Weatherproof level measurement and object detection

Packaged in a weatherproof housing, Monnit’s Industrial Ranging Sensor measures levels or detects objects. Indoor and outdoor applications include vehicle/object detection, capturing liquid levels, and tracking inventory. If a monitored variable varies from a user’s preset limits, the sensor issues an alert via text, email, or call.

Monnit’s Ultrasonic Sensors can be used in various applications to measure distances between the sensor and objects in its path. These ultrasonic sensors are impervious to target surface and colour and feature autocalibration algorithms which allow them to adapt to variable environmental conditions and compensate for temperature and humidity effects.

Level Detection Made Easy

As a battery-powered sensor, Monnit’s device installs quickly because there’s no wiring to an additional power source. This modularity is ideal for silos, tanks, loading docks, and other difficult-to-network applications. 

The Ultrasonic Sensor sends out a high-frequency sound pulse and then times how long it takes for the echo of the sound to reflect back. The sensor has two openings on its front. One opening transmits ultrasonic waves (like a tiny speaker), the other receives them (like a tiny microphone). The ultrasonic sensor uses the speed of sound and time difference between sending and receiving the sound pulse to determine the distance to an object. It will take readings at set intervals and report the data back to the iMonnit software portal, where the information is processed to display distance and alert users if a defined condition is met. All sensor data is then stored for historical analysis.

WARNING: Tanks with liquid in them must be vented, otherwise condensation will accumulate on the lens and render readings inaccurate.

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)
• 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
• 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

Applications

• Liquid level detection
• Object/vehicle detection
• Inventory status (based on distance measurement)
• Loading bay occupied status
