Techne FB08 Fluidized bath

The FB08 Fluidized bath offers excellent temperature stability and uniformity making it a good choice for temperature sensor comparison calibration work and shape setting of metals including Nitinol and platinum for Medical device manufacturing. With the optional probe holder which acts as an isothermal block, stabilities of better than +/-0.008ºC in dead-bed mode can be realized. Combine the FB08 with one of our Platinum resistance thermometer probes and indicator for a high performance temperature system. Here are some of the benefits of the FB08 Fluidized bath:

	The Fluidized bath of choice for critical processes requiring the highest stability and uniformity at temperatures up to 700ºC/1292ºF.
	Fluidized bath action is non-abrasive to any devices or parts put into the bath including those highly polished.
	Much more efficient than ovens (all heat is lost when opening the door) and salt baths. Fast recovery time after the bath is quenched.
	Much Safer than volatile salt baths
	Short term (15 minutes) stability and uniformity typically better than +/-0.2ºC

sensors and systems

Description: A rectangular bench standing unit, the controls for temperature and fluidizing air flow are mounted on a recessed panel on the front, together with on-off switches for the power supply and the dust extractor and indicators for various functions. Insulated and vented the outer case is safe to touch even at the maximum operating temperature. When Fluidized, the media is heated by four immersion heaters close to the container wall with the control thermocouple between the heaters. The internal components are protected by an air cutout switch that disables heat in the event the fluidizing air is lost. A clean/dry inert gas from an external source passes through two filters and regulators, to reduce the pressure for the cyclone extraction system and fluidization. Fluidizing air passes through a flow meter and then to the plenum chamber from which it is distributed evenly around the inner container. Dust extraction is by means of ambient air drawn from around the probe holder/plate and then through a cyclone to the exhaust filter. Alumina dust removed from the opening of the bath is deposited into the front mounted collection jar where it can be removed and dumped back into the bath.
Operation: Setting of the fluidizing air is by means of a combined control valve and flow meter. (Note: air adjustment is automatic with the FB08C) Fluidizing air requirements are inverse of the bath temperature. i.e- lower bath temperatures require more air for proper fluidization. The bath temperature is set by means of a front panel mounted PID controller. Sensors for calibration should be suspended as close as possible to the center of the bath. When calibrating sensors the probe holder is recommended as it is custom built with the dimensions of the sensors you will be calibrating.
Dead-bed method A major feature of the FB08 series is calibration using the Dead-bed method. During Dead-bed the power is shut off and 30 seconds later the fluidizing and extraction air are turned off. This causes the alumina to collapse around your work and provides a dense, high thermal insulation environment. For a period of three to ten minutes thermal equilibrium occurs and stability of better than ±0.008°C is observed.
