Laser based moisture and water sensor
Using a laser beam tuned to the resonant frequency of an H2O molecule, the SA1W sensor is able to detect any liquid or paste containing water molecules - without any contact!
When a customer in the packaging industry wanted to detect breaks in a line of glue laid down for sealing packing material, he found he had a problem Similarly, a contact lens manufacturer wished to detect if solution had failed to be impregnated in contact lens blister packs

IDEC Analogue Modules
Following the recent launch of the higher density analogue modules for the IDEC PLC Pentra and MicroSmart range, IDEC have also upgraded the original 2 and 3 channel analogue and thermocouple modules
In both cases they were advised to use the SA1W.
Using a laser beam tuned to the resonant frequency of an H2O molecule, the SA1W sensor is able to detect any liquid or paste containing water molecules - without any contact!.
Capable of detecting liquids through clear or translucent containers of any colour, the SA1W uses a small diameter laser beam for precise detection and has a visible red spot for easy targeting and alignment.
The high power type has successfully been used to sense the level of liquids through dark thick material; one application was to detect the level of alcohol based drinks in bottles where the air space in the bottle has to be closely controlled to prevent the stoppers blowing off!.
The high power SA1W handles this situation with ease even where labels are stuck on both sides of the container/bottle.
