Kitchen Exhaust Oil particle sensor

Hi All,

I am trying to locate a sensor for the following application:


I require a sensor for installation in a kitchen exhaust duct. The sensor is required to measure airborne oil and grease particles that are located in the exhaust air stream.

The sensor will be permanently located in the kitchen exhaust duct, thus constantly exposed to high temperature exhaust (up to 400 C) under normal operating conditions.

Grease particles can be broken down into two size categories: grease smoke particles ranging from 0.03 to 0.5 microns, grease steam particles (grease-covered moisture particles) ranging from 0.5 to 6.0 microns

The preferred output from the sensor will be 4-20mA, connected to an existing system.

Anticipate logging a read ~ every 4 hours

Any help/direction would be greatly appreciated.

Cheers
