AvCount Sample Delivery Unit – SA1950-0
A compact system with a single push-button operation used to feed viscous samples into AvCount2 (SA1000-2) and AvCount Lite (SA1800-0). Suitable for use when viscosities exceed 68 mm2/s and up to 200 mm2/s.
Comprises a compressor and a sample pressurization chamber. A sample bottle is placed on the sample platform and the platform is raised into the pressurization chamber where it is pressurized to 3 bar by an integral compressor. The sample passes to the particle counter under pressure via the sample delivery tube. The delivery tube contains a non-return valve to prevent sample leakage when the sample delivery system is disconnected from the particle counter.
Safety devices include a pressure relief valve to protect against overpressure and a mechanical interlock that prevents an operator from opening the pressurization chamber when it is pressurized.
