Morgan Hill, Calif., July 7, 2002 -- Profacture Corporation, today announce the release for sale of their new Tegal® 90X Flow Switch Conversion Kit.

Tegal® 90X Series Etchers have been delivered with magnetic reed type flow switches since their introduction. These switches have a tendency to accumulate particles and get stuck in the open or closed position. The risk of this is having the system alarm/fault unnecessarily or worse, in the event coolant is not flowing the system does not alarm or fault. 

The engineers at Profacture have developed a field conversion kit that incorporates a paddle type flow switch. Fluid flowing through the switch spins a magnetic rotor to induce voltage in a coil. This voltage is measured by a simple electronic circuit, which compares it to a user-set trip voltage. When the voltage is above the set point, a relay is held in its active position. If the voltage falls below the set point, or should the fluid stop flowing, the relay is switched off and triggers the system to alarm and or fault.
