Manual induSENSOR Serie EDS - Micro-Epsilon

4.4.4 Load Resistor, Maximum Operating TemperatureThe sensors are connected according to the pin assignment shown, see Fig. 18 et seq. (all series). Notice thedifferent criterias:--R L max= (U B- 10 V) / 20 mA--R L min= 82.5 * 1/V * U B- 1625 Ohm--T max= 150 °C - 3.3 °C/V * U B+ 0.04 °C/W * R LThe maximum load resistor R Lis limited by the operating voltage U B.(U - 10 V)R BL max =20 mAA small load resistor loads the sensor electronics more thermical. With a maximum operating temperature of85 °C (+185 °F) the minimum load resistor R Lpermitted is calculated as:82.5 * UR L min = B - 1625 OhmV(If the result is negative: R L= 0 Ω)With a preset load resistor the maximum operating temperature permitted is calculated as:3.3 * UT max= 150 °C - B +VR L= Load resistorU B= Operating voltageT max= Maximum operating temperature0.04 * R LOhm ; and T max≤ 85 °CinduSENSOR, EDSPage 32
