ULTRA Wireless Voltage Meters - 0-500 VAC/VDC - AA Battery Powered (900 MHz)
ULTRA 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/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 E2E sensor is really just a “voltage observer”.
ULTRA - Leading Enterprise Grade "Internet of Things" Solutions
ULTRA 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 ULTRA sensors to have better interference immunity from other wireless devices.
Superior power management provides ULTRA sensors with almost twice the battery life of E2E’s standard wireless sensors.
- Coin cell sensors typically last 3+ years.
- AA and Industrial sensors typically last up to 12+ years.
Integrated on-board data storage allows ULTRA 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 ULTRA products to be updated remotely if new fixes or features become available.
The standard version of this sensor is powered by two replaceable 1.5 V AA sized batteries (included with purchase). This sensor is also available with a line power option. The line powered version of this sensor has a barrel power connector allowing it to be powered by a standard 3.0 - 3.8 V power supply (Included with Line Power option upgrade). The line powered version also uses two standard 1.5 V AA batteries as backup for uninterrupted operation in the event of line power outage.
Power options must be selected at time of purchase, as the internal hardware of the sensor must be changed to support the selected power requirements.
WARNING: Use caution when interfacing to the E2E Wireless Voltage Meter. Negative voltages, any kind of AC Voltages, or DC Voltage exceeding 600V WILL DAMAGE the electronics of the E2E Wireless Sensor. E2E is not responsible for troubleshooting, replacing or reimbursing damages incurred by disregarding this warning.
- Interfaces with devices and power supplies up to 500 VAC/VDC
- Max sensor input voltage up to 600 volts (will return a max of 500 volts in software)
* Actual range may vary depending on environment.
** Battery life is determined by sensor reporting frequency and other variables.
