Motor Controller/Elapsed Time Indicator, 110V, 60Hz SKU: TE-5010

Motor Controller/Elapsed Time Indicator, 110V, 60Hz

The TE-5010 Motor Controller/Elapsed Time Indicator is an essential control component for high volume air sampling systems, providing both motor voltage control and precise elapsed time tracking for EPA-compliant ambient air quality monitoring applications. The elapsed time indicator functions as a mechanical clock that counts the hours and minutes that the instrument is actively collecting a sample, serving as a critical device for tracking motor life, motor brush changes, and verifying sampling time.

Motor Control and Timing Functions

This motor controller uses a manual motor speed adjustment device to control the motor speed, allowing operators to regulate airflow rates in high volume air samplers. The integrated elapsed time indicator provides accurate documentation of sampling periods, which is essential for calculating pollutant concentrations and ensuring regulatory compliance with EPA monitoring protocols.

Technical Specifications

• Voltage: 110 Volts
• Frequency: 60 Hertz
• Control Type: Manual motor speed adjustment
• Timing Display: Hours and minutes elapsed time
• Operation: Mechanical clock mechanism

System Compatibility

The TE-5010 is compatible with high volume air sampling systems that include a motor, timer, flow controller, elapsed time indicator, outdoor aluminum shelter, and pressure recorder. It works with both brush-style and brushless motor configurations across TSP, PM10, and PM2.5 sampling applications. The controller is designed for installation within anodized aluminum shelters that house the timer, magnehelic gauge, vacuum motor, elapsed time indicator, flow venturi, and sampling modules.

For international applications requiring different voltage and frequency specifications, consider the TE-5010X (220V, 50Hz) or other voltage-specific variants in the TE-5010 series. Brushless motor applications require the TE-5010-BL or TE-5010-BLXZ controllers.

Applications

The TE-5010 supports high volume air samplers commonly used in air quality monitoring to determine the concentration of total suspended particulates in ambient air, operating at constant flow rates over set sampling periods to collect particulates on filter media. These applications include air quality monitoring and industrial hygiene where accurate and reliable measurements of particulate matter are essential.

Operational Benefits

The elapsed time tracking capability is crucial for motor maintenance scheduling, brush replacement intervals, and sampling time verification. The manual motor control allows operators to adjust flow rates based on specific sampling requirements and changing filter loading conditions throughout the sampling period.
