Baumer expands ATEX rated sensor portfolio, IS & Ex

These days, safety at work is of central importance and this trend is going to continue in the years ahead. Baumer has responded by expanding its portfolio of inductive sensors for the ATEX sector. Whether analogue, three-wire or Namur, it is now offering new products for all three interfaces. They are insensitive to dust and other contaminants and thus ideally suited for plant in industries such as oil & gas, wood processing, paper and plastic manufacture and pharmaceuticals.The IWRM 12 linear sensor family has been designed according to the latest ATEX standards, allowing customers to incorporate the latest Ex concepts. It is easy to install and perfect for positioning in the confined spaces. It is one of the only inductive distance sensors available in an M12 housing for ATEX 2D. The sensor has a 4 mm measuring distance and gives reliable and repeatable measurements with a resolution of up to 1 micron. In the IFRM 12 three-wire version, Baumer supplies a complete portfolio for ATEX 3D. The cylindrical M12 housing is available in two lengths and PNP/NPN and normally open/normally closed versions are also on offer. There are a total of eight sensors with a 4 mm sensing distance. This flexibility simplifies sensor selection and makes the design process easier, as there is a wide range of solutions for different applications. Another benefit is that the type of ignition protection employed requires no additional electronics.

Your application all wrapped up.

imagemapThe innovative HDmag flex magnetic belt encoders MIR 3000F and MQR 3000F are particularly cost-effective solutions for measuring the position and speed of shafts with large diameters of up to 3183 mm. They are based on the tried and tested HDmag principle, the high-resolution scan of a precision dimensional scale with real-time signal processing. The sensing head has two adjustable scanning units for adaptation to any shaft diameter. The high-resolution dimensional scale is strapped onto the shaft like a belt.

Power Generation – Combustion Control


OxyFire Sensors: Typically used in a coal-fired power boiler, the high temperature, in-situ oxygen sensor is generally installed in the boiler water-wall, above the nose arch and above each of the burner banks. This configuration allows the boiler operators to center the fireball in the radiant zone and “balance” the boiler.

Typically installed above the slag line, the sensors give the boiler operators a unique perspective on the combustion process, eliminating the typical “air infiltration” that confuses “low temperature” sensors located in the back pass.

Benefits from using Marathon Monitors’ Combustion Optimization System to “trim” the draft are:

  • Balanced boiler – Centering the fireball
  • Minimizing NOx formation
  • Reduces over-all maintenance costs
Providing the operators with this type of information allows them to do their job more efficiently, eliminates CO (carbon monoxide) pockets, and helps in achieving “lowest cost” megawatts.

LOROX Low-Range Temperature Series
LOROX Sensors: Typically used in fossil fuel fired power boilers where the slag line is very high. These sensors are often installed in the back pass section where temperatures are too low for Oxyfire sensors to operate. Response time is still very fast and the LOROX is easily maintained without removal.
