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”
ALTA Industrial Wireless Voltage Meters - 0-500 VAC/VDC with Solar Power
ALTA - Leading Enterprise Grade "Internet of Things" Solutions
ALTA sensors offer 3 to 4 times the range of standard sensor platforms, extending non-line-of-sight reach to an exceptional 1,200+ feet through walls (12-14 walls typical). Using Frequency-hopping Spread Spectrum (FHSS) also allows ALTA sensors to have better interference immunity from other wireless devices.
Superior power management provides ALTA sensors with almost twice the battery life of Monnit’s standard wireless sensors.
- Coin cell sensors typically last 3+ years.
- AA and Industrial sensors typically last up to 12+ years.
ALTA products employ Monnit's new Encrypt-RF® Security (256-bit Diffie Hellman key exchange and AES-128 CBC encryption for all sensor data messages), so security is maintained at all communication points from sensor to gateway, gateway to software, then back again.
Integrated on-board data storage allows ALTA sensors to store data messages if communication to a wireless gateway is disrupted (power outage, Internet outage, or out of range). Messages that can’t be delivered will be time-stamped and stored in memory (up to the last 512 messages) until communication with the gateway is restored, at which point the messages will all be transmitted.
Over-the-air updates allow ALTA products to be updated remotely if new fixes or features become available.
Monnit ALTA Industrial Sensors come in an IP65, NEMA 4X, CE rated, sealed, and weatherproof enclosure. They are powered by a single, replaceable, Industrial grade 3.6 V battery (included).
An optional solar powered version is also available. The solar powered version includes a Lithium Iron Phosphate rechargeable battery in conjunction with a solar power cell to keep the battery charged and at optimal capacity. If there is no light present at the solar cell, the battery alone could continue to power the sensor for up to 8-10 years.
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.
- 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.
