7 Day Mechanical Timer Replacement Clock Drive 220V 50Hz SKU: TE-5007-4X

7 Day Mechanical Timer Replacement Clock Drive 220V 50Hz

The TE-5007-4X is a replacement clock drive mechanism for 7-day mechanical timers used in high volume air samplers. This precision timing component ensures accurate sampling schedules for TSP, PM10, PM2.5, and PUF sampling systems operating on 220 volt, 50 Hz electrical systems.

Technical Operation

This mechanical clock drive mechanism operates the timer's bright yellow dial through a series of precision gears and escapements. The 7 day mechanical timer uses a series of on/off trippers to set the sampling schedule, with the clock drive providing the rotational movement that advances the timer dial and activates sampling periods. The 220V 50Hz motor configuration is specifically designed for international applications and regions using European electrical standards.

Key Specifications

• Voltage: 220 volts AC
• Frequency: 50 Hz
• Timer cycle: 7 days
• Operating temperature: Standard ambient conditions

Compatibility

This replacement clock drive is compatible with TE-5007X complete 7-day mechanical timers operating at 220V 50Hz. It serves as the internal drive mechanism for timers used in:

• Mass flow controlled and volumetric flow controlled high volume air samplers
• TSP samplers with mass flow controllers
• PUF pesticide samplers housed in aluminum shelters
• PM10 and PM2.5 particulate monitoring systems

Installation and Maintenance

This clock drive assembly replaces the internal timing mechanism when the original drive fails or requires service. Installation requires disassembly of the timer housing and precise alignment of the gear train. Tisch Environmental uses only high quality components to ensure reliability and consistency in field applications.

Regular inspection of the clock drive mechanism helps prevent sampling interruptions. Signs that replacement may be needed include irregular timer advancement, failure to complete 7-day cycles, or mechanical binding during operation.

Applications

The TE-5007-4X supports environmental professionals who need reliable, repeatable data for regulatory monitoring, research projects, and industrial studies. These systems are available with either a 7 day mechanical timer or a US EPA recommended digital timer to ensure accurate sampling results, with the mechanical option providing dependable operation in remote locations where power interruptions may affect digital systems.
