Passive Nuclear Level Transmitter TLT-PN-ET Series

TLT-PN-ET Series

TLT-PN-ET Series passive nuclear level transmitter uses Naturally Occurring Gamma Ray Sensing technology for non-contact material level detection. It does not require drilling into the hopper and is not affected by high ash temperature. Also, it provides 4–20 mA output, two relay contacts, high and low level alarms, IP66 protection and 316 stainless steel shell material. As a result, it suits ash hopper and dust collector level monitoring in thermal power plant applications.

  • True non-contact detection
  • NOGS-based technology
  • No hopper drilling required
  • High/low level alarm
  • IP66 protection

    Frequently Asked Questions

    TLT-PN-ET Series is used for non-contact ash hopper and dust collector level monitoring, mainly in thermal power plant applications.
    It uses Naturally Occurring Gamma Ray Sensing technology, also called NOGS.
    No. The datasheet highlights that it does not require drilling holes in the hopper.
    It is not affected by high ash temperature because it works as a non-contact external detection system.
    The transmitter provides 4–20 mA output and two relay contacts for high and low material level alarms.
    Users should check hopper size, ash level alarm points, number of probes, power supply, output requirement, mounting arrangement and monitoring requirement.
