Loc-150Tx、150 瓦 DM 發射器主要與缺陷映射器 (DM) 接收器一起使用，但它也適用於需要低頻、高輸出發射器的用戶。
通常，Loc-150Tx 發射器（DM 發射器）用於向陽極床施加信號電流。管道通過塗層故障將信號返回到變送器。 Loc-150Tx 發射器設計為由 CP（陰極保護）站、交流電或外部電池供電，無需內部電池。該發射器具有直接連接模式，可將定位頻率應用到導體上。沒有箝位或感應模式。
Loc-150Tx 發射器具有從 98Hz 到 512Hz（歐洲為 640Hz）的可選直接連接頻率。帶 LED 背光的 2 英寸 x 1 英寸點陣顯示器顯示輸出電流、電壓、頻率和過壓/過溫/過功率警告。
兩個旋轉/按鈕控制旋鈕提供對頻率選擇、輸出電平、菜單信息和活動/待機模式的訪問。該變送器配有直接連接線、直流輸入線和交流電源線。

The Loc-150Tx, 150-Watt DM Transmitter is used primarily with the Defect Mapper (DM) Receiver, however it is also useful for those needing a low frequency, high output transmitter.
Typically, the Loc-150Tx, transmitter (DM transmitter) is used to apply a signal current to the anode bed. The pipeline returns the signal via coating faults back to the transmitter. The Loc-150Tx transmitter is designed to be powered from CP (Cathodic Protection) stations, AC or external batteries, eliminating the need for internal batteries. This transmitter has a direct connection mode to apply the locate frequency onto the conductor. There is no clamp or induction mode.
The Loc-150Tx transmitter has selectable direct connection frequencies from 98Hz to 512Hz (640 Hz in Europe). The two inch by one-inch dot matrix display with LED backlight shows output current, volts, frequency, and over voltage/over temperature/over power warnings.
Two rotary/push control knobs provide access to frequency selection, output level, menu information and active/standby modes. This transmitter is supplied with a direct connection lead, DC input lead and AC mains lead.
