Simtronics DG-TX7 is a series of gas detectors from Teledyne, supplied with a pair of OXYCOL catalytic sensors and compensated circuitry, capable of detecting a range of flammable gases, including Hydrogen. The DG-RX7 range has a Syntel output.

Designed to be used in harsh environments, as long as Oxygen is present. In the absence of O2, an alternative monitor equipped with a thermal conductivity sensor is available.

Part of the MultiTox DG7 family, all detectors have a universal platform for standardised maintenance and training.

Microprocessor-driven, configurable using a wireless hand-held terminal (TLU) or by using a hard-wired HART protocol option, providing installation options and reduced service costs. Relay operation and alarm levels can be set using the TLU, a hazardous-area-approved device.

Features

  • Range 0 to 100% LEL.
  • Response time T90 < 15 s (Methane).
  • Ultrabright four-digit LED display, shows local status by display colour & alarm level.
  • 4-20mA output &  2 x configurable relays.
  • Compatible with most controllers and PLCs.
  • Power supply 24V DC.
  • Housing corrosion-resistant Stainless Steel.
  • Ingress Protection IP66.
  • Approvals ATEX & IECEx.
  • Weight 4 Kg.
  • Range previously by Simrad Optronics.

Output Signal Options

  • HART Protocol 7th edition (facilitating nonproprietary interface).
  • Lonworks (Syntel).
  • 0-22mA (User configurable).
