Filter Humidity Temperature Sensors SHT1x
Protection against dust other contaminants Water proof, IP67 protection class Easy mounting sensor into housing
Filter Product Summary
Filter provides IP67 protection against water, dust other contaminants humidity temperature sensors SHT11 SHT15. cost part very easy use. Filter consists single piece polypropylene including filter membrane. fits outer dimensions SHT1x sensors allows compact system design. also serves adaptor mounting sensor directly into wall housing. Using sealing ring, this results waterproof mounting solution. Preliminary Information

Application Information
Using Filter Cap, separation made between environment, which relative humidity measured readout electronics. Such separation needed mainly areas with dust particles air: HVAC applications, where large volumes airflow passing sensor, appliances (e.g. lints garment dryers) agricultural environments, where dust dirt present. Furthermore, consistent reliable humidity measurements enabled protection against water immersion. Another important issue addressed Filter mount sensor housing. provides simple, easy-toapply possibility mount sensor e.g. HVAC transmitters, data loggers, ducts etc. filter membrane allows waterproof mounting water column when sealing ring used addition.
Mounting Information
There three possibilities mount through hole Filter Cap: Fixed between housing wall small pressure Glued and/or housing wall (recommended: epoxy resin based glue, e.g. Epoxy Loctite EE8016F-EB0363) pins Filter heated least 160°C with heating tool melt form robust fastening.
