Senseca OMNI-HR1MV-ISO Flow Meter / -switch

Flow Meter / Switch / Indicator OMNI-HR1MVFor commissioning, the sensor supports a simulation mode for the analog output. It is possible to create a programmable mA value atthe output (without modifying the process variable). The range is 0..20 mA. This enables the commissioner to test the run betweenthe sensor and the downstream electronics.The complete housing can be rotated around the mechanical connection, and so after sealing, the correct position for readingcan be set. Operation is through dialog with the display messages.It is possible to reset to the factory settings at any time.Technical data Sensor Nominal width Process connection ● ● ● ● ● ● ● ● ●Viscosity stabilised from 30 to 200 mm²/s 0/4..20 mA or 0/2..10 V output signal2 x programmable switches (push-pull) Backlit graphical LCD-Display (transreflective), can be readin sunlight and in the dark Programmable parameters via rotatable, removable ring(programming protection) All metal housing with scratch and chemical resistantglass Unit is displayed (selectable) Rotatable electronic head for best reading positionParameter interfaceCharacteristics The electronics can be used on the spot to set switching valueswhere process values are exceeded or fallen short of. This setting can be carried out via the display even without a process. Thepresent values or error messages from the measuring point are visible at any time, and all major parameters can be accessed onthe spot. The analog current signal can be evaluated from large distances, and the present values can be made available there. Ifdesired, the sensor can be configured at the factory with your parameters. It is therefore ready for immediate use, withoutprogramming. If you wish to change parameters, you can set the device directly at the sensor, by means of the programming ring.The entire family of OMNI sensors is made up in a modular way, by means of a building-block system (hardware and software). A 16-bitmicrocontroller with a 14-bit A/D converter and a 12-bit D/A converter ensure the necessary processing speed and accuracy.The signal is displayed with the unit of measure by a backlit LCD graphical display, and is converted into a 0/4..20 mA signal. Twoswitching values with a choice of PNP or NPN output can be programmed across the whole range. The hystereses of theswitching values can be set separately in value and direction (min., max. switching value).Exceeding or falling short of switching values, and error messages, are indicated by a flashing red LED visible from a long distance,together with a message in the display.Further parameters can be modified by means of a code:Signal filter, selectable unit (l/min, m3/h ...) incl. automatic conversion of the values, selectable output 0..20 mA, 4.0.20mA,0..10 V or 2..10 V, value assignment of 0/4..20 mA or 0/2..10 V (setting of zero point and range).pi-ho_fki-omni-hr1mv_e V1.03-00Metering range Qmax.Tolerance Pressure resistance Media temperature Ambient temperature MediaWiring Supply voltage Power consumption Analog outputanalog hall sensorDN 32..50 female thread G 11/4..G 2 (further process connections available onrequest) 2..220 l/min for details see table "Ranges" to 250 l/min ±3 % of the full scale value plus viscosityvariationPN 200 bar -20..+85 °C optionally -20..+150 °C -20..+70 °C water, oils (gases and aggressive mediaavailable on request) see section "Wiring" 18..30 V DC <1W0/4..20 mA, 0/2..10 V via a 500 OhmW resistance after 0 V.Switching values PNP or NPN, selectable, 300 mA max. load S1+S2 in total, programmable as min. value or max.value, resistant to short circuits, reversal polarity protected.Display backlit graphical LCD-Display (transreflective), extended temperaturerange -20..+70 °C, 32 x 16 pixels, background illumination, displays value andunit, flashing LED signal lamp with simultaneous message on the display.Ingress protection IP 67 Electrical for round plug connector M12x1, 5-poleconnection Materials Brass construction:Stainless steel medium-contact CW614N nickelled, construction: 1.4571, CW614N, 1.4310,1.4404, 1.4310, hard hard ferrite ferrite PTFE-coated,DN 32..40: NBRDN 32..40: FKM Materials, nonCW614N, PPS, glass medium-contact Weight see table "Dimensions and weights"Installation Standard: horizontal inwards flow; other location installation positions are possible; theinstallation position affects the display, metering and switching range.1
