The Plymovent light sensor, LS-12, is intended for use with the Plymovent energy savers and automatic dampers as an alternative to the inductive sensor clamp. It is used as an alternative when welding with gas or TIG at less than 30A. The inductive sensor clamp reacts to the induced magnetic field around the cable and is insensitive to currents of less than 30A. The light sensor, however, reacts to slight light changes. It 'sees' the light change when welding starts or stops and, in conjunction with the energy savers or automatic dampers, automatically starts or stops the fan or opens or closes the dampers. The light sensor may be fitted to the hood of the extractor, or wall mounted. Sensitivity may be adjusted so as not to react to the light cartridge in the hood. If required the photocell can be connected in parallel with the inductive sensor clamp. The light sensor is delivered with 5m cable.
Features
- Perfect alternative to the inductive sensor clamp when the latter cannot be used due to the type of welding taking place
- Reacts immediately to slight light changes
- Connected in parallel with the inductive sensor clamp will widen the spectrum of usage of the system
- Simple to mount
