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.
