iTrans

• O2, toxic or combustible gas detector
• Dual sensor platform (on-board & remote placement)
• Split-screen LED display
• 4-20 mA and ModBus RTU output

Cl2, ClO2, CO, CO/H2 null, H2, H2S, HCl, HCN, LEL, NO2, NO, NH3, O2, PH3, SO2

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.
