Flow Switch with Digital Display for Oil Water Air PNP NPN Relay Optional

Product Overview:HFM510 digital explicit flow switch adopts the principle of thermal diffusion, which is applied in flow detection to show the value of regional temperature difference corresponds to the size of flow.Its working principle is to place a heating module and a temperature sensing module in the closed probe. The temperature difference value of the heat transfer of the probe is closely related to the velocity of the measured medium. When the medium in the pipe flows at a stable velocity, the sensor module receives a fixed value that the heating module senses.When the velocity of flow through the probe changes, the thermal sensing module will send out the temperature difference signal, and the processor will output the result of the corresponding velocity.HFM510 digital explicit flow switch does not have any moving parts, so compared with mechanical flow switch, it will not fail due to corrosion, fracture, baffle deformation and other reasons.It is also suitable for flow monitoring of different media, including some impure liquid and gas media.Insert installation mode, meet various pipe diameter installation requirements.The product USES digital display medium flow state;Button setting parameters, easy to operate;Long service life combined with maintenance-free design.The products are widely used in industrial furnace, welding equipment, laser equipment, microwave equipment, glass machinery, lubrication machinery, printing machinery, machine tools, as well as large transformer and other fields.Parameters:  Measuring RangeWater1...150cm/s (Most sensitive range 1...60cm/s)Oil3...300cm/s(Most sensitive range 3...100cm/s)Air20...2000cm/s(Most sensitive range 20...700cm/s)Measuring MediumWater, Oil, AirWithstand Voltage100barInitialization Time18sResponse Time1...15s, related to thermal conductivity of medium, typical value 2sSupply Voltage24VDC(18~32VDC)No-load current
