Myself Sumanta Kumar Show, Research Scholar in the Dept. of Electrical And Electronics Engg. of NITK Surathkal. I am using voltage sensor (LV25-P) and current sensor (LA 55-P). The voltage sensor is having a conversion ratio of (2500:1000) and for current sensor it is (1:1000). But in actual circuit we need a conversion ratio of (1:1) for both the sensors.

Please suggest the external circuit which can be added with the Sensor ckts for achieving the desired conversion ratios. I will be waiting for your response.

Thanks in advance.
 

Hi,

Are you sure it makes sense to get 1:1 ratio? The sensor are especially made to lower voltage and current.

The voltage sensor has conversion rate of 2500:1000. Just use an amplifier with gain of 2.5.

The current sensor has 1:1000 ratio. Then use an amplifier with gain of 1000. (i really don´t think it makes sense)

What are the voltage and current levels that you plan on measuring?

For instance, if your current level to be measured is 500 amps, a transducer with a 1:1000 ratio will lower it to a much safer 500 milliamp. That is the reason for having transducers with lower ratios.
