Wireless 200 VDC Voltage Meters

Remotely monitor device voltage

Monnit’s Wireless 0–200 VDC Voltage Meters monitor potential differences between two electrical points.

Easy deployment

Retrofit these sensors to legacy machinery, “dumb” devices, solar power units, or material handling equipment within 15 minutes. The sensors monitor the electrical status of assets at user-designated intervals. If this status deviates from a user-determined range during measurement, an alert is issued via text, email, or call.

Three sizes of battery-powered 200 VDC voltage meters are available for a broad array of installs: an ultra-compact CC model, an enterprise-ready AA model, and a weatherproof, industrial-grade device. Options include power source, on/off switches, and antenna styles.

Monnit’s US-made voltage meters are the easiest way to ensure battery-operated and low-power devices will be ready when you need them. Find your voltage metering solution below.

WARNING: Use caution when interfacing to the Monnit Wireless Voltage Meter. Negative voltages,AC Voltages, or DC Voltage exceeding 250V, WILL DAMAGE the electronics of the Monnit Wireless Sensor. Monnit is not responsible for troubleshooting, replacing or reimbursing damages incurred by disregarding this warning.

The power of knowing

Adding a Monnit Wireless Volt Meters to common industrial sensors uncovers power data that shapes operations—and the bottom line—by helping you ensure uptime.

Within 15 minutes, these sensors can be deployed and monitoring batteries, lower-powered machinery, and small electric motors with an accuracy to ± 3.0% full scale of the voltage range. If voltage deviates from user-set parameters, an alert is issued via text, email, or call. Designated personnel can step in and ensure continued processes or performance.

Spec the right-sized meter

These US-made voltage sensors are available in compact, enterprise-ready, and industrial-grade models. Options include solar power or on/off switches (based on model); if you have highly specialized machinery, consult Monnit Labs for custom sensor creation.

Ensure vital equipment is sufficiently energized and stay ahead of potential faults with one of the turnkey volt meters below.

WARNING: Use caution when interfacing to the Monnit Wireless Voltage Meter. Negative voltages, AC Voltages, or DC Voltage exceeding 20V WILL DAMAGE the electronics of the Monnit Wireless Sensor.

ALTA and ALTA XL IoT Gateways

Get Best-in-Class Cellular and Extended Connectivity

The ALTA^® IoT Gateways and ALTA XL^® IoT Gateways combine a 4G LTE CAT-M1/NB2 cellular engine and Ethernet platform (Enterprise only) with Monnit’s wireless access point network to aggregate and communicate data from Monnit ALTA^® Wireless Sensors.

A major part of the solution that won the 2024 IoT Product of the Year Award, the ALTA XL IoT Gateway also has a powerful wireless transceiver with up to 1-Watt transmission strength, an amplified receiver, and 4G LTE CAT-M1/NB2 cellular technology to backhaul ALTA Wireless Sensor data. The ALTA and ALTA XL IoT Gateways allow ALTA Wireless IoT Sensors to operate on the world’s leading cellular networks and stay connected to the Internet.

To meet the global demand for enterprise IoT deployment, the IoT Gateways communicate with the cloud-based iMonnit™ Monitoring Software via cellular transmission, making it ideal for remote locations or where the Internet isn’t available. The RJ-45 Ethernet jack (Enterprise only) allows local device configuration, diagnostics, and connectivity backup. The IoT Gateway is instrumental in sending sensor notifications via text, email, or call if user-defined conditions are met or exceeded.

  • The ALTA IoT Gateway communicates with battery-powered sensors up to one mile (line-of-sight) and 1,200 ft+ through 12+ walls (non-line-of-sight)
  • The ALTA XL IoT Gateway can receive and send data communications 2,000 ft+ through 18+ walls in commercial building environments.
• Bank-level security: Encrypt-RF® (Diffie-Hellman 256-bit Key Exchange and AES-128 CBC)
• Redundant power: AC main power with battery backup lasting up to 60 hours
• Superior scalability: Supports up to 100 ALTA Wireless Sensors
• Uninterrupted data collection: Onboard memory stores up to 32,000 sensor messages (Data stored during Internet outages is sent when connectivity is restored.)
• Broad compatibility: LTE CAT-M1/NB2 for global use in bands: 1, 2, 3, 4, 5, 8, 12, 13, 18, 19, 20, 25, 26, 27, 28, 66, 71, 85
• Future-proof software: Firmware over-the-air (FOTA) upgrades included
• Location Awareness: Comes with GPS data tracking capability and is available as an add-on service via an API.

The ALTA IoT Gateways and ALTA XL IoT Gateways are available in Enterprise and Industrial versions. Get more information about them below.

Wireless Pressure Meters

Always know supply line pressure.

Monnit’s battery-powered ALTA^® Wireless Pressure Meters—winners of the 2024 Industrial IoT Product of the Year Award—monitor gas, liquid, or vapor supply lines. If the pressure within a line, machine, pump, or specialized area (e.g., negative pressure tent or cleanroom) falls out of a user-defined range, users are alerted via text, email, or call.

Available in 50, 300, 750, and 3000 pounds per square in gauge (PSIG) meters, these sensors use a five-volt pressure transducer to measure the pressure within a supply line. Collected data is transmitted to iMonnit Sensor Configuration and Management Software for analysis and action.

Work-Site Ready

These wireless pressure meters are available in industrial-grade and AA battery-powered enterprise-ready sensors.

• AA-battery meter options: an on/off switch and a line-powered device with battery backup
• Added industrial options: intrinsically safe, IECEx-certified ALTA-ISX 300 PSIG and high-gain leaded puck antenna

Below, you can explore the wireless pressure meters counted on by utilities, hospitals, factories, refineries, manufacturers, universities, and agricultural firms worldwide.
