Remote sensors cut costs with wet-to-wet differential pressure transducer
May 11, 2012 // Julien Happich
Installation costs can be lowered with the new wet-to-wet differential pressure transducer introduced by Boiswood.
By using remote sensors, the Multi-Sense 231RS from Setra Systems can significantly cut installation and materials costs, as well as shortening set-up times. The sensors are installed directly into the pipe, with their electrical connections to the main housing being made via cables or conduit, which significantly reduces labour costs. Measurement start-up time is also cut, as purging air from the lines is no longer necessary. Materials costs are also reduced, since the copper piping that connects traditional pressure transducers is eliminated.
These savings make the 231RS a cost-effective replacement for traditional wet-to-wet differential pressure sensing technologies. The transducer can be used in the most demanding applications, such as in energy systems management, process control, liquid or gas flow measurement, and pressurised vessel liquid level measurements.
Available in both conduit and cable versions, the 231RS has four unidirectional and bidirectional switch selectable pressure ranges. Field-selectable outputs are true 4-20 mA, 0 to 5, 1 to 5 and 0 to 10 VDC, and push-button zero and remote zero capabilities are included as well as a jumper-selectable port swap. CE marked and RoHS compliant, the units have a cast aluminium construction with NEMA4 rated housings. An optional LCD is available for greater readability of output.

Internet of Things (IoT) manufacturer Ciseco has launched the Raspberry Pi ‘Wireless Inventors Kit’ (RasWIK), featuring 88 pieces to provide everything a Pi owner needs to follow a series of step-by-step projects or to create their own wireless devices, without the need for configuration or even writing code.
RasWIK has been designed to be highly accessible, demystifying the dark art of wireless and enabling anyone with basic computing skills to begin building wireless devices with a Raspberry Pi. You can create anything from a simple traffic light, to a battery monitor, or even a temperature gauge that sends data to the Xively IoT cloud so billions can access the data.This month, Ciseco is giving away twelve Raspberry Pi Wireless Inventors kits, worth £49.99 each for EETimes Europe's readers to win.
And the winners are...
In our previous reader offer, Farsens was giving away five kits for EEtimes Europe readers to evaluate its FenixVortex, Kineo and X1 wireless, battery free sensor tags.
Lucky winners include Mr A. Neil from the UK, Mr. E. Delvaux from Belgium, Mr Lengal from the Czech Republic, Mr H. Bijlsma from the Netherlands, and Mr G. Pfaff from Germany. All should be receiving their packages soon. Lets wish them some interesting findings with their projects.
