The story of APG begins with the journey of a Utah State University graduate who utilized his engineering skills to bring about a positive impact in the lives of farmers. Cordell Lundahl, armed with his knowledge and expertise, set out to address a common challenge faced by farmers—maneuvering farm machinery around the uncut edges of fields. His solution was the design of an ultrasonic sensor and control system that could guide farm machinery along these edges. As time progressed, APG continued to evolve and expand its product offerings. Over the course of 40 years, the company diversified its portfolio to include a comprehensive range of level sensors and switches, pressure transducers, and data management tools. These solutions were designed not only to benefit farmers but also to cater to the needs of various industries and professionals. Through its continuous commitment to technological innovation and product development, APG established itself as a trusted provider of solutions that empower individuals and industries to better control their processes and inventories. The company's humble beginnings, rooted in the dedication of an engineering graduate to improve the lives of farmers, eventually blossomed into a comprehensive range of offerings that cater to the diverse needs of professionals for many level and pressure applications. The current product line consists of ultrasonic level sensors, radar level transmitters, continuous float level transmitters, submersible pressure transducers, pressure transducers, hammer union pressure transducers, digital pressure gauges, level switches, float switches, displays and controllers, aviation and aerospace products.
