Warning limiting resistances CDF-01 AU

Signaling limiting resistances CDF - 01 AU (hereinafter - signaling) are designed to provide information on the output resistance value of the resistive sensor installed guaranteed range (band).

Signaling devices are 3NK safety class according to NP 306.2.141.
The degree of protection IP 30 signaling in accordance with GOST 14254.
Working conditions for the application signaling:
- Ambient temperature 1 to 50 ° C;
- relative humidity 80% at 35 ° C;
- Atmospheric pressure from 84 to 106.7 kPa.
Warning has the following characteristic impedance conversion resistive sensor:
- Zone I: d 0 ≤ R ≤ R1max;
- intermediate zone: R1max ≤ R e ≤ RIImin;
- Zone II: RIImin ≤ R e ≤ ∞,
wherein R d - the resistance value of the resistive sensor;
R1max, RIImin - maximum and minimum values of the resistance zones guaranteed signaling according to Table
