Acoustic Locator LKA
Acoustic pig detector LKA-00 with bag and box. / LKA-00 amplificador de sonido de diabolos de limpieza

Work of acoustic locator LKA-00 is based on amplification of the noises created by the pigs moving through a pipeline.

These noises occur every time when a pig traverses a circumferential weld and cups or cleaning elements scrap against the pipe wall. For example by the number of sounds in one batch an operator can say how many polyurethane cuffs has the approaching PIG.

Due to it's high sensitivity the acoustic locator allows to "to hear" a PIG motion on a distance of up to1,5...2 km along any pipeline.

The geophone can be placed in the ground directly over the pipe. Geophone is connected with control unit by a cable with length 10m (longer cable by request). It allows to "listen" a PIG while sitting in a car.

CONVENIENCE AND EASINESS IN USE

For convenient attachment of geophone to exposed parts of a pipeline like vent pipes, valves, fittings etc. it is equipped by a small magnetic clip.

A wide range of allowable operating temperatures, water resistant remote geophone (acoustic sensor) and a water tight control unit, allows to use this acoustic locator in all climatic conditions.

All regulation and switching of device operation modes are performed by means of two buttons on the control unit. Listening is conducted on high-quality headphones.

For visualization of received signal strength and for amplification level adjustments there is an indicator with 8 LEDs on the from panel. The brightness of LEDs is automatically regulated by photocell.

While listening there is a possibility for quick adjustment of amplification level as well as selection among three frequency ranges which pass-bands are optimized for distant, middle and close PIG detection.

Electric batteries of common type LR 6 are used as a source of power supply in LKA-00. The device has low power consumption and maximizes the use of batteries to their full discharge.

The control and adjustments of acoustic locator are made intuitive and easy. Short clear instructions is supplied. The instructions are written in English and Russian.
