Serveron TM1 On-Line Dissolved Gas Monitor

Brand: Qualitrol Company

The Serveron® Model TM1 offers a breakthrough price/ performance point in on-line DGA.

For the first time, the benefits of on-line condition monitoring can be realized across the distribution transformer fleet.

The Serveron® TM1 continuously monitors and reports hydrogen PPM Levels and can be programmed to alarm based on PPM Levels and/or Rate of Change (ROC), warning operators of potentially disruptive transformer faults and pending failures.
Features
  • Responds only to Hydrogen: no cross interference or composite measurements.
  • Rapid step change response facilitated by active oil circulation over the sensor itself.
  • Single Valve mount
  • Low Cost of Ownership:
  • No Membrane – directly immersed sensor
  • No Sensor replacement or recalibration required for life of monitor
  • No Consumables or routine service required
