iTrans Stand Alone
  • O2, toxic or combustible gas detector
  • Corrosion resistant housing
  • Dual sensor platform (on-board & remote placement)
  • 4-20 mA and ModBus RTU output

Enclosed within an explosion-proof stainless steel housing, the Stainless Steel iTrans™ is built to withstand corrosion in harsh environments such as offshore drilling platforms, chemical plants or applications near a saltwater coastline.

The iTrans monitors employ an intelligent electronics platform to provide maximum flexibility, superior performance and lower installation costs. The three or four wire system allows gas sensors to be mounted on-board or remotely up to 200 meters away, and can accommodate more than 200 transmitters in RS485 bus configuration. Able to monitor any combination of gases for a specific environment, iTrans™ uses our industry-proven “smart” sensor technology and safety features including automatic sensor recognition, zero and cal fault protection, and access code security.

The microprocessor-controlled transmitters are capable of independent operation or multi-point system configuration and can transmit a 4-20mA signal or ModBus RTU digital output to any control device or PLC. With optional on-board relays, the monitor has the added ability of stand-alone operation, activating alarms, horns, or fans and can also shut down a system without the need to wire back to a central control panel.

iTrans also offers a relay deactivation feature to prevent accidental alarm activation during calibrations. The units also feature simple non-intrusive calibration, ultra-bright LED display, programmable alarms, and on-board sensor life indicators.
