Written by Meghan Kelley | March 21, 2019

Setra’s T/RH sensors are built to meet the requirements of demanding applications. The right choice of appropriate filter cap is essential for best long-term performance, and the right sensor tip depends mainly on the application.

Filter	Materials	Applications
Membrane Filter	Body: polycarbonate Filter: PTFE membrane	Superior protection against fine dust Building automation Dusty environment
Stainless Steel Sintered Filter	Sintered stainless steel	For mechanical stress and strong pollution Industrial process control Agriculture Livestock barns Unsuitable for condensing environment
Plastic Grid Filter	Polycarbonate	For applications with no airborne contaminants Mechanical protection only
PTFE Filter Ø12mm	PTFE sintered	For a dirty, oily environment Industrial process control Chemical industry Very polluted environment Unsuitable for condensing environment
Metal Grid Filter	Body: polycarbonate Filter: stainless steel wire mesh	For high RH/condensing environment, low mechanical stress, and low pollution level Climate control Dryers and humidifiers HVAC
H₂O₂ Filter	PTFE sintered	Catalytic filter for H₂O₂ Pharma Biotech HVAC
