Absolute Process Instruments

Authorized Absolute Process Instruments Distributor – Signal Isolators, Transmitters & Conditioners

Welcome to RSP Supply, your trusted Absolute Process Instruments (API) distributor. We proudly carry a complete line of API signal isolators, transmitters, conditioners, and amplifiers, designed to deliver accurate, reliable, and cost-effective process measurement solutions for industrial applications.

At RSP Supply, we understand the challenges of maintaining precision and stability in complex process environments. That’s why we partner with Absolute Process Instruments, a leader in industrial signal conditioning and control technology.

Signal Conditioners

API signal conditioners amplify and filter low-level signals from sensors or transducers, ensuring clean, accurate data for process control systems. These devices improve signal quality, accuracy, and reliability, making them essential in manufacturing, automation, and instrumentation environments.

	API signal conditioners are designed to work with a wide range of sensors, including temperature sensors, pressure sensors, flow meters, and level sensors, among others. See our full line of API's Signal Conditioners here.
	API pressure gauges provide durable, accurate pressure monitoring for industrial equipment, offering clear readings and reliable performance in demanding environments. See our full line of API Pressure Gauges here.
	API pressure sensors and transmitters provide accurate, durable pressure measurement for industrial systems by converting pressure changes into reliable electrical signals for precise monitoring and control. See our full line of API Pressure Sensors and Transmitters here.

Signal Transmitters

API signal transmitters convert process variables such as temperature, pressure, flow, and level into standardized analog signals (typically 4–20 mA). This allows for seamless integration into process monitoring and control systems, ensuring consistent, efficient performance across industrial applications.

Signal Isolators

API signal isolators protect sensitive instrumentation from ground loops, electrical noise, and voltage surges. By providing galvanic isolation between circuits, they ensure system integrity, prevent damage, and maintain signal accuracy in critical control systems.

At RSP Supply, we’re committed to helping our customers achieve accurate process measurements and optimized control performance. Whether you operate in manufacturing, energy, or automation, our experts can help you select the right Absolute Process Instruments products for your system.
