Intrinsically Safe Sensor for Spray Dryer

It starts with a list of solvents, please.

What temperature do things start to burn at? Are you talking about the heaters causing something to burn or the heaters themselves burning out? Obviously, I am confused.

A standard commercial smoke detector can be used if connected to the control equipment using intrinsically safe barriers. An ionization type would be better than a photoelectric type here. An alternative would be a laser detector with sampling tubing such as a VESDA system (google it). This type of system would be pricier.

You can't just use a commercial smoke detector unless it's rated for the area, regardless of what it's connected to. Just to clarify, when using an intrinsically safe barrier between a controller and a sensor, the entity parameters on the barrier and sensor have to match, so the sensor itself has to be intrinsically safe.

Consider using a Combustible Gas Detector available from a number of manufacturers. These come in both explosion-proof and intrinsically safe versions.

Yes, it goes without saying that the device parameters must match and the devices must be suitable for the areas. Commercial smoke detectors are available for standard, harsh (dirty, dusty, humid), and explosionproof environments.

Combustible Gas Detectors are designed to measure the presence of Combustible Gases (Methane, Hydrogen, etc). They do NOT measure combustion and cannot be used in this application.
