Product Outline

The LR4100 is a high performance, multipen recorder based on YOKOGAWA‘s long experience with the highly reputed HR and uR series recorders and incorporates the latest technology.

Any DC voltage, thermocouple or RTD input can be selected for each channel. In addition to analog recording, the recorder also allows measured values, dates, scales, alarm Iists, and messages to be printed out or partial suppression-recorded through the use of a wire dot printer. Easy-to-read fluorescent display tubes are used and the recorder is capable of selecting measured data, bar-graph and range data displays for each channel. Thus, while the LR4100 offers high performance, it is easy to operate. Basic items such as range and chart speed can be easily set interactively with the display unit via function keys and setting knobs.

Further, the recorder range of applications can be expanded by adding various optional functions, such as a memory function in the form of an IC card, calculation and GP-IB / RS-232C communication functions, and an alarm output.

Features

¨     Highly Functional and Intelligent

•         Wide range of DC voltage, thermocouple and RTD inputs

          A single LR41OO recorder can cope with all DCV, TC and RTD inputs. Further, lt has cryogenic gold-iron-chromel (KP vs Au7Fe) TC input and a cryogenic platinum and rare cobalt RTD (J263*B) input which are built into it as standard equipment.

•         Versatile print-out functionslncludes (LR4I 10 model only)

          Includes measured data, date, scale markings, alarms, messages, manual prints, lists, etc.

•         A choice of 3 display functions

          Measured data, bar-graph and range data can be selected asrequired.

•         Zone recording (recording area adjustment)

          The recording range can be arbitrarily set by adjusting the penposition.

•         Partial suppression and extension

          The LR4100 can suppress the recording of unnecessary areas and extend the recording of important areas.

•         AUTO Span Shift

          Selecting this mode automatically shifts the recording span by +50%, and continues recording when an input exceeds the measuring range (span).

¨     Computer Friendly

•         GP-IB and RS-232C interfacesBi-directional communication is available in which both interfaces allow data output and panel setting. Further, communication input can be analog-recorded, enabling raw measured data and communication input data to be recorded simultaneously.

¨     Simple Operation

          The LR4100 can be operated as simply as conventional analog recorders, even though it has multifunction capabilities. Using the function keys and setting knobs, various settings are made simply by using an interactive system with the display unit.

•         New Recording Mechanism

          The adoption of new pens allows the recorder to record for about 1500 m (about twice that of conventional units).

          Further, the chart is 30 m long (twice that of conventional charts), enabling continuous operating time to be extended considerably. In addition, the provision of grooves in the platen has almost eliminated ink blots at the chart folding lines, which is a problem at low chart feed speeds in conventional recorders.

•         High-speed Response 1600 mm/s

          Maximum pen speed is 1600 mm/s, significantly improving traceability at high-speed.

•         IC Memory Card

          An IC memory card stores the set values and measured data.

•         MS-DOS format is in common with all other IC memory cards of Yokogawa‘s measuring instruments.

•         Set value memory (standard).

          Previously-used set values can be stored in an IC memory card and used again simply by inserting the IC memory card into the unit.

•         Set value and data memory (optional)

          Can store measured data in which an alarm or external contact is triggered.

          Memory capacity is 256K bytes and the memory can store a maximum of 32,000 data/channel.

          Stored data can be recorded or output for communication as required.

•         AC Universal Power Supply (90 to 250V AC)

•         A Wide Range of Optional Features

•         Mathematical functions (/MATH)

          This function is in addition to the standard difference calculation and scaling functions and is capable of executing various calculations much as arithmetic operations, square root extraction (SQR), absolute value (ABS), common logarithms (LOG) and exponents (EXP). Calculated data can be recorded or output for communication.

•         Remote control function (/REM)

          Chart start/stop, chart speed control, chart speed change, recording ON / 0FF selection, message, and manual print-out are controlled remotely. Selecting recording ON /0FF allows the pens to be raised and lowered independently.

•         Alarm output (/AK-04)

          Four alarm outputs can be obtained and two upper or lower limit alarm levels can be set per channel.

•         DC power supply 10 to 32V DC (/DC)

          This DC power supply allows the recorder to be used in locations without AC power supply - such as in a car or for agriculture use, etc.
