Agilent 410105004 is an original motor-sensor assembly designed to operate the 6-port valve in the pneumatic section of the Agilent G1888 Headspace Sampler. The assembly provides mechanical valve actuation together with position sensing for correct routing of gas and sample flow paths during automated headspace analysis.
Function in the Headspace Sampler
The motor-sensor assembly operates the 6-port valve used to route gas and sample through the headspace sampler pneumatic path.
Its functions include:
- mechanically switching the valve between operating positions,
- accurately positioning the valve mechanism,
- detecting the current valve position,
- providing feedback to the instrument control electronics,
- synchronizing valve operation during the headspace sampling cycle.
Correct motor and sensor operation is important for reproducible transfer of headspace sample into the GC.
Assembly Design
G1888 service documentation identifies the motor-sensor assembly as including components such as:
- 24 VDC valve motor
- 6-port valve terminal block
- optical position sensor
- motor-support bracket
- motor-sensor disk
- coupling
- associated mounting hardware
The product is therefore the valve drive and sensing assembly rather than the complete fluidic 6-port valve itself.
Compatibility
410105004 is intended for: Agilent G1888 Headspace Sampler
