Automation Products Group Inc. (APG)
About
Automation Products Group, Inc. (APG) designs and manufactures level, pressure, and measurement sensors at its ISO 9001:2015 certified facility in Logan, Utah, with over 40 years of sensor innovation dating to the 1970s. The company's flagship TRUE ECHO radar series uses 76-81 GHz FMCW technology delivering plus-or-minus 3 mm accuracy, with the TRUE ECHO CR-L providing non-contact liquid level measurement and the TRUE ECHO Plus combining radar with a submersible pressure transducer for dual-sensor overfill and flood detection in lift stations and wet wells. The ultrasonic level sensor line spans 12 models from short-range (IRU-5000 at 79 inches) to long-range (IRU-3430), including the intrinsically safe LPU-2428, loop-powered LPU-2127, pump control DST, web-enabled LOE with Modbus, and intrinsically safe Modbus MNU-IS. Magnetostrictive sensors include the explosion-proof MPX-E and PVDF-lined MPI-F for harsh chemical service. Submersible pressure transducers range from the general-purpose PT-500 to the PT-503 with PVDF wetted parts for corrosive wastewater and the intrinsically safe PT-400. The Settler and Explorer remote monitoring gateways provide cellular and WiFi connectivity for unattended lift stations, wells, and storage tanks. APG offers NIST-traceable in-house calibration, 24-month warranties, and standard 2-4 week lead times.
