Description
JI-CCR-MT-S Mechanical Motor / Spring-Wound Single Pen Circular Chart Recorder
The “Ji” Japsin Instrumentation JI-CCR-MT-S Mechanical Motor / Spring-Wound Single Pen Circular Chart Recorder is designed for recording pressure or temperature variations over time in industrial monitoring, testing, and process documentation applications. Featuring a single-pen recording arrangement and a mechanical chart-drive system, this recorder provides a graphical record of changing process conditions that can be reviewed for analysis, inspection, and quality-control purposes.
Unlike a conventional pressure or temperature gauge that displays only the current measurement, a circular chart recorder creates a time-based record of changing values. This helps operators and engineers understand how a process behaves during a test or operating cycle, identify fluctuations, and maintain physical records for future reference.
The JI-CCR-MT-S is intended for applications using compatible Bourdon tube or gas-filled sensing arrangements, depending on the selected instrument configuration. Its mechanical motor or spring-wound drive provides chart movement without necessarily requiring an electronic chart-drive system. The exact drive arrangement and sensing configuration should be confirmed when selecting the model.
Mechanical Motor and Spring-Wound Chart Drive
The recorder uses a mechanical chart-drive arrangement intended to advance the circular chart over a defined recording period. In a spring-wound mechanism, stored mechanical energy drives the chart movement after the mechanism has been wound according to the manufacturer’s instructions.
This design can be useful in applications where a mechanically driven chart recorder is preferred. It also allows the recording process to be considered independently from the electrical requirements of electronic recording systems, although the complete instrument configuration should be checked for any additional power needs.
The chart rotation time, winding interval, and recording duration depend on the mechanism supplied. These details should be verified before purchase to ensure that the recorder meets the required monitoring period.
Single-Pen Circular Chart Recording
The JI-CCR-MT-S uses a single-pen configuration to record one measurement channel on a circular chart. As the measured pressure or temperature changes, the sensing mechanism moves the recording pen, producing a trace that represents the measurement over time.
This graphical record can help users review operating trends, observe fluctuations, and identify unusual changes during testing or production. A completed chart can also be retained as part of maintenance documentation, inspection records, or quality-control files.
The single-pen arrangement is particularly suitable when one process variable needs to be monitored and documented without the complexity of a multi-pen recording system.
Bourdon Tube Pressure Recording
For compatible pressure-measurement configurations, the recorder can use a Bourdon tube sensing mechanism. When pressure is applied to the curved elastic tube, it deforms slightly. The resulting mechanical movement is transferred through a linkage to operate the recording pen.
As pressure changes, the pen position changes accordingly, creating a graphical record on the circular chart. This makes the instrument useful for pressure testing, industrial process monitoring, and applications where a historical record of pressure behaviour is required.
The appropriate pressure range, process connection, and wetted materials must be selected according to the process conditions and the specific instrument configuration.
Gas-Filled Temperature Recording
The product description also identifies gas-filled operation for suitable configurations. Gas-filled temperature-measuring systems generally use a temperature-sensitive bulb connected to a pressure-responsive measuring mechanism through a capillary system.
As the bulb temperature changes, the sensing system responds and transfers movement to the recording mechanism. This can enable the instrument to record temperature variations over time, subject to the design and configuration of the supplied model.
The sensing system and chart recorder must be selected for the intended temperature range, installation arrangement, and environmental conditions. Confirm whether the required gas-filled temperature configuration is available for the exact JI-CCR-MT-S model.
Reliable Process Documentation
The circular chart format provides a physical record that can be reviewed after a measurement period. It can help users evaluate pressure or temperature trends, investigate process deviations, compare operating cycles, and maintain records for inspection.
Mechanical recording is useful in applications where a paper chart is preferred for documentation. For dependable results, the instrument should be installed correctly, operated within its specified limits, and maintained according to the manufacturer’s instructions.

Installation and Operating Considerations
Before ordering, confirm whether the intended application requires pressure recording through a Bourdon tube or temperature recording through a gas-filled sensing system. Verify the measurement range, connection arrangement, sensing element, chart dimensions, and recording duration for the selected configuration.
For spring-wound versions, follow the manufacturer’s instructions for winding and chart replacement. For pressure applications, ensure that the complete sensing assembly and connections are rated for the operating conditions. For temperature applications, confirm the suitability of the bulb, capillary, and measuring system for the installation environment.
Calibration and maintenance should follow the manufacturer’s recommendations, especially where recorded data is used for quality-control or process verification.
