Expansion Thermometer
FISCHER
MESS- UND REGELTECHNIK
Type TA
Application
The expansion thermometer TA is used for indicating, monitoring and controlling.
It is used in ail industries where tempͩrature and temprature diffrences shall be registered.
Sp驩cial fields of application:
 Processing
Օ Environmental technology
 Heating and ventilating technics Climatology
Օ Foodstuff technology
Main features
The expansion thermometer disposes of a very rugged and vibration rsistant measuring System due to a con魭struction without motion work.
Further advantages are:
 High accuracy (class 1,0%)
Օ Very short reaction time
 Mechanical working
Օ Ambient temprature compensation and z魩ro point adjustment are standard
 Suitable for equipment of contact devices
Օ GL-test certificated
 Suitable in combination with R100 measuring resistor

Opration
Temprature changes at the pointer of the thermometer cause an expansion of the liquid which is enclosed in the pointer under supply of pressure. A conical spring will be deformed by the repressed expansion liquid and opens itself round the centre axle. The caused turning of the centre axle effects directly the pointer deflection. Pointer deflection 270 degrees.
