Pressure SwitchesEDS 300 - Shipbuilding<strong>About</strong> EDS 300 Pressure Switches:The EDS 300 is a compact, electronic pressure switch with digital display. The pressuremeasurement is based on a thin film strain gauge sensor cell in stainless steel. All partsin contact with the fluid are in stainless steel, and are welded together. Since no sealsare required in the sensor chamber, leakage is eliminated.Two relay switching outputs with N/O function and an additional analog output signal (4to 20 mA) enable the pressure switch to be incorporated into the most modern controlconcepts. The switching points and the corresponding hysteresis can easily be adjustedvia the keypad.For optimum adaptation to a particular application, the unit has many additionaladjustment parameters, e.g. switching direction of the relays, switching delay times.Areas of application are pressure or maximum value monitoring on marine transmissions,diesel engines, pumps and general hydraulic and pneumatic systems.Technical Details:Input DataMeasuring ranges-14 to 75, 150, 1000, 3000, 6000, 9000 psi-1 to 5, 006, 016, 040, 100, 250, 400, 600 barOverload pressure200, 300, 3000, 7000, 11000, 13000 psi15, 15, 32, 80, 200, 500, 800, 900 barBurst pressure400% FSOutput DataAccuracy (display, analog output)≤ ±1% FS max.Repeatability≤ ±0.5% FS max.Temperature drift≤ ±0.3% / 10 K zero point max.≤ ±0.3% / 10 K range max.Analog output4 to 20 mA, ohmic resistance ≤ 400 ΩSwitching OutputsType2 relay contacts (N/O)Switching voltage10 mV to 60 V (AC or DC)Switching current0.01 mA to 1AMaximum switching output30 W / 30 VA(for inductive load, use varistors)Life expectancy20 million (min. load)0.5 million (max. load)Reaction timeapprox. 10 msAmbient ConditionsTemperature range of medium-13° to 176°F (-25° to 80°C)Ambient temperature range-13° to 176°F (-25° to 80°C)Storage temperature range-40° to 176°F (-40° to 80°C)Nominal temperature range-14° to 158°F (-10° to 70°C)markEN 50081-1, EN 50081-2EN 50082-1, EN 50082-2Vibration resistance5 to 25 Hz: 3.2 mm25 to 500 Hz: 4 gOther DataSupply voltage20 to 32 VDCElectrical connectionplug to DIN 43651 (6 pole + earth)Current consumptionapprox. 100 mASafety type IP 65Hydraulic connectionG 1/4 A male, (torque rating approx. 15 lb-ft)SAE 4 female thread (torque rating approx. 6 lb-ft)Parts in contact with fluidstainless steel, FPM sealMaterial of housingtube: stainless steelkeypad housing: PA6.6 Gf30Display4-digit, 7 segment LED, redWeightapprox. 300 gApplications:Approvals:American Bureau of ShippingNo.: 00-ES 19976-XLloyds Register of ShippingNo.: 00/20048Det Norske VeritasNo.: A-7710 (895.10)Germanischer LloydNo.: 15519-00HHBureau VeritasNo.: 10343 /A0 BV25Electronics Catalog
