ebm-papst FlowGrid – Air-inlet grill for axial and centrifugal fans


Whether it’s heat pumps in the home, condensers in supermarket refrigerators or ventilation systems on the production floor, FlowGrid, the innovative patent-pending air-inlet grill from ebm-papst, is dramatically reducing noise levels for fans installed within limited-space air moving equipment.

Its open grill design straightens airflow to minimize turbulence before the air hits the axial or centrifugal impeller blades. FlowGrid is ideal for fans installed within flat and central air handling units, air purifiers and heat pumps with centrifugal fans, or air-water heat pumps, condensers and V-shaped condensers with axial fans.

“FlowGrid is the result of our extensive airflow testing for inlet conditions with a wide variety of customers’ axial and centrifugal fans across dozens of applications,” said George Riker, business development. “By improving the aerodynamic conditions external to the fan, FlowGrid reduces the adverse effects of these inlet conditions and minimizes noise.”

With FlowGrid, ebm-papst is making a clear contribution to active noise reduction – a big part of its GreenTech philosophy. It can help manufacturers and ventilation specifiers comply with noise regulations and improve the environment for employees who work near ventilation equipment. The innovative air-intake grills, which require less acoustic insulation, work with both axial and centrifugal fans without reducing their performance. Using them can help to reduce or entirely avoid the use of cost-intensive, passive noise-reduction measures.

Grayhill, Inc. has introduced the compact Series 67B Joystick, a Hall-Effect joystick with a pushbutton and momentary knob rotation for additional interface options. The joystick travels 20 degrees in each X and Y direction as well as momentary rotation around the Z axis. With a 32mm diameter and requiring just 16mm behind panel depth, the new 67B is the smallest joystick to offer this many functions.

A hall-effect sensor provides contactless operation, facilitating a long operational life of over 1 million cycles.  The hall-effect sensor magnetically detects the shaft position anywhere within its 20-degree field of travel.  The on-board micro-controller then produces X,Y coordinates in a range from 0 at center to 50 at the extreme periphery for digital output.  It also conserves power by operating at 3mA max, with a built-in sleep mode of only 0.1mA max.

Output is via a built in micro-controller for I2C interface. I2C is a simple and flexible interface bus for communication with other digital devices. Most other joysticks of this size only offer an analog output.

The Series 67B Joystick is designed for panel mount applications where space is limited. Its integral mounting flange has 4 threaded mounting holes in a 28mm square.  This compact joystick can provide precise cursor control where other pointing devices are impractical, such as on medical electronics, work vehicles and industrial or robotic control.

Grayhill’s proven technology and quality systems ensure superior performance with minimized costs.  The 67B has been fully-tested in ISO/IEC 17025 labs to achieve electrical and environmental specs, including:

Environmental Seal: IP67 with optional sealing boot

Operating Temperature Range: -40°C to +85°C

Honeywell Basic Board Mount Pressure Sensors, Compensated, Unamplified TBP Series

Honeywell TBP 7-2014

Honeywell announced its new Basic Board Mount Pressure Sensors, Compensated, Unamplified TBP Series. These new sensors are designed for customers who require a simple, high quality, cost-effective, basic performance, mV output device. They are compensated and unamplified, ideal for customers who want a temperature-compensated sensor with the maximum possible resolution.

Wide pressure range: 60 mbar to 10 bar; 6 kPa to MPa; 1 psi to 150 psi

Small: 7 x 7 mm [0.276 x 0.276 in] is very small when compared to most board mount pressure sensors, occupying less space on the PCB and typically simplifying placement

Wide compensated temperature range: 0 °C to 85 °C [32 °F to 185 °F]

Media compatibility:

Non-silicone-gel coating: The input port is limited to non-corrosive, non-ionic media such as dry air and gases and should not be exposed to condensation

Silicone gel coating: Uses the same materials in the wetted media path but is protected from condensation by a silicone-based gel coating

Various package styles:

  • DIP (Dual Inline Pin)
  • Leadless SMT (Surface Mount Technology)
  • SMT

Various pressure ports:

  • DIP: Single axial barbed port and low-profile port
  • Leadless SMT: Single axial barbed port and low-profile port
  • SMT: Single axial barbed port and low-profile port

Gems Simplifies Your Fluid Sensor Choice



A search on Google for “sensors” delivers 38,600,000 results. Even the more specific search for “liquid level sensors” dumps 4,520,000 results in your lap. Whether you call it information overload or the Tyranny of Choice, it adds up to a daunting task as an engineer to source the ideal sensor component for a particular application.One way to simplify the search is to start with a company that has application expertise and the willingness to share it, combined with a broad portfolio of sensor product types and technologies. A conversation with a sensor application specialist can rapidly introduce the options available for a given project and, more
importantly, provide clarity on the pros and cons of a specific sensor in the context of your application.Taking this route can save time over the hit and miss results of typical internet searches. A frictionless translation of “engineering needs” to “sensor solution” is the goal of any time-constrained engineering project.
