Sensing your sensors

Monnit’s Industrial Resistance Sensors can be retrofitted quickly to scientific sensors or equipment, such as batteries, that are used in the process and manufacturing sectors.

A popular transducer interface solution for passive resistance loads up to 250K Ohms, Monnit’s sensors awake at user-specified times to monitor a resistive load. Captured analogue data is then calculated into a resistance measurement. If the observed resistance deviates from user-set thresholds, the user is notified via text, email, or call. Instant alerts prevent unnecessary (and costly) downtime or the loss of research and irreplaceable samples.

Monnit’s Industrial Resistance Sensor reads the resistance across any resistive load and reports back the measured resistance. The resistance sensor leads are meant to connect to passive devices only, connecting the sensor leads to any voltage or power source may damage the sensor. It is programmed to sleep for a user-given time interval (heartbeat) and then wake up, convert the analogue data, mathematically compute the resistance, and transmit the data to the gateway, where it is then logged into the cloud service. The user can configure defined thresholds and have the system alert on threshold breaches.

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

• Resistance Monitoring
• Battery Monitoring
• Transducer Interfacing
• Elevator Monitoring
