The newest and most sophisticated gas detector in ATI's product line, the D12 gas detector offers features and options to meet every requirement
The Series D12 from ATI has four different configurations: Loop Powered Transmitter
For measurement and data transmission to remote display and alarm equipment, the D12 will operate in 2-wire mode (except for combustible gas).
Loop Powered with HARTTM
For plants operating with Hart protocol communications systems, the D12 gas detector can be supplied with this option.
Transmitter with Integral Relays
For gas detection systems requiring local alarm functions, or systems where discrete outputs are desired, the D12 can provide 3 relay outputs.
Transmitter with MODBUSTM
When RS485 communication is desirable the D12 transmitters with alarm relays can be supplied with ModbusTM interface. |
- LCD graphic display - gas concentrations are displayed in large easy to read numbers
- Internal data logger - gas values are stored at user definable intervals and can be recalled when needed
- Non-intrusive operation - not necessary to open enclosure when making adjustments
- Password protection - user selectable password to prevent unauthorised changes
- Modular electronics
- Explosion proof enclosure - designed for operation in hazardous areas
- Scaleable 4-20mA output range
- Three internal alarm relays programmable for setpoint, hystereses, on-delay, off-delay and other variables including remote reset
- Analogue output simulation - provides a complete loop testing without the need to apply gas to the sensor
- Relay output simulation - output and alarms may be inhibited for maintenance and calibration
- Serial communication interface
- Interchangeable sensors - accepts up to 48 different sensors greatly reducing the need for multiple transmitter modules
- Smart sensors store calibration data, allowing sensor to be calibrated separately from the transmitter
- Sensor calibration history
- Sensor response verification provides reliable response checks to insure system integrity
