The iTrans fixed-point gas monitor employs an intelligent electronics platform to provide one or two points of detection from a single head for maximum flexibility, superior performance and lower installation costs.
Able to monitor any combination of gases for a specific environment, iTrans utilizes our industry-proven “smart” sensor technology and safety features including automatic sensor recognition, access code security, and zero and cal fault protection – all enclosed within an explosion-proof aluminum or stainless steel housing.
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.

Feature |
Benefit |
Single or dual channel configuration |
Flexible platform allows for any combination of sensors. Lower price point per channel for monitoring more than one gas in an area. |
ModBus RTU interface |
Allows system integrators to connect iTrans to SCADA, HMI, and PLC systems. |
Remote sensors |
Sensors are designed to be mounted remotely from the iTrans head (up to 200 meters away) or in a stand-alone fashion (in ModBus applications). |
Non-intrusive calibration |
Allows field calibration in hazardous locations. |
LED display |
Large, bright display that can be seen from across plant; easy to read in dark environments. |
On-board relays |
Enables user to activate alarms, horns, fans, locally without the need for a controller. |
Low-cost |
Extremely low price per point of detection |
Push button/keypad operation |
Intuitive, easy-to-use interface makes it simple to program alarms, set relays, zero, calibrate, and change span gas settings. |
Field upgradable “smart” sensors |
Second sensor can be added at any time in the field. Sensor type can also be changed in the field. |
Programmable alarms |
Programmable low and high alarms for each channel; flashing alarm message on LED display activates to indicate hazardous conditions. |
