TinyHawk™ – “Keep the surface clean”

The TinyHawk™ is designed to detect oil contamination on static background (concrete, floor, water) in continuous unattended mode. When oils are detected, the sensor can give out an ALARM which is sent via 4-20 mA standard,MODBUS, etc. Sensing, processing and alarms are done continuously in real-time mode.

The sensor operates at ultraviolet (UV-A) excitation wavelength in pulsed mode. UV-light, upon coming into contact with oil contamination will cause the re-emission of incident light with a specifically up-shifted wavelength (fluorescent light). This fluorescence is then detected and processed by the sensor – when reaching a certain signal threshold the ALARM is reported.

FEATURES

No false alarms caused by other than oil objects
All weather design
Applicable in hazardous locations
Low size and weight, low power consumption
Adjustable pollution threshold to filter out minor detection events
Remote access to setup operational parameters
Operates as a stand-alone or network unit
