Circular Chart Temperature Recorders
Aerospace
Temperature recording with circular chart recorders from Palmer Instruments, Inc. Temperature chart recorders have ranges from -40°C to 537°C in both 8 inch and 12 inch sizes. Recorder accuracy is ±1 chart division. Temperature recorder uses circular charts for temperature logging in a rugged housing designed for outdoor use.
Key Features
Palmer Recorders are available in 8″ or 12″ models, and come complete with either electric, spring wound, or PC-11 (battery operated) chart drive, and up to three (3) felt tip pens. Case mountings are wall, flush, pedestal, pipestand or portable. The combinations of case mounts and internals allow selections which meet your specific requirements without limiting performance or demanding a custom price.
Pressure & Temperature Recorders
- Temperature and pressure can be combined inside the same recorder with up to three (3) pens.
Temperature Recorders
Temperature ranges from -40°C to 537°C in both 8″ and 12″ recorders. Recorder accuracy is ± 1 chart graduation.
Temperature Elements
- Palmer’s temperature recorder elements must pass stringent quality control. All filled systems conform to ASME and other designations such as 5A or 5B. Each system is pressurized after filling so it will have overrange capabilities above and below its specified range. Rapid response to changes in temperature makes it extremely accurate and reliable. The system is completely welded to prevent deterioration. Points most susceptible to physical damage are reinforced with added flexible armour.
