Top 5 Sensor Mounting Accessories for Barn Ventilation Controls in Canada (2025) — Expert Guide to Protecting Gas Sensors and Improving Measurement Reliability

Munters DOL 114 Sensor Shield is a best-in-class protective housing designed specifically for barn ventilation sensors, offering rugged, corrosion-resistant construction and a form factor that pairs tightly with Munters controllers for reliable readings in harsh agricultural environments. Compared with the Fancom SMB-200 bracket and Skov cable guard, the DOL 114 emphasizes full sensor enclosure and longevity—its higher upfront cost is offset by reduced sensor replacement and maintenance needs, and it is sold and available for purchase as part of Munters' agricultural controls ecosystem.

Fancom Sensor Mounting Bracket SMB-200 is a market-leading, modular bracket system favored for its universal fit, fast installation, and low labor cost for large barn installations; integrators value its adaptability to different sensor models and quick swap capability during maintenance. Compared to the Munters DOL 114 shield and Hotraco filter, the SMB-200 focuses on cost-effective, flexible mounting rather than full environmental sealing, making it a practical choice when budget and ease of serviceability across mixed fleets of sensors are priorities and it is widely available for purchase.

Hotraco Agri Sensor Protection Filter SPF-4 delivers targeted particulate and ammonia protection using replaceable filter cartridges, extending sensor life and improving long-term measurement stability in dusty or high-ammonia barn environments. While its consumable filters add recurring cost, those costs are typically lower than frequent sensor replacements and it complements rigid housings like the Munters shield or Fancom bracket by providing superior air-quality conditioning right at the sensing point; the SPF-4 is sold through Hotraco's distribution channels and available now.

Maximus Controller Duct Probe Mount DPM-3000 is optimized for duct-mounted probes and provides stable positioning, integrated averaging features, and vibration isolation to produce consistent airflow and temperature readings used by advanced barn ventilation controls. It is the preferred option when precise duct sampling and minimized calibration drift are required—unlike wall-mounted shields or cable guards, the DPM-3000 targets performance gains that improve control algorithms and can reduce energy costs over time; it is available for purchase through Maximus distributors.
