PDM-2 multi-channel fluorescence tracer particle detector Introduction: The PDM2 multi-channel phosphorescence (fluorescence) tracer particle detector is mainly used for measuring parameters such as the residence time of solid particles in the flow field of gas-solid two-phase flow. The fluorescence signal of the tracer particles passing through the front end of the probe in two-phase flow is transmitted to the photodetector (PMT) at the back of the probe, and converted into the corresponding electrical signal. Obtain the residence time of tracer particles in the reactor through computer collection and processing. The entire equipment consists of a PDM2 multi-channel phosphorescence (fluorescence) tracer particle detector host, 2-8 probes, probe cables, and application software. Features: 1. The product size is small and has little interference with the flow system 2. The instrument can simultaneously connect 2, 4, 8, or 16 probes, and can simultaneously measure 2, 4, 8, or 16 measurement points in real time 3. Each channel is equipped with baseline and high voltage regulation functions, and the sampling frequency (1Hz-2kHz) and sampling data volume are adjustable 4. The system software functions include: raw data collection and display. Real time or playback display of voltage time curves for each channel; Save voltage time data for each channel, calculate and save the time mean of each channel voltage, and calculate the statistical values and time information of the segment data. Can set and save operating parameters including sampling frequency, sampling points, range selection, measurement point position or sensor settings, as well as operating conditions (flow rate, temperature, pressure); The saved data files can be shared by EXCEL software. The application measurement software can run in a Windows environment. Technical parameters: Instrument models: PDM2-2, PDM2-4, PDM2-8, PDM2-16 Applicable environment: temperature 0-60 ℃, pressure<0.4MPa (standard probe) Measurement range: The measured tracer particle velocity is less than 40 m/s Measurement method: Contact based online measurement Probe size: Standard probe measuring end face diameter 10mm, probe rod length 400-1000mm Note: Not applicable to transparent experimental equipment.
