Always know supply line pressure

Monnit’s Industrial Wireless Pressure Meter monitors 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, an alert will be sent in real time via text, email, or call.

Available in 50 and 300 pounds per square inch 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.

By connecting the sensor to a pressurised gas, liquid, or vapor supply line, you can measure the pressure within the line and review the data in the iMonnit Online Sensor Monitoring and Notification System. The data is stored in the online system and can be reviewed within the system on dashboards and charts or exported as a data sheet or graph. You can customise settings to your use case and set notifications and alerts in the cloud-based software to know immediately via text, email, or call if the pressure is above or below an optimal range.

A lab – and machine – ready sensor

This sensor comes with an industrial battery included with the life of up to 7 years.

All industrial sensors are enclosed in a reliable, weatherproof NEMA-rated enclosure that are constructed for both indoor and outdoor use. These rugged enclosures protect the sensor circuitry against;

• Falling dirt
• Wind-blown dust
• Rain, sleet, snow, splashing water, and hose-directed water
• Ice formation on the enclosure
• Increased resistance to corrosion

Features

• Impressive wireless range of up to 1,200 feet through walls
• Frequency-hopping spread spectrum (FHSS)
• Improved interference immunity
• Improved power management for longer battery life
• Encrypt-RF® Security (Diffie-Hellman Key Exchange + AES-128 CBC for sensor data messages)
• Over-the-air updates
• Free iMonnit basic online wireless sensor monitoring and notification system to configure sensors, view data and set alerts via SMS text and email
• Stores 2000 to 4000 readings if gateway connection is lost (non-volatile flash, persists through the power cycle)
  • 10-minute heartbeats = ~ 22 days
  • 2-hour heartbeats = ~ 266 days

Applications

• Compressed air supply lines
• Water supply lines
• Gas supply lines
• Pumping systems
• Irrigation system pressure
• Industrial process monitoring
• Trash compaction equipment
• HVAC/R
• Chemical Processing
