Model IR400 - Infrared Point Gas Detector (IR)
From Gas Detectors
The Model IR400 Infrared (IR) Point Detector is a microprocessor-based hydrocarbon gas detector that continuously monitors combustible gases and vapors within the lower explosive limit (LEL) and provides alarm indication. All electronics are contained within an explosion-proof housing so that the IR400's detector information can be processed locally. The IR400 operates with a 4-20mA signal, which is proportional to 0 to 100% LEL gas concentration at the detector. Configurations with analog output, Modbus and HART are also available. Modbus and HART data can be used for predictive maintenance.
Features & Benefits
- Industry-leading speed & response: T90 ≤ 3 seconds even with splash guard installed
- No routine calibration required reducing maintenance costs
- Industry standard 4-20 mA output provides remote alarm and fault indication
- Multiple communication outputs provide complete status and control capability in the control room
- Heated optics eliminate condensation
- Dirty optics indication discriminates between true fault and cleaning requirements
- Fast calibration times reduce amount of cal gas required which lowers maintenance time and costs
