Description: The Voltage Sensor measures the differential voltage between the input terminals and outputs the difference proportionally. The maximum differential voltage that can be measured accurately is ±30V. This sensor comes with a 60cm sensor cable.
The Voltage Sensor measures the differential voltage between the input terminals and outputs the difference proportionally. The maximum differential voltage that can be measured accurately is +/-30V. When the positive and negative inputs are equal, the analog output value is 2.5V. When the positive input is 30V greater than the negative input, the analog output is 4.5V and when the positive input is 30V less than the negative input, the analog output is 0.5V.
Since the 1135 Voltage Sensor can measure a differential voltage, the common mode rejection (CMR) is an important specification. CMR refers to the amount of voltage that both input terminals of an differential amplifier can be offset without affecting the output gain. For example, if the positive terminal sees a voltage of 7V and the negative terminal sees a voltage of 5V, then the CMR would be 5V and would output a value of 2V at unity gain. For the 1135 Voltage Sensor, it is able to measure the differential voltage of ±10V with a CMR of 40V while keeping the accuracy within 2%.
