Connecting the Yokogawa EJX910 Series MODBUS with USB MODBUS Converter

The Yokogawa EJX910 multivariable transmitter serves as a differential pressure gauge, a pressure gauge, and a thermometer (with an external temperature sensor). In addition to this multifunctionality, the fluid density compensation function provided by the transmitter itself and the PC-installed EJXMVTool’s mass flow parameter configuration tool enable high-speed, high-precision mass flow rate measurement. The EJX910 supports a number of flow rate standards and a variety of fluid types as target applications. Moreover, the EJX910 can be applied to integrated flow rate measurement and various diagnoses that use many process variables (differential pressure, static pressure, temperature, etc.).

Arc Flash as it Relates to AC Drives

An arc flash (or arc blast) is a type of electrical explosion that results from a low impedance connection to ground or another voltage phase in an electrical system.

Even without electrocution, death or dismemberment may occur through an intense arc blast, up to 35,000 F deg, and force up to 2100 psi from the intense heat rapidly expanding the air, copper & particles creating a shockwave blast.  Droplets of molten metal and shrapnel can penetrate the body.

The presentation below explains:

  1. What is arc flash 
  2. OSHA, NFPA 70E
  3. Codes and standards 
  4. Protective clothing and equipment
  5. Prevention
