Stanford Research SR630 Data Logger 16 chanel thermocouple monitor opt. accy.

Description

Stanford Research SR630
Data Logger 16 Chanel thermocouple monitor
Taken out of working service - Checked for basic operation.
Buttons all function, Display is clear, no bad segments.
Attached one thermocouple to check / show readout.
Includes printer port, RS-232 serial port, and GPIB IEEE488 port.
Case is good, no cracks but some UV fading and sticker staining.
*The last photo shows a breakout box that is currently connected to the input.
It allows easy connection to connectorized probes.
But it's big and clunky and will increase shipping significantly.
*** The shipping quoted is without this box ***
If you want it - let me know and I will get you a new shipping cost - otherwise you will not receive it!
16 channels
0.1 °C resolution
Displays °C, °F, K and VDC
2,000 point memory
Four analog outputs proportional to temperature
GPIB, RS-232 and printer interfaces
The SR630 is a 16-channel thermocouple monitor designed to read, scan, print and log temperatures or voltages. You can use any one of seven standard thermocouple types (not included) to read temperatures from -200 °C to +1700 °C. For remote monitoring applications, the SR630 can time-stamp and store up to 2000 readings in non-volatile memory for later analysis.
Temperature readings from the SR630 can be viewed on the front panel or queried via the instrument's standard RS-232 or GPIB interfaces. In addition, the standard Centronics printer port provides convenient hardcopy output in either tabular or strip-chart format.
Voltage Monitor
The SR630 can also be configured as a 16-channel DC voltmeter with full-scale ranges from 30 mV to 100 V (1 mV resolution). As a voltmeter, the unit has 0.05 % accuracy and 1 µV input offset drift. Each channel can be set independently to monitor either temperature or voltage, giving the SR630 even more flexibility in your application. Four rear-panel outputs are also available to provide a voltage proportional to the temperature of the first four input channels. The voltage outputs can be used to drive recorders or to control external instrumentation.
Inputs
Sixteen screw-terminal inputs are mounted on a rear-panel isothermal block for cold junction compensation. The isolated differential inputs have a 250 V breakdown level, allowing the SR630 to tackle difficult applications such as temperature profiling of electrically live equipment. Each of the 16 channels may be independently set to display in units of °C, °F, K, mV or V. Similarly, thermocouple type, nominal temperature, temperature limit, and alarms may be uniquely set for each channel, providing complete flexibility in the configuration of the instrument. Access to any channel parameter is provided through the front panel or via the computer interfaces. The SR630 can store up to nine instrument configurations including thermocouple type and temperature limits for all 16 channels.
Outputs
There are four analog outputs that are proportional to the readings on channels one through four. Both the slope (m) and offset (b) of the equation, Vout = ±mX + b, are changed by setting the nominal temperature and chart span for the corresponding channel. X is either temperature or voltage, depending on the setting for each channel. You may use the analog outputs to drive chart recorders, or they can provide a feedback signal for proportional temperature control systems. They may also be used as fixed-level, analog control signals (set via the computer interfaces).
Alarms
Each channel can be programmed individually with an upper and lower temperature limit. An audio alarm and a relay closure indicate when any channel exceeds its preset temperature or voltage limits. The front-panel LED display will indicate which channel has exceeded its limit.
Data Logging
An internal, battery backed-up clock/calendar is used to timestamp temperature readings. The SR630 can be set to scan, time-stamp, and record data on up to 16 channels at intervals from 10 to 9999 seconds. Data is either sent immediately to the printer or stored in the internal 2,000 point buffer for output at a later time (via GPIB or RS-232).
Built-In Printer Interface
A standard Centronics printer interface makes it simple to get hardcopy output of temperature or voltage scans. Two hardcopy formats are provided. The SR630 can print a continuous strip chart showing up to 16 different temperatures. In addition, data can be printed in a tabular format which logs the time, date, and temperature or voltage for each channel.
