FB-08
The standard FB-08 o ers a wide operating range of 50 to 700°C (122-1292°F), PID temperature control and a built-in dust extraction and
collection system. Fluidizing air is manually controlled in the standard FB-08, whereby the FB-08C includes automatic  uidizing air control and
RS232 interface for remote user control via a PC. Both the FB-08 and FB-08C are shipped with a single probe plate, ring and one charge of
 uidizing media (alumina). The probe holder, available as an accessory, is used to enhance the thermal conditions (control stability and uniformity)
of the temperature zone within the bath. It is manufactured, by special order, to suit sensors under test.

Sensor calibration or precision heat treatment is simple and precise with the FB-08 series  uidized baths:
- Set the bath to the required temperature and air  ow level (on standard units).
- Suspend the sensor to be tested in the bath (using the probe plate supplied or basket) in the working area and allow the bath to stabilize.
- Calibration or heat treatment can now be carried out using either a certi cated standard (comparison method) or the readout from the FB-08 control unit
(direct method).
The FB-08C has been designed to allow calibration of thermal sensors with minimum supervision. Working in conjunction with a supervisory com-
puter, via an RS232 interface, programs are created by the operator, allowing for the control of set temperature, incremental temperature steps and
dwell times. The automatic  uidizing air control will adjust the air  ow rate to suit the set temperatures of the bath. Where an ultra stable
temperature condition is required, a “dead bed” state can be programmed into the system.
