Fast response flow switch
1 November 2013
New SBY flow switch from ifm electronic feature very quick reaction
For those occasions where a critical flow needs to be signalled rapidly to avoid serious consequences to downstream equipment, sensor market leader ifm electronic has released new versions of the SBY range.
Following the binary output devices capable of detecting a presence or loss of a flow within less than 0.01 seconds, ifm has now launched the SBY433 and SBY434 which provide the same fast response, but with a 4 to 20 mA analogue signal.
The setting range of the SBY433 covers 1 to 25 litres/minute, while the SBY434 can be set between 2 and 50 litres/minute, in each case with minimal pressure loss.
As featured in the binary SBY, the analogue SBY is simple to adjust via the calibrated setting ring. Both have Rp ¾ process connection and operate on a nominal 24V DC.
Permissible medium temperatures range from +10 to +85°C, and while the data are stated for water, the materials in contact with the medium such as stainless steel, nickel-plated brass and industrial plastics mean that flows other media can be signalled.
The typical application is cooling water, so for applications such as cooling circuits in induction furnaces, the SBY flow switch range from ifm electronic is indispensible.
ifm is committed to working closely with its customers to develop products which precisely match their needs, and the company provides expert, readily accessible technical support to help users maximise the benefits they gain from ifm products.
