digital flow sensor 数显流量传感器dfs 系列产地: 日本型号: dfs-8-wdfs-1-0 a single unit offers threefunctions:flowswitch, flow sight, and flow meter. featuresthis sensor has a seven-segment led digital display tomakeyouread flow rate value easily.you can select one of two different kinds of outputtypes:pnpoutput or npn output.this sensor is used with a connector (m12×4-pin).you can use the digital flow sensor with an input powersupplyoffrom 12 to 24 v dc (permissible voltage fluctuation ±10%).the amplifier protection structure conformstoip67equivalent.you can set the lower limit of the flow rate. if theflowratefalls below this limit, the red led lamp (ng) turns on,andcontactsignal output is given to notify the operator ofthecriticalsituation.in the case of low pressure specifications, you canchecktheflow of fluid by observing the rotor rotation.you can use the sensor at the desiredinstallationposition(horizontal, vertical, or tilted position) andin thedesiredinflow direction.rotor can be cleaned by air removing the cap from thefrontofthe main body.

※1： you can not see fluid if the metal cap (for highpressure)isinstalled.
※2： we adjust each type of sensors at our factory inaccordancewithfluid type. please specify the type of fluid youintend to usethesensor with when you place your order.
※3： value for max. flow rate at viscosity 32 cst.
※4： you can select the non-display mode.
※5： you can configure alarm flow rate optionally. seethedfsinstruction manual on how to configure.
※6： we also sell a single article of sensor cable. please askus,fordetails.
principle of actuation the detection part of digitalflowsensorutilizes rotation of the rotor (turbine) installed inthepassage.the measuring part detects, by means of theexternalmagneticsensor, the rotational speed of the permanentmagnetmounted on thecircumference of the rotor. you can select npnoutputor pnp outputoptionally. ask数显流量传感器dfs-1-o日本asd原装进口全国免费送货上门详情请询问我公司(tel:0512-55179360） ask数显流量传感器dfs-2-o日本ask原装进口全国免费送货上门详情请询问我公司(tel:0512-55179360） ask数显流量传感器dfs-3-o日本ask原装进口全国免费送货上门详情请询问我公司(tel:0512-55179360） ask数显流量传感器dfs-6-o日本ask原装进口全国免费送货上门详情请询问我公司(tel:0512-55179360） ask数显流量传感器dfs-8-o日本ask原装进口全国免费送货上门详情请询问我公司(tel:0512-55179360） ask数显流量传感器dfs-2-w日本ask原装进口全国免费送货上门详情请询问我公司(tel:0512-55179360） ask数显流量传感器dfs-3-w日本ask原装进口全国免费送货上门详情请询问我公司(tel:0512-55179360） ask数显流量传感器dfs-6-w日本ask原装进口全国免费送货上门详情请询问我公司(tel:0512-55179360） ask数显流量传感器dfs-8-w日本ask原装进口全国免费送货上门详情请询问我公司(tel:0512-5517
