Magnetic Reed Sensor

Hi all,

 

I want to use a Magnetic Reed Sensor, OMAL RV21, to a DAQ sensor.

Can someone recommend me a module to work with it? and can I use the NI-9205?

 

Tnx!

Hello Nitsan,

 

From what I was able to get about this sensor, maximum output current is 400 mA. NI 9205 is a good option for this measurement: however, you should include a shunt resistor at its output since this is a Voltage measurement module so you need to convert from mA (sensor output) to Volts (max 10 V). There are some NI modules can be used for current measurement, for example the 9227 is an option that can handle up to 5A rms.

 

Take a look at the following article might be useful for your application:

Have a great day!
