Description
Monnit wireless voltage meters are capable of measuring the voltage off another device, battery, or sensor. This sensor is capable of measuring voltage up to 500 VAC by connecting the leads on the sensor to the positive and ground terminals of the device being measured.
Examples of interfacing devices include, but are not limited to: Strain Gauge, Pressure Transducer, RTD, Thermistor, or Thermocouple, Piezo Electric sensors, Photoresistor, Industrial Accelerometer, any kind of variable resistor, any kind of sensor that outputs a voltage, etc. If the device being measured is passive, the user must supply their own excitation voltage, as the Monnit sensor is a “voltage observer”.

WARNING: Use caution when interfacing to the Monnit Wireless Voltage Meter. Negative voltages, any kind of AC Voltages exceeding 600V WILL DAMAGE the electronics of the Monnit Wireless Sensor. Monnit is not responsible for troubleshooting, replacing or reimbursing damages incurred by disregarding this warning.
Features
- Max sensor input voltage up to 600 volts (will return a max of 500 volts in software)
- Interfaces with devices and power supplies up to 500 VAC
* Actual range may vary depending on environment.
** Battery life is determined by sensor reporting frequency and other variables.
