Resistance thermometers approved to DIN 34 40

Transcription

1 Data Sheet Page 1/5 Resistance thermometers approved to DIN for indirect heating installations to DIN for temperatures up to 700 C as single, twin or triple resistance thermometer for operation in water, oil or air for approved control and limiter instruments The resistance themometers cited in this Data Sheet are suitable for approved temperature control and limitation equipment to DIN (see table on page 5/5). Resistance thermometers are preferably used for measuring temperatures in liquids and gases. Applications include HVAC and refrigeration, as well as heating installations, ovens furnaces and plant engineering. The terminal head Form B is suitable for ambient temperatures up to 100 C. Protection tubes in different materials protect the measuring insert from chemical influences and mechanical damage. The choice of the appropriate protection tube material depends on the conditions prevailing on site. The measuring insert is normally fitted with a Pt100 temperature sensor to EN , Class B in 2-wire circuit. Modifications to the versions described below require a fresh type approval. Please state sales no. as per price sheet when ordering!

This depends both on the nominal length NL and on the measured temperature. The table shows the error per 100mm fitting length EL for different measured temperatures. t/ C R/Ω t/k Resistance of a 0.5mm NiCr wire per 100 mm fitting length EL (2 lengths of wire).
