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 10 VDC 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 really just a “voltage observer”. Cannot be used for AC voltage measurement.
WARNING: Use caution when interfacing to the Monnit Wireless Voltage Meter. Negative voltages, any kind of AC Voltages, or DC Voltage exceeding 20V 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 20 volts DC (will return a max of 10 volts in software)
- Interfaces with other devices up to 10 volts DC
* Actual range may vary depending on environment.
** Battery life is determined by sensor reporting frequency and other variables.
