What is a paperless chart recorder?

A paperless recorder is a data logger or data acquisition device used to record measurement data over time. A paperless recorder can feature an internal memory allowing for stored data to be transferred to a PC via a USB stick or flash drive.

How does a paperless recorder work?

Paperless recorder is a device that records the collected calculation data in the internal storage system of the instrument based on time. The stored data recorded in the instrument is displayed on the LCD screen after calculation and simulation.

What is potentiometric pen recorder?

Potentiometric recorders compare the input signal with a reference which results in an error signal which is amplified thus driving the pen motor. Potentiometric recorders typically have a fast response , smaller bandwidth, very high input impedance, and high sensitivity.

What is circular chart recorder?

Circular chart recorders are data acquisition tools that archive data points onto a uniformly rotating circular chart over a timed interval in proportion to the signal received. The charts usually rotate over standard time periods (e.g. 24 hours, one week, one month, etc.)

What is a chart recorder that measures and records temperature?

thermo-hygrograph
A thermo-hygrograph or hygrothermograph is a chart recorder that measures and records both temperature and humidity (or dew point). Similar devices that record only one parameter are a thermograph for temperature and hygrograph for humidity.

What are the main parts of potentiometric recorder?

Potentiometric recorder block diagram The potentiometer is supplied with a reference voltage derived from an internal power supply. The output of the internal power supply is made stable. The field coil of the motor is energized by the output of the amplifier. The output of the amplifier is the error signal.

What is the type of XY recorder?

Nearly all X-Y recorders are potentiometric servo types, with separate input networks and amplifiers for the two axes. Hence the chief differences from the instruments discussed in Chapter 3 are in mechanical rather than electrical features.

What is a XY recorder?

By the term X-Y recorder is meant an instrument that is capable of plotting any two variables against each other, rather than against time. Nearly all X-Y recorders are potentiometric servo types, with separate input networks and amplifiers for the two axes.

What is a temperature chart recorder?

Temperature Chart Recorder, Portable (Liquid Sensor) Key-Wound Temperature Chart Recorders are equipped with liquid or air sensors, offer selectable 24-hour or 7-day operation and recording, and have a temperature range of 0°—150°F.

Is there a paperless chart recorder from Grainger?

Chartless Digital Recorders. A digital paperless chart recorder from Grainger can provide a simple yet powerful, low-maintenance method of data reporting. No time is spent changing paper or pens, and a digital paperless recorder requires less time to calibrate.

What are paperless recorders and how are they used?

Paperless recorders are fully integrated data acquisition and display stations with secure, built-in data storage and network connectivity. Yokogawa offers a range of paperless recorders including panel mount and portable type recorders.

Which is the best paperless recorder for thermocouple?

The RD8900 Series paperless recorders offers real time display of data for thermocouple, RTD, or Process inputs on a color display. Optional Ethernet, RS-232/422/485. The RDA Series is a low cost paperless recorder with multiple screen sizes and inputs to support either thermocouple or RTD inputs.

What kind of inputs are in Omega paperless recorders?

The RD8250 Series paperless recorders offers 2 configurable inputs for DC current/voltage, thermocouples, RTD, frequency, and pulse. It also has internal alarms and relays. RD9900 Series paperless recorders are network compatible with a color display for 6 or 12 thermocouple, RTD, or process inputs.
