Mass Flow Controller (MFC) PC Board - Brush Motor - 110V 50/60Hz SKU: TE-300-310-1

Mass Flow Controller (MFC) PC Board - Brush Motor - 110V 50/60Hz

The TE-300-310-1 is a precision Mass Flow Controller (MFC) PC board assembly designed specifically for brush style high volume air sampler systems. This controller board maintains constant volumetric flow rates by continuously monitoring and adjusting motor speed based on real-time airflow measurements, ensuring EPA-compliant sampling for ambient air quality monitoring applications.

Technical Operation

The MFC PC board utilizes thermal mass flow sensing technology to measure actual airflow through the sampling system. The controller compares measured flow rates against user-defined setpoints and automatically adjusts the control valve to stabilize flow when deviations occur. The integrated control circuitry provides precise feedback control to the brush motor assembly, compensating for filter loading, temperature variations, and atmospheric pressure changes that would otherwise affect sampling accuracy.

Key Specifications

• Input Power: 110 volts AC, 50/60 Hz operation
• Motor Type: Designed for brush style motor assemblies
• Control Method: Closed-loop mass flow control with thermal sensing
• Response Time: Fast adjustment for maintaining stable flow rates
• Operating Environment: Suitable for outdoor ambient monitoring installations

Compatibility

This MFC PC board is compatible with Tisch Environmental brush style high volume air samplers operating at 110V. It works with the complete TE-300 series brush motor controllers, including the TE-300-310 complete MFC assembly. For 220V applications, see the TE-300-310-1X board. This board is specifically designed for brush motor systems - for brushless motor applications, use the TE-300-310-1BL brushless MFC board.

Installation and Maintenance

The PC board mounts within the controller housing and connects to the flow sensor, motor drive circuitry, and user interface components. Regular calibration verification is recommended using certified flow standards to maintain measurement accuracy. The board includes diagnostic capabilities to monitor system performance and alert operators to maintenance needs or system faults.

Applications

This MFC board is essential for environmental testing applications, controlling gas flows in emissions testing, air quality sampling, and environmental research. It ensures compliance with EPA reference methods for TSP, PM10, and PM2.5 ambient air monitoring by maintaining the precise flow rates required for accurate particulate concentration measurements. The controller is suitable for both routine monitoring networks and specialized research applications requiring high accuracy flow control.
