MicroSensor MFM500A PNP NPN Relay Intelligent Liquids Water Flow Switch

PNP NPN Relay Intelligent  Liquids Water Flow Switch MFM500A   Product DescriptionMFM500A Flow Switch is an intelligent thermal diffusion principle based flow monitoring sensor. It adopts ARM processing core and combines with high quality sensors and dedicated circuit. With temperature-compensation and calibration, it can ensure measurement accuracy in the case of water temperature change. It is available for real-time monitoring of pipe water flow. It can be used for cooling or lubrication system flow monitoring to realize pre-warning and protection for critical equipment when there is flow fault. It uses fully enclosed design, stainless steel construction to adapt to a variety of application environment. It is with overvoltage, over-current and reverse polarity protection function. With self-luminous OLED screen, it allows switchable display between the progress bar and digital display numbers.MFM500A supports quick action point set, also it has display inversion function that enables installation in any direction, and no need for frequent adjustment and maintenance. It can be applied for operation protection of large equipment in fields such as power generation, metallurgy, steel, paper, boilers etc.  Product Feature• Optional power supply 24VDC or 220VAC• OLED screen, switchable display between the progress bar and digital display• All stainless steel housing, IP67 protection• Temperature compensation• 2-way PNP /2-way NPN /1 relay output are optional /2-way PNP+4~20mADC• No moving parts, maintenance-free• Switch output, control point setting continuously on panel• Compact size, support inverted display• Mounting joint can be equipped with different interfaces for a variety of pipe diameters requirement Specification Measure Range:1cm/s~150cm/s (water);Optimal Range: 3cm/s~100cm/s (water)Power Supply: (24±4.8)V DC / 220VACWorking Current: ≤ 60mASwitch Accuracy: ±10cm/sHysteresis: ±2cm/s~±8cm/sInitial Time: 2s~15s, 8s(typ.)Switch-off Time:1s~15s, 2s(typ.)Switch-on Time:1s~13s, 2s(typ.)Output Signal: 1 relay2 NPN2 PNPOutput Function: NO, NC(optional)Relay Characters:Switch voltage: ≤ 250V AC / 30V DC  Switch current: ≤3ATransistors Characters:  Switch Voltage Drop: ≤ 1.5V  Switch Current: ≤ 400mADisplay: OLED indicator, resolution 128×32Electric Protection: Reverse, short-circuit,Over-voltage Housing: S.S.Button: PPProbe: S.S.Installation: Joint mounting + adaptorEndurance Pressure: 10MPaSet: ButtonElectric Connection: M12×1 5-pin plugGross weight : 265gWater Temp. : -20ºC~80ºCStorage Temp. : -30ºC~85ºCWorking Temp. : -20ºC~70ºCProtection: IP67Temperature Compensation: 5ºC~50ºC(water)Electromagnetic Compatibility: GB/T17626.2/3-2006, GB/T 17626.4-2008Shock: ≤3g (GB/T JJG 882-2004)              Impact: ≤ 50g/11ms (GB/T 2423.5-1995)Note: The above specification test medium is water; 5cm/s~100cm/s; 20ºC(Factory defaults)Outline Construction:(Unit:mm)Order Guide MFM500AFlow Switch   CodePower Supply  DC24VDC  AC220VAC    CodeProcess Connection C1M20×1.5 male adaptor(MS601) C3G1/2 male adaptor(MS602)   CodeOutput J1×Relay Output N2×NPN Transistor Output P2×PNP Transistor Output   CodeProbe Length L115mm L218mm L321mm L468mm   MFM500A  DC      C3     J        L1                     Whole Spec.    CertificationsCompany Profile  Products Family   FAQ 1. Q: Are you manufacturer or trading company?    A: We are 48-year professional manufacturer of Pressure/ Level/ Temperature/Flow transmitters with 4~20mA, Hart, Rs485 & Modbus protocols, pressure sensors with SDI, I2C, 4~20mA, 0.5~4.5V and etc, and wireless IOT measurement transmitters.
