STRUCTURE <\/strong>OF THE RESISTANCE THERMOMETER
\n<\/strong><\/span><\/h2><\/div><\/div>
<\/div>\n

Resistance thermometers are manufactured and used today in a countless variety of designs. <\/span>The construction of a resistance thermometer is basically characterized by a measuring resistor, a corresponding housing and the required connection possibility.<\/b> The DIN 43772 standard defines only a very small number of designs, in which the components and dimensions are specified. <\/span>The standardized resistance thermometers always consist of a connection head, a protection tube and an exchangeable measuring insert and can be assembled in a modular way.<\/b><\/p>\n<\/div>

MODE OF OPERATION RESISTANCE THERMOMETER <\/strong>PT100<\/span><\/h2><\/div><\/div>

The measuring resistor is connected to a constant measuring current. The resistor generates a voltage drop which is measured. This voltage drop can be derived directly from Ohm’s law:<\/span><\/p>\n

U = R – I <\/b> U = voltage in V, R = resistance in \u03a9, I = current in A<\/b><\/p>\n

The measuring voltage must be transmitted as unaltered as possible to the place of evaluation or display. Especially due to the transmission in 2-wire circuit, the additional line resistance leads to an increase of the total resistance and thus inevitably to measurement errors. <\/span>To prevent the measuring resistor from heating up due to the measuring current, it should be selected as small as possible.<\/b> It can be assumed that a measuring current of \u2264 1 mA causes negligible self-heating in the measuring resistor.<\/span><\/p>\n<\/div><\/div><\/div><\/div><\/div>

Resistance thermometers are based on the use of platinum resistors (e.g. Pt100, Pt1000) . They provide the highest possible accuracy. <\/span>We manufacture screw-in, immersion, insertion and surface probes with application specific probe tips. For the special usage in laboratory environments we manufacture different resistance thermometers in glass design – in part also with ground glass joints. <\/b>Different head resistance thermometers with measuring inserts and protective tubes as well as special versions also form part of our range.<\/span><\/span><\/p>\n<\/div>
