Hi all,

I need to detect the current used by a washing machine powered with a 230 V, and after trying a type of sensor with no results I would use one of these current transducers:

http://docs-europe.electrocomponents.com/webdocs/008f/0900766b8008f208.pdfIn detail, an AS-100 or AS-104 but looking datasheet or on the net I only found this site:

http://dcc-mueller.de/wire4dcc/sensor_e.htmBut I do not know if the circuit in Figure 4 can be used directly or whether it should be placed downstream of the circuit in Figure 1 or 2.

Attempting to calculate the shunt resistor for the sensor AS-104 according to the datasheet:

VMS = Rt x Is x (1/2F)

Rt (Ohms) = Recommended terminating reisstance

Is (A) = Secondary Current

F (Hz) = Frequency

in the table shows a value of 1500 for the VMS component AS-104, and a value of Is 30mA then the calculations that I made I put a 200 ohm resistor but I'm not sure I understood correctly the Datasheet:

1500 = Rt x 0.3 x (1/2 * 50)

Rt = 1500 / 0.3 x 25 = 1500 / 7.5 = 200

I thank in advance those who will help me

Hello
