Simtronics DG-TX7 is a series of gas detectors by Teledyne supplied with a pair of OXYCOL catalytic sensors and compensated circuitry, detecting a range of flammable gases including Hydrogen. DG-RX7 are the Syntel model versions.

Designed to be used in harsh environments providing 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 hard wired HART protocol option, providing installation options and reduced service costs. Relay operation and alarm levels can be set using the TLU which is hazardous area approved.

Features

  • Range 0 to 100% LEL
  • Response time T90 < 15 s (Methane)
  • Easy to use
  • Ultrabright 4 digit LED display, shows local status by display colour & alarm level.
