Description
Sartorius volume comparator for determining the volumes of solids, especially of weights.Special performance features:- Monolithic weighing technology- Calibration of the volumes of objects with masses of 1 g to 1 kg according to the buoyancy method- Highly accurate differential weighing in liquid- Load receptor for individual weights of any shape and of density standards and density reference spheres- Fully automatic measurement sequence for any combinations up to 1 kg- Closed weighing chamber in liquid equipped with feedthroughs for the load alternator, sensors, weighing pan and loading device- The water batch completely surrounds the weighing chamber in liquid- Automatic load alternator with 9 positions in liquid (FC40)- Second automatic load alternator with 9 positions for measuring the mass of substitution weights in air- 2 temperature sensors (PT100) in the weighing chamber with measuring bridge, readability of 0.001°C- Additional sensors for air temperature, relative humidity and air pressure are integrated in the weighing chamber for air- Measurement equipment and controls in two separate cabinets with access to all components- Industrial standard PC with TFT monitor- Software for control and calculation of density values- Control panel with ports for additional networking (USB, LAN)- Thermally insulated and closed measurement cabinet contains water bath in liquid and built-in load alternator sensors in air and liquid, motor for lifting and rotating mechanism, and a granite slab for the mass comparator with feedthrough for below-balance weighingTechnical SpecificationsMaximum capacity 1110 gApplication range 1 g - 1 kgReadability 10 µgRepeatability, at 1/2 load 20 µgRepeatability, s* 30 µgRepeatability (typical), s* 15 µgDensity uncertainty < 1 kg/m³Volume uncertainty < 0.00015 cm³Electronic weighing range & taring range 610 gSubstitution weights 500 gLinearity 100 µg / 600 gOff-center loading error 15 µg / mmRange sensitivity 10 µg / 2 gStabilization time 15 sBasic EquipmentLoad alternator 2x9Interfaces LAN|USB|RS232Draft shield xEnclosure xControl unit xPC xPC software xAir temperature sensor 1Air moisture sensor 1Air pressure sensor 1Liquid temperature sensor 2Test certificate BEVClimate station xMeasuring liquid FC40 40 kgAmbient ConditionsPermissible operating temperature range 17-27 °CRecommended operating temperature 22 °CTemperature fluctuation 0.1 °C/h|0.3 °C/12hMax. air movement < 0.2 m/sHumidity range 40-60 %Humidity fluctuation 5%/4hPower supply 100-240V AC/50-60HzDimensionsWeighing pan diameter 90 mmSample size(DxH) 6-95x120 mmDiameter range for a silicon sphere 8-100 mmWeigh cell (WxDxH) 220x440x305 mmMeasurement unit (WxDxH) 600x600x1600 mmControl unit (WxDxH) 600x600x1600 mmFilling capacity, tempering bath 65 lFilling capacity, measurement cell 24 lOptimal height for setup 400 mmOptimal room height ≥ 3000 mmApplicationsOIML R111, class E1 1 g - 1 kgASTM E617, class 0 1 g - 1 kgOptional AccessoriesExternal calibration weight 500 g|E2 YCW552-02Weighing table YWT20CThermostat YVT01CDensity reference (Si) 200|500|1000gDensity reference (Zerudur) 200|500|1000gDensity reference, weight set 1 g - 1 kg YCS31-612-09* Repeatability is the standard deviation "s"; it is calculated from 6 ABBA cycles, after eliminating drift.Prerequisites for the standard deviation are good climatic conditions in accordance with the OIML R111 Guideline.Setup and installation by our special mass comparator technicians from Germany is required.
