is small enough (.062″/1.6mm diameter) to maintain the body temperature of a range of mammals (mouse, rat, cat etc.). Heating pads (40-90-2-XX) are available in sizes suitable for any application.
The 40-90-3 Liquid Immersion Heating Rod and 40-90-6 Liquid Thermistor Insert can heat up to 1L of liquid and maintain a constant temperature to serve as a water bath or warmed perfusate.
FHC thermistors utilize 5000Ohm resistance. The DC Temperature Controller can be factory configured for 2252Ohm thermistors, e.g. YSI 400 series, and factory-modified for other heating elements (contact FHC Technical Support for more information).
An analog output provides a voltage related to the measured temperature (100mV/°C) for use with biofeedback recording systems. (ex. Chart recorders etc.)
The DC Temperature Controller contains an internal power supply that can be user-configured for 50 or 60Hz. Country specific line cords are specified separately. The module is compact and can be placed as a stand-alone unit on a desktop, or mounted in a standard 19″ instrument rack with our SAF rack frame.
