| Ludlum Model 375 Series Radiation Area Monitors. |
FEATURES:INTRODUCTION:
The Model 375 is a versatile, compact and very affordable digital electronic controller designed for monitoring
radiation in areas. Its simple design accommodates many different detectors suiting a wide variety of applications and
is equipped with a local readout and alarms. These versatile units may also be connected to an optional auxiliary
indicator/annunciators for alerting personnel at remote locations. The user-friendly, digital design enhances setup and
operation. These units may also be networked to a central PC-based station where data are logged and alarms posted.

ETHERNET OPTION: Enables the Model 375 Digital Controller to be connected to an Ethernet Network. If ordering
this option, please download and complete
the Model 375 Network Setting Request Form and submit it with your order so the instrument can be properly
configured at Ludlum's factory to facilitate your network system. CAMERA OPTION: An industrial camera that delivers high speed IP video, enhanced low-light performance, and 1280 x 1024 resolution. This can be used to capture a picture of what triggers an alarm using the Ethernet Software Application. |  |

ETHERNET HARDWARE PORT OPTION GENERAL: The Model 375 Ethernet sofware monitors and stores data from up to 50 Ethernet-enabled Model 375s. Instrument readings and status are displayed on the main screen. Ethernet cameras (optional) can capture a picture of what triggers the alarm. This program is relatively easy to setup and ideal for straightforward networks not involving any routers. COMMUNICATION: Uses User Datagram Protocol (UDP) for basic communications on Local Area Network (LAN). The UDP port is user configurable from 50000 to 59999. DISPLAY: The main window displays reading boxes for all 50 Model 375s along with their status, units and caption. Clicking on the channel name will display the last image and alarm information that has occurred since the program was running. Holding the mouse over the channel name will display a tool tip with the user-defined comment. DATA LOGGING: Data is logged to a Microsoft Access® database and also a comma-delimited file. The rate at which the data is logged is user-defined and data can be logged at a different rate when an alarm occurs, which allows more data to be collected during the alarm. Readings are sent from the Model 375 every two seconds. An indicator bar under each reading changes color to indicate the current status of the monitor. ALARM IMAGE WINDOW: When a high alarm occurs the image will be retrieved from the camera and displayed in a resizable window along with the date, channel caption and reading. The images are saved in the images folder under the installation path. QUICK ALERT WINDOW: When a failure or alarm occurs, a window is displayed showing the channel, date, reading and type of event. This data is available until the window is closed. E-MAIL SETTINGS TAB: The E-mail Setting tab allows the configuration of the e-mail capability of the software. Four sets of nine e-mail addresses are available separated by day/night and alarms/other events. GRAPH VIEW WINDOW: The Graph view displays the readings from the Model 375 as a graph with options to view live or previously saved data (archive mode). | Whoops - missing graphic file |
