Thumbnail Filmstrip of TE-300-310-2 Mass Flow Controller Flow Probe - Brush Motor Compatible Images
The TE-300-310-2 is a precision flow probe designed specifically for Tisch Environmental brush style mass flow controllers. This critical sensor component measures gas flow rates in EPA-compliant ambient air sampling systems by detecting thermal changes in the gas stream.
Technical Operation
The flow probe operates on thermal mass flow measurement principles, utilizing a mass flow sensor within the main flow path. The probe generates a precise flow signal that enables the MFC's closed-loop control system to maintain accurate flow rates for air quality monitoring applications. The thermal sensor measures flow by introducing controlled heat into the gas stream and monitoring temperature differentials.
Key Specifications
- Designed for brush motor MFC systems
- Thermal mass flow sensor technology
- Calibrated for ambient air applications
- EPA-compliant measurement accuracy
- Operating pressure range: 50-300 kPa differential
Compatibility
This flow probe is engineered for use with Tisch Environmental brush motor mass flow controllers, including:
- TE-300-310 (110V brush motor MFC)
- TE-300-310X (220V brush motor MFC)
- TE-300-310-1 (110V MFC PC board)
- TE-300-310-1X (220V MFC PC board)
Important: This probe is specifically designed for brush motor systems and is not compatible with brushless motor MFCs (TE-300-310-BL series). Using incorrect probes can result in inaccurate flow measurements and system malfunction.
Installation and Maintenance
The TE-300-310-2 probe requires careful installation to ensure proper thermal contact and flow measurement accuracy. The probe requires calibration specific to the gas being measured, typically ambient air for EPA monitoring applications. Regular inspection for contamination or physical damage is recommended to maintain measurement precision.
Applications
Essential for EPA-compliant ambient air quality monitoring systems including TSP (Total Suspended Particulate), PM10, and PM2.5 sampling. The probe enables precise flow control required for 40 CFR Part 50, Appendix B, Appendix J, and Appendix L reference methods, ensuring accurate volumetric flow rates critical for regulatory compliance.
