Product Details:

FOXBORO 740RA-A3333-N is a 740 series circular chart recorder, a reliable data logger built for process automation. This circular chart recorder adopts a robust metal enclosure with a round chart mechanism, designed for panel mounting in control rooms and field operating stations. The mechanical and electronic assembly is well protected against dust, vibration and moderate humidity, ensuring stable continuous recording in industrial environments. It can accept multiple types of input signals from field sensors, continuously record and display process variables for long-term trend tracking and production audit.

This FOXBORO 740RA-A3333-N data logger receives input signals such as DC current, DC voltage, thermocouple and RTD signals from temperature, pressure, flow and liquid level transmitters. It records process data on circular chart paper, showing real-time trend curves for operators to view historical and current process status directly on site. The recorder supports multi-channel signal input, which can monitor multiple process variables simultaneously. It has built-in signal conditioning and calibration functions to maintain measurement accuracy. The device integrates fault detection to identify signal loss or mechanism abnormality and alert operators, helping avoid missing critical process records.
