The Istec RecipSys 200 is a compact, transmitter-based monitoring system engineered specifically for real-time measurement of rider band wear in reciprocating compressors. By providing continuous data on rod position and drop, it eliminates the need for periodic production shutdowns for manual inspections, significantly reducing downtime and maintenance costs . The system is designed to have a low technical and financial impact, making it suitable for a wide range of compressors .

The system features two channels for rod displacement monitoring using 3-wire eddy current sensors, which are industry-standard and compatible with any brand, allowing for easy integration into existing monitoring setups. It also includes one Tacho (phase trigger) input. The measurement range is 0 to -24 Vdc, and it provides its own -24 Vdc power supply for the sensors. The system filters the displacement signal to the correct phase angle, ensuring reliable measurements for compressors operating at both fixed and variable speeds. A triggered signal method enhances accuracy compared to overall measurements .

Outputs include two industry-standard 4-20 mA analog outputs for straightforward integration with PLCs, DCS, or other monitoring suites. It also provides two raw signal outputs, one trigger signal, and three relay outputs for alarms and status indication. The RecipSys 200 is designed in accordance with the API 670 industrial standard, ensuring reliability and performance in demanding environments . Its expandable architecture can accommodate any cylinder configuration, making it a versatile solution for reciprocating compressor protection.
