Topas: Measuring instruments

This optical method counts and sorts particles independently, one by one, according to their size, without any a priori asumptions. It is very fast, offer excellent sensitivity and accuracy. One other advantage is that relation between the optical effect and size is straightforward and intertrepation is easy. Alongside we offer a loarge range of accessoiries and software for one by one counting, measurement of concentration with very high resolution and high sensitivity in a very large range of concentration.

The EMS electromagnetic vibrator has been specially designed for use with microsieves dia.75 mm. Vibration amplitude can be adjusted manually to match any powder condition and provide excellent reproductibility. It can be used for microsieving, angle of repose measurement, vibration of small objects (powder column, dosing funnel). Specification Clamp for sieves 75 mn, Frequency 100/120 Hz (on 50/60 power). Amplitude : Max.1 mm ; amplitude range : 10 %...100 % ; 230 VAC 50/60 Hz (operation at 110 V requires step up transformer) ; 70 x 140 x 270 mm (Tripod : dia.15 mm, 480 x 200 x 320 mm) ; weight : 3.1 kg (Tripod : 3.7 kg). CE Marked.

GMS 141 Gravimetric Measurement System In-situ-concentration measurement of blow-by aerosols Additonal particle size information by use of two wavelengths No condensation due to heatable measurement chamber Integrated sheath air Comfortable detection of oil content in blow-by after oil mist separators with a filter blank sheet or filter cartridge directly on engines or engine test stands Two independent sections : bypass and measuring. Running up to the working point over bypass section and measuring over measuring section. Prevention of undesirable filter charging. Switching between both sections with pneumatic ball valves ; feature : manual or automatic switching (by default time or differential pressure) Heatable absolute filter box in order to avoid condensation (up to 110 °C) Advantages : Time-saving reproducible detection of oil content after oil mist separator in blow-by of combustion engines Installation of two different absolute filters possible. Selection by flow rate and filter charging : Filter blank sheet with 110 mm diameter or Filter cartridge with 65 mm diameter, L = 93 mm Two independent sections : bypass and measuring. Running up to the working point over bypass section and measuring over measuring section. Prevention of undesirable filter charging. Switching between both sections with pneumatic ball valves ; feature : manual or automatic switching (by default time or differential pressure) Heatable absolute filter box in order to avoid condensation (up to 110 °C) Display for differential pressure at absolute ­filter (information about filter charging) Display for blow-by-temperature and absolute filter temperature Convenient device control with web browser Easy to use, rugged, space-saving design Specification : Flow rate : up to 300 l/min (18 m3/h) ; Installation : in-line ; Differential pressure measuring range at filter box : 100 hPa ; Pipe connection diameter : DN 28 mm Dimensions of absolute filter Filter blank sheet : 110 mm diameter (effective diameter100 mm/filter area : 78,5 cm²) Filter cartridge : 65 mm diameter, L = 93 mm filter area : 679 cm² Aerosol contacted materials stainless steel, aluminium, FKM Heatable filter box < 110 °C (adjustable) I/O-System analog and digital out-/input, PC connection via TCP/IP Compressed air supply 3…8 bar Power supply 230 V AC/50 Hz, 3 x 200 W, 3 A Dimensions W x D x H 520 x 240 x 350 mm Weight 14 kg.
