4.3.4 Micro bath calibrator
Type
TCL-3M165E2
Micro bath
CAUTION! Risk of injury - Wear safety goggles!
Calibration liquid can be ejected when working with the micro bath calibrator.
Always wear safety goggles for the eyes when handling calibration liquids.
The micro bath is used for calibrating sensors with special shapes or dimensions. Direct
contact between the sensor and the calibration liquid ensures excellent heat transfer.
The calibration liquid is poured directly into the tank or into a tub insert (
p. 22).
The micro bath includes the transport cover, the work cover, the sensor cage, the magnetic
stirrer, the drain syringe, the magnetic lifter and as an accessory, the tub insert. The
individual components are described below.
Transport cover:
The transport cover serves for secure closing of the micro bath. It prevents spillage of the
calibration liquid during transport.
CAUTION! Safety valve!
The transport cover is equipped with a safety valve, which is activated
once the pressure reaches ~1.5 bar (~21.75 psi). This can result in hot
steam being released.
Always unscrew the transport cover before putting the micro bath into service, in
order to avoid excessive pressure.
Work cover:
The work cover fulfils various tasks during the operation.
•
It reduces the evaporation of the calibration liquid to a minimum.
•
It reduces the cooling on the surface of the calibration liquid.
•
It ensures stable positioning of the test specimens in the micro bath.
The work cover is screwed on to the micro bath and has five openings for
test specimens. The unused openings can be closed with suitable silicon
plugs.
Sensor cage and magnetic stirrer:
The sensor cage protects the magnetic stirrer. It prevents the sensors from
blocking the magnetic stirrer. The function of stirring is ensured by the
sensor cage.
The magnetic stirrer ensures a uniform temperature distribution in the
calibration liquid. The speed of the magnetic stirrer is set in Configuration
range (
§ 5.2) or in the window "Configure Function" (
speed").
IMPORTANT! Limited Life Part!
The magnetic stirrer is a limited life part.
Replace worn-out magnetic stirrers. (
