Luxtron® m920 OEM Series

Fiber Optic Temperature Sensing for Semiconductor OEMs Between -100 to 330 ⁰C

Advanced Energy’s Luxtron® four-channel m924 and two-channel m922 semiconductor modules are designed for etcher and wafer fab equipment temperature monitoring of electrostatic chucks, chambers and other devices.

The complete Luxtron® m920 series OEM solution is built using the electronics module assembly with two boards plus probes. The main board contains fiber optic temperature sensing channels, digital output (RS232 ASCII and RS485 Modbus), and power connection. The analog output board provides 0 to 10V or 4 to 20 mA output and is mounted above the main board. An optional metal enclosure is also available.

The m920 series system uses Fluoroptic® technology. The m920 series main board conditions the measurement of the signal from Fluoroptic probes and reports a calibrated temperature to the OEM control system.
