This product has been discontinued and is no longer available. In many cases we can still service and calibrate it. Talk to our team about spares or alternatives.
The SharpEye 40/40L combines UV and IR sensors, with the IR sensor operating at 2.5-3.0 um to detect hydrocarbon fuel and gas fires, hydroxyl and hydrogen fires, and metal and inorganic fires. High-speed dual-sensor logic delivers detection with strong immunity to false alarms.
KEY BENEFITS
- UV/IR dual-sensor detection
- High-speed response - 150 msec to saturated signal
- Solar blind operation
- Detects hydrocarbon, hydroxyl, hydrogen, metal and inorganic fires (40/40L)
- Heated window for snow, ice and condensation conditions

Dual UV/IR sensing with high-speed response
Model 40/40L (and LB, with Built-In-Test option) provides a combination of UV and IR sensors, where the IR sensor operates at a wavelength of 2.5-3.0 um and can detect hydrocarbon-based fuel and gas fires, hydroxyl and hydrogen fires, as well as metal and inorganic fires.
Model 40/40L4 (and L4B) is identical to the 40/40L except that the IR sensor works at 4.5 um and is suited to hydrocarbon-based fires. The detector senses radiant energy in the short-wave section of both the ultraviolet and infrared spectrum, analysing frequency, intensity and duration, and triggering an alarm only on simultaneous UV and IR detection.
A special UV logic circuit helps prevent false alarms caused by solar radiation, while a heated window, 5-year warranty and SIL2 approval make the detector a robust choice for critical applications.
Benefits
- UV/IR dual-sensor detection
- High-speed response - 150 msec to saturated signal

The 40/40L IR sensor operates at 2.5-3.0 um and detects hydrocarbon, hydroxyl, hydrogen, metal and inorganic fires, while the 40/40L4 IR sensor works at 4.5 um and is suited to hydrocarbon-based fires.
It triggers an alarm only on simultaneous UV and IR detection, and the UV sensor includes a special logic circuit that helps prevent false alarms from solar radiation.
The dual-sensor detector delivers a high-speed response of 150 msec to a saturated signal.
The B versions add the Built-In-Test option for automatic and manual self-testing to assure continued reliable operation.
It carries a 5-year warranty, an MTBF of at least 150,000 hours and TUV SIL2 reliability approval.
