APG Instrumentation

Industrial pressure and level measurement instruments including a submersible level sensor with probe cage, a digital pressure gauge with LCD display, and an ultrasonic level transmitter used for monitoring liquid levels and pressure in tanks and process systems.

APG (Automation Products Group) instrumentation is designed to deliver reliable measurement of level, pressure, and distance in demanding industrial environments. RSP Supply offers a range of APG sensors used in automation, process control, and monitoring systems where accurate data and long-term durability are essential. These instruments are commonly applied in industries such as water and wastewater, chemical processing, oil and gas, food production, and general manufacturing, where dependable sensing solutions are required for consistent operation.

APG is widely recognized for its level measurement technologies, including ultrasonic, radar, and submersible pressure sensors. These devices are used to monitor liquid levels in tanks, wells, sumps, and bulk storage environments, including applications involving challenging materials such as slurries or viscous fluids. In addition to level sensing, APG offers pressure transmitters and ultrasonic distance sensors for object detection and position measurement. Their products are designed for straightforward installation, stable signal performance, and minimal maintenance, making them suitable for long-term use in industrial systems.

APG instrumentation supports integration with common industrial control systems through standard output signals such as 4–20 mA and digital communication protocols. These sensors are widely used in SCADA systems, PLC-based automation, and remote monitoring applications where accurate and timely data is critical. With a focus on durability and measurement reliability, APG products help support efficient process control and system performance across a wide range of industrial environments.
