Many environmental conditions can be tough on a sensor. High vibrations, dirt, water, caustic chemicals, temperature extremes, flammable vapors, and intense pressure can push a sensor to its limit. In these situations, reliability isn’t optional, it’s essential. At Automation Products Group, Inc. (APG), we provide such sensors right where you need them. Our sensors are built with proven materials, engineered housings, and certified quality standards so you can count on accurate, dependable data for years to come.
Materials Matter
A sensor is only as good as the materials it’s made from. At APG, we craft each of our sensors for their individual applications. We offer the following materials for the best performance:
- 316L Stainless Steel—highly versatile, great for non-corrosive substances such as diesel fuel.
- Titanium—perfect for saltwater and marine environments, resistant to higher temperature conditions.
- Polyvinylidene Fluoride (PVDF)—chemically resistant material for challenging applications involving aggressive chemicals.
- Polyurethane—suitable for harsh liquid environments and resistant to material build-up and fouling.
A sensor’s housing is also important. Well-constructed housing protects the valuable electronics inside from damage.
Waterproof sensor housing is critical for certain sensor applications, such as the water and wastewater industries. IP68 housing can help your sensor withstand pressure from water jets and even up to full submersion in water.
Dirt and dust can build up on electrical connections or even creep their way into circuit boards. IP67 housing protection can keep your sensor safe from dirty, dusty environments as well as moisture-filled locations.
NEMA ratings provide additional safeguards, including resistance to oils, coolants, and ice forming on the sensor housing.
Chemical interactions can degrade certain materials, so it’s important to understand the compatibility with your sensor and what it’s exposed to. We have a Chemical Compatibility chart to help you determine what chemicals can safely interact with the materials of your sensor.
Quality You Can Trust
Durability isn’t just about materials; it’s also about quality assurance at every step. APG maintains rigorous quality control with both internal and external audits several times per year, ensuring every sensor meets our exacting standards.
- CSA Certifications: Every CSA-certified product undergoes extensive testing to confirm it meets safety and performance requirements for North America.
- Explosion Proof and Intrinsically Safe Sensors: ATEX and IECEx certifications ensure that sensors used in hazardous locations won’t introduce additional risk. These internationally recognized standards means your equipment is safe, compliant, and ready for global operations.
- ISO 9001:2025 Certification: Our facility is ISO-certified, meaning we continuously meet and exceed international standards for quality management. Annual surveillance audits keep us accountable and consistent.
Built for Your Industry
Whether you’re working in water treatment, chemical processing, manufacturing, or hazardous environments, you need sensors you can trust. APG sensors are designed to perform under pressure.
