چکیده
It records one or more variables with respect to time. It is a X-t recorder. A strip chart recorder consists of: 1. A long roll of graph paper moving vertically. 2. A system for driving a paper at some selected speed. A speed selector switch is generally provided. Chart speed of 1-100 m/s are usually used. 3. A stylus driving system which moves the stylus in a near exact replica or analog of the quantity being recorded. A range selector switch is used so that input to the recorder drive system is with in the acceptable level. A. Paper drive system: The paper system should move the paper at a uniform speed. A spring would may be used but in most of the recorder a synchronous motor is used for driving the paper. B. Marking Mechanism: There are many types of mechanism used for making marks on the paper. The most commonly used ones are:

متن کاملSimple Timing Device Increases Reliability of Recording Telemetric Activity Data
Many wildlife biologists still rely on strip-chart recorders for collecting telemetry information in the field, and modifications that improve the reliability of recording telemetric data and reduce the time required to analyze these data are needed. We observed that 2 identical recorders, which had been geared to run at the same chart speed (5.08 cm/hour), operated at different speeds (4.32 cm...
متن کاملContinuous-recording flame photometry of sodium and potassium in serum.
Serum sodium and potassium analyses by continuous-flow flame photometry is a well-accepted procedure (1, 2). Recently Habig and Williamson (3) have used the widely available Instrumentation Laboratory Model 143 (IL-143) flame photometer for continuousflow analyses. Pennacchia et al. (4) have operated this flame photometer at rates as high as 120 samples per hour. In both systems the results app...
متن کاملA simple calf muscle ergometer for use in a standard whole-body MR scanner.
A calf muscle ergometer, designed for use in a standard whole-body MR scanner, is described. The instrument allows isotonic or isometric calf muscle exercise over a continuous range of work loads from 0 to individual maximum work output. Work output may be recorded on a strip chart recorder. A sound encoding provides an effective guidance for the subject tested to accurately reproduce his perfo...
متن کاملA home monitoring system for nasal CPAP.
A compact portable sensing system (PSS) was developed for home monitoring of patients with obstructive sleep apnea treated with nasal continuous positive-airway pressure (CPAP). The system consisted of a solid-state pressure sensor connected with plastic tubing to the side port of the nasal CPAP mask, a power supply, and a strip chart recorder. The device was validated against standard polysomn...
