Pressure Chart Recorders

A pressure chart recorder is an instrument that continuously monitors and records pressure levels over time onto a circular chart. This provides a visual representation of pressure fluctuations, aiding in system diagnostics and compliance documentation.

Pressure recorders utilize sensors to detect pressure changes. These changes move a pen across a rotating chart, creating a continuous trace that reflects pressure variations over a set period, such as 24 hours or 7 days.

Setup: Install the recorder at the desired monitoring point, ensuring a secure connection to the pressure source.

Chart Installation: Place a new chart on the device, aligning it with the current time.

Operation: Activate the recorder to begin monitoring.

Reading: After the recording period, remove the chart. The pen’s trace indicates pressure levels over time, with the chart’s time markings helping to correlate pressure changes to specific intervals.

Pressure Range: Ensure the device can measure the expected pressure levels in your application. Select an appropriate option for pressures ranging from 100-1000 PSI.

Chart Size and Duration: Select appropriate chart dimensions and recording durations (e.g., 24-hour or 7-day) based on monitoring needs. For more detailed resolution, shorter time frames are suggested.

Durability: Opt for recorders with robust enclosures, especially for harsh environments. Dickson pressure chart recorders feature a rugged black ABS case, polycarbonate door, and aluminum dials.

Power Source: Decide between battery-operated or externally powered units based on portability and installation constraints.

Accuracy varies by model. For instance, Dickson’s 8-inch pressure chart recorders offer a resolution of .1.

Dickson offers chart recorders for temperature and humidity, as well as models that monitor pressure separately. Dickson does not provide a chart recorder that simultaneously monitors temp/humidity and pressure. 

Dickson’s pressure chart recorders cover various ranges, including 0-100 PSI, 0-200 PSI, 0-300 PSI, and up to 0-1000 PSI, catering to diverse monitoring requirements.

Calibration involves comparing the recorder’s readings against a known standard and adjusting as necessary. It’s recommended that Dickson calibration services be utilized for yearly or bi-yearly adjustments depending on your standard operating procedures.

Many pressure chart recorders are designed for high-pressure applications. For instance, Dickson’s 8-inch pressure chart recorders are built to withstand demanding conditions up to 1000 PSI.

With proper maintenance and calibration, pressure chart recorders can function effectively for many years. Regular calibration and timely replacement of consumables, like pens and charts, are essential for longevity.

Many pressure chart recorders are battery-operated, offering portability and ease of installation without the need for external power sources. For example, Dickson’s 4-inch pressure chart recorders operate on a single AA battery. The 8-inch model utilizes an AC adapter.

Regular Calibration: Schedule periodic calibrations to maintain accuracy.

Routine Maintenance: Inspect the device for wear, replace consumables like pens and charts, and check battery levels.

Performance Checks: Compare recorded data against known standards to verify functionality.
