SonAire® Intrinsically Safe C1D1 Rated Sensors for Fuel and Flammable Chemicals

Massa Products Corporation: The MassaSonic® SonAire® M3is Series sensors consist of battery operated wireless level sensors capable of intercommunicating using ZigBee RF Modules. The M3is versions are intrinsically safe rated for CIDI, zone Ø and CID2 environments. These sensors possess detection ranges from 4″ (100 mm) to 13′ (4 m). Two models are available, the M3is 95 kHz ranges from 12” (300 mm) to 13’ (4 m) and the M3is 150 kHz ranges 4” (100 mm) to 7’ (2.1 m).

The narrow beam sensors incorporate advanced ultrasonic technology and provide precision non-contact distance measurement for industrial or liquid level process control and tank monitoring. The M3is is unique compared to all other systems because of its exceptional ease of operation, affordability, and ability to be installed and calibrated without using a target. The sensor housing material is all Kynar (PVDF) to offer superior chemical resistance in the toughest industrial environments.

The SonAire® Sensors are RoHS compliant, and the package is rated for high-pressure washing and immersion in compliance with IP67. The batteries are universally available lithium AA type and are easily accessible for replacement. Typical battery life is 4 years.

SonAire® M3is Sensors are available for use in hazardous environments. The SonAire® M3is Sensors are certified by Factory Mutual as complying to the requirements of Class 1 Div 1 (C1D1), All Groups, which is the maximum rating. Standard SonAire M3 Sensors are designed for operation in all standard applications. The SonAire® M3is design is well suited to monitor combustible solid or fluids materials and fixed/portable chemical tanks in remote locations or factories where environmental hazards may be an operational consideration. It has been designed keeping in mind site privacy, like cloud based inventory breaches.

The IS model is particularly effective for mining, oil patch, waste storage, wastewater operation with methane gas or chemical operations. Also suitable for silos storing grain, powder or resin that may dust and be susceptible to combustion. As the fundamentally safe version holds the highest FM certification for all groups (C1D1), it can be readily usable in lower rated areas
