Input range -200...+700°C
High accuracy ±0.05 % of span
Leadwire compensation up to 100 ohms
Linearization
Small case 22.5 mm
Mounting on DIN-rail

Our model 620S temperature transmitter is designed to
meet the most exacting temperature measuring requirements. Extreme accuracy is obtained by linearizing the
measurement signal with an accuracy of 0.05 % to the
temperature. Thus one transmitter can now replace
several of narrower range without reducing accuracy.
Leadwire resistance automatic compensation up to 50

ohms makes possible long transfer distances with smallcrossarea signel cables. Range can easily be varied by
changing the range resistors located under the front plate.
Normally transmitters are delivered calibrated according
to customer range requirements.
