LT / LR / PA 

LLT / LR / PA systems

Telco PA detection systems can be used in any application you can imagine, in the most difficult working conditions. They are extremely compact, with a detection range of up to 70 meters. They can be used as a transmitter / receiver or probe. Different forms of transmitter / receiver construction are available. Easy alignment allows quick and safe mounting. Telco also offers you a wide range of PA amplifiers, MPA multiplexers and PAB "bus" amplifiers which, in combination with the appropriate sensor, form a single and complete system.
