digital flow sensor 数显流量传感器dfs 系列产地: 日本型号: dfs-1-odfs-1-0 a single unit offers three functions:flowswitch, flow sight, and flow meter.
.gif.gif featuresthis sensor has a seven-segment led digital display to makeyouread flow rate value easily.you can select one of two different kinds of output types:pnpoutput or npn output.this sensor is used with a connector (m12×4-pin).you can use the digital flow sensor with an input powersupplyof from 12 to 24 v dc (permissible voltage fluctuation ±10%).the amplifier protection structure conforms toip67equivalent.you can set the lower limit of the flow rate. if the flowratefalls below this limit, the red led lamp (ng) turns on, andcontactsignal output is given to notify the operator of thecriticalsituation.in the case of low pressure specifications, you can checktheflow of fluid by observing the rotor rotation.you can use the sensor at the desired installationposition(horizontal, vertical, or tilted position) and in thedesiredinflow direction.rotor can be cleaned by air removing the cap from the frontofthe main body.

※1： you can not see fluid if the metal cap (for high pressure)isinstalled.
※2： we adjust each type of sensors at our factory in accordancewithfluid type. please specify the type of fluid you intend 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. see thedfsinstruction manual on how to configure.
※6： we also sell a single article of sensor cable. please askus,for details.
principle of actuation.gif the detection part of digital flowsensorutilizes rotation of the rotor (turbine) installed in thepassage.the measuring part detects, by means of the externalmagneticsensor, the rotational speed of the permanent magnetmounted on thecircumference of the rotor. you can select npn outputor 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
