150-Watt DM Transmitter
The Loc-150Tx is a powerful 150-watt transmitter — the go-to choice for cable fault locating, finding holidays on coated pipes, and tackling deep-buried lines and long-distance pipe and cable runs. It is typically used with the Defect Mapper (DM) receiver on cathodic-protected longline pipelines, but is equally well suited to anyone needing a low-frequency, high-output transmitter.
Selectable frequencies from 98 Hz to 640 Hz cover longline work, and the two-inch backlit dot matrix display shows output current, volts, resistance, frequency, volume and high-voltage warnings. Two rotary/push control knobs give quick access to frequency, output level, menu information and active/standby modes.
Supplied with a direct connection lead, DC input lead, AC mains lead and ground stake, and packaged in a rugged, ergonomic IP54 housing, it delivers consistent current output with protection against inadvertent connection to voltages up to 250 V.
