TM6 magnetostrictive series with outer buoy


TM6 series magnetostrictive level transmitters can measure liquid level, interface level, and temperature at the same time. TM6 is designed according to the magnetostrictive principle, which is a highly accurate, respond fast, good reliability, long life, maintenance free, smart level measuring instrument because the gauge can′t be effected by pressure, temperature, dielectric coefficient and so on. Magnetostrictive level transmitter is widely used in the applications of petroleum, chemical, food , water treatment, food processing, pharmacy, tanks management, etc.

TM6 MLT can adjust null point and range remotely because of its HART or RS485/MODBUS protocols. Parameters including units, display upper/lower limits, damping, shift correction, correcting upper/lower limits, D/A trimming correction, restore factory setting and so on, can be configured through three buttons in cases and LCD.


  ※ two-wire system 4-20mA with HART

  ※ both zero point and range can be adjusted remotely and locally

  ※ self-diagnosis and fault output alarm

  ※ Non-volatile memory to prevent data loss

  ※ Good stability, simple installation, maintenance free, low cost

  ※ Measure liquid level, interface level and temperature at the same time

  ※ Optional lightening integrated connecting terminal

  ※ Multifunction LCD field indicator

  ※ The whole explosion proof design, explosion proof screws lock cover

  ※ Double grounded junction port inside or outside to field ground

  ※ Outside hang-tag hole

  ※ Prompt with junction port on meter case (field terminals )
