The device is designed for a cleaning devices searching in gas pipes in case of its sticking and tunnelling mechanism localization.

The system consists of a special electromagnetic emitter, which is implemented into the cleaning hedgehog and analogously into the easily portable mobile receiver and probe set. The optical and acoustical indicator of the measurement signal level is a part of the receiver. The receiver is equipped with a connector for the possibility to the state control and accumulator charging without the need of the device demounting and accumulator removal. The same connector can serve except of the accumulator charging to the measuring probe connection.

Power supply:	receiver	maintenance-free hermetic accumulator V / 1,2 Ah, geometrical dimensions: 42 mm x 96 mm x 52 mm (for example WP type 1,2-12)
	emitter	10 pieces of primary cells R6 - AA - 1,5 V (for example WP type 1,2-12)
Operation:	receiver	in the typical searching mode, when sometimes the first green indicator lights, is at least 16 h. During the signal acquisition signalised by the first two indicator columns it is min. 6 h.
	emitter	is fully operable in 6 h. (or according to the requirements) after turning on, then the minimum operating time is 12 h.
Position:	receiver	arbitrary, usually on the neck sling
	emitter	arbitrary (given by the cleaning hedgehogs position)
	probe	approximately vertically to the surface and gas pipes
Range:	typically	±5 m (in front of and behind the position of emitter)
Signalisation:	optical	by the colour column imaging triplet
	acoustical	for the pre-set signal intensity
Dimensions:	receiver	60 mm x 210 mm / 1,8 kg
	emitter	63 mm x 150 mm / 1,3 kg
	probe	75 mm x 30 mm / 1,3 kg
Environmental resistance		0°C až 40°C, IP 56 for emitter, IP 44 for receiver
