Characteristics of the most important

resistance temperature sensors

These relays are used to measure temperatures

in solid, liquid and gaseous mediums. They

monitor temperatures to evaluate whether they

lie within a specific operating range (window

function). Our 3RS10 40 and 3RS11 40 relays

are in compliance with DIN 3440 as temperature

monitor; the 3RS10 42 and 3RS11 42 relays can

be used, in accordance with DIN 3440, as tem-

perature limiting devices. These represent a

good alternative to temperature controllers in

the low-end sector.
