Show ESAB what you are welding with your rebel and you could win a new Sentinel welding helmet
E
SAB know that many of its customers have received their new Rebel welding units and are busy working
on a variety of projects. Now the company want to see how the go-anywhere, weld-anything Rebels are getting jobs done.
Send in your photographs to ESAB for a
chance to win a new Sentinel A50 welding helmet. Even if you don’t win the helmet, everyone who sends in a valid photograph will receive a free Rebel T-shirt.
ESAB Sentinel™ A50 is a high-performance automatic welding helmet. The helmet’s radical new design incorporates ergonomic headgear and maximum adjustability to increase productivity, functionality and usability.
If you do not have your Rebel you can also sign up for a free Rebel demonstration. Visit
www.esab.co.uk to enter or to arrange a free Rebel demonstration.

Alicat Adds EtherNet/IP and DeviceNet to Controllers and Meters
licat Scientific has expanded its communications protocol offerings, adding EtherNet/IP and DeviceNet as options on its line of mass flow, pressure, and liquid instrumentation. The new industrial automation protocols enable integration of Alicat instruments with PLCs running EtherNet/IP or DeviceNet. Real time data–including mass flow, volumetric flow, pressure, temperature, selected gas calibration, setpoint, and totalised flow of gases–can be read centrally by the PLC and used to manage Alicat controllers and meters. Users may change setpoint or gas selection, and issue other commands to Alicat instruments using a DeviceNet or EtherNet/IP enabled PLC or computer. With response times as low as 100 ms, Alicat controllers rapidly and precisely monitor and control critical process parameters in chemical, medical, manufacturing and power industries.

One and two input Counters simplify applications in
hazardous and safe areas
B
EKA associates new one and two input pulse Counters can economically perform industrial counting functions. All models have large easy to read displays with optional back-lighting, dual alarms plus isolated pulse and 4/20mA outputs. The two input Counters can display the sum or difference of the inputs and when configured for use with a quadrature encoder, the position and speed of a shaft or cable can be shown.
Intrinsically safe models with international certifications may be installed in gas and dust hazardous areas. For applications in Zone 2 or 22, Ex nA and Ex tc approval of the stainless steel model permits installation without zener barriers or galvanic isolators, significantly reducing cost. Counters can be supplied configured with engineering units for no additional charge or easily configured on-site.
