Find Class 1 Division 2 Data Loggers and Custom Enclosures
Explosions, fires and corrosion pose ever-present dangers to electrical instrumentation operating in heavy industrial environments. OSHA and other organizations classify work areas according to the presence of flammable materials or gases. For data capture in Oil & Gas, Chemical, and other processing applications, users require specially-protected data loggers
At CAS DataLoggers we have provided a number of solutions for data logging in hazardous locations. We can help you to pick the ideal device for your application.
Capturing Data in Hazardous Environments:
Hazardous locations are standardized as Classes and Divisions based on their level of exposure to gases, liquids, dusts etc. which can potentially result in a fire or explosion. To record data in these areas, users need devices with special protection against flammable substances and explosions.
If you need to capture data in these locations, first determine the Class/Division rating of the hazardous area and then source a datalogger rated for operation within it.
- Class I Hazardous locations contain flammable gases or vapors in the air in concentrations sufficient to produce explosions or other ignitions. Class I locations are then further classified as one of two Divisions and one of three Zones.
- Class II Hazardous locations contain combustible dust in hazardous concentrations. Class II locations are then further classified into two Divisions.
Data Loggers for Use in Hazardous Areas:
CAS DataLoggers offers Class 1, Division 2 data loggers designed to record data in areas where flammable liquids, gases, etc. are processed, often where ventilating equipment isn’t functioning correctly.
Our first preference is to locate the data logger outside of the hazardous area, trailing the appropriate sensors inside the area, and then to use safety barriers to route the signals from the sensors to the logger. This provides the advantage of easy access to the data logger for data retrieval, program changes, and other maintenance.
However, due to distance or other considerations, this is not always practical. Therefore we offer a selection of data logging equipment suitable for direct use in hazardous areas to collect Temperature, Humidity, Pressure or other types of data.
A popular example is the dataTaker DT80-Ex, an intelligent logger with an extensive array of features that allow it to be used in many applications. This robust, stand-alone, low-power data logger features USB memory stick support, 18-bit resolution, extensive communications capabilities and a built-in display. The dataTaker DT80’s Dual Channel concept allows up to 10 isolated or 15 common referenced analog inputs to be used in many combinations.
Custom Enclosures Available:
We can also provide standard data logging systems housed in explosion-proof enclosures for use in hazardous areas, but because of their cost, size and weight we typically use these only if there are no other practical options.
