Other features and benefits
  • Dual Gas Sensing: The iTrans 2 can detect and display up to two gases on certain models. Both gas sensors may be mounted directly to the transmitter, or may be mounted remotely.
  • Wide Sensor Offering: The iTrans 2 supports Electrochemical, Catalytic Bead and Infrared sensors. The iTrans 2 is available for most common industrial gases, allowing of standardization for your gas detection equipment.
  • Smart Sensors: The iTrans 2‘s smart sensors come factory pre-calibrated and automatically send sensor information, such as sensor life, to the transmitter. A sensor life indicator is displayed immediately after each calibration.
  • Dual-channel split-screen LED display: For optimum visibility in dark places
  • Non-Intrusive Calibration: The iTrans 2‘s non-intrusive interface keys operate with a simple magnetic wand and allow for full transmitter configuration and calibration without opening the unit’s explosion-proof housing.
  • Programmable Relays: The microprocessor-controlled transmitters are capable of independent operation or multi-point system configuration. 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.
  • Multiple Wiring Options: The iTrans 2 can be configured to meet almost any installation application. Common configurations includes: 3-Wire (4-20mA) Models - Allow for full utilization of the iTrans 2‘s features and options and can be used with all of the iTrans 2‘s sensors / 4-Wire (Digital ModBus) Models - Allows for full utilization of the iTrans 2‘s features and options and can be used with all of the iTrans 2‘s sensors.
  • HARTTM Communication Protocol: With the optional HART Communication Protocol, the iTrans 2 offers remote diagnostics, set-up or calibration by super - imposing a high-frequency current across the industry standard 4-20mA analog line.
  • Stainless Steel Enclosure: An optional stainless steel enclosure for corrosive environments.
