Doric 5000T Digital Temperature Indicator and Miniature Datalogger

Programmable Digital Temperature Indicator and Data Logger

The Doric 5000 Series of single and multiple channel digital temperature indicators sets a new standard for performance, features, value and reliability. With built-in programmability, RS232 serial communications and powerful Windows-based software, the Doric 5000 is ideal for monitoring, testing and process control applications.

Complete configuration of the instrument can be quickly performed from the front panel, including sensor input type, sampling rate, limit settings, and resolution. Current value and min/max values can be selected for display from the front panel.

Thanks to its exclusive Viewer software, the Doric 5000 becomes a powerful PC-based data gathering, display and logging system. All front panel setup commands can be executed from your PC and all channel data, limit/alarm status and min/max values can be viewed simultaneously. In addition, you can label channel data, perform engineering unit calculations, log data and create exportable data files.

With the multiple inputs option installed, the 5000 Series provides simultaneous monitoring of up to six thermocouple or three RTD channels.

On single input models, an optional board may be installed which provides enhanced alarm functions as well as a scalable, linearized 4-20ma/0-10V analog output.

Multiple Inputs

Instead of the dual alarm/analog output option, the Doric 5000 can be configured to accept up to six thermocouples or three platinum RTDs.

All active inputs can be manually selected or automatically scanned. A front panel channel indicator accompanies the displayed data. Individual limits can be assigned to each channel. A built-in 5A rated form-C relay is energized whenever the limit on the selected channel is exceeded.

Analog Output

Analog output capability is also available in combination with the dual alarm option. A linearized output (4-20mA or 0-10V) with fully adjustable zero and span allows the instrument to serve as an indicating transmitter for a proportional controller, high-level input to a PC-based data converter or other recording device.

Dual Alarms

With the dual alarm option installed, the Doric 5000 can be configured to perform on/off control functions as well as process monitoring. Setpoints can be set for high, low or deviation. In addition, hysteresis (deadband) and delay can be programmed into each setpoint. Alarm conditions can be programmed for manual acknowledgment or for automatic reset. The dual alarm option comes equipped with two 5A rated form-C (NO/NC) relays, one for each alarm setpoint and flashing display whenever an alarm condition exists.
