Protecting your investment in transmission equipment is a major consideration in today’s high tech applications. Altronic Research has developed the Fiber Optic Interlock Monitor or Leak Detector exactly for those concerns. The Fiber Optic Interlock Monitor is designed for use in high RF environments and senses the presence of any liquid where sensors are installed to protect wave guides, coaxial lines, filters, combiners, and dummy loads. The sensors detect fault conditions and will shut the transmitter off before extensive damage can occur to ancillary equipment. Its simplified design allows user installation and is expandable to multi-channel/multi-function operation.
