Description

Introduction

 

Universal Digital Ratemeters (UDR) are radiation monitoring instruments capable of being directly interfaced to pulse producing or low current producing detectors and displaying the radiation signal in various engineering units; (CPM, mR/h or µCi/cc). The UDRs are also capable of being interfaced to a computer system, via the digital communications port, and can be used as a local controller. Designed using military specification components, Fluke Biomedical’s family of UDRs achieves a high degree of reliability and are qualified for use in nuclear safety related applications. Thousands of UDRs have been installed around the world.

 

  • For use as area or process monitor readout
  • Compatible versions for all GM, ion chamber or scintillation detectors
  • High visibility LED display and status indicators
  • Analog outputs for recorder, remote display and computer
  • Fail safe DPDT relay contact outputs for warn, high and fail functions
  • Full seismic, environmental and EMI qualifications

 

 

 

Key Features

  • User adjustable alarm set-points; retained indefinitely on power outage, keylock protection available
  • Front panel pushbuttons for check source activation, high voltage indication, alarm setpoint indication, alarm acknowledge, and power ON/OFF
  • Small front panel size allows dedicated display for each channel while minimizing panel space
  • Ability to use existing cables when replacing most analog readouts
  • Plug-in connectors for field connections
  • Remote alarm acknowledge capability
  • Available with international units display
  • Ability to interface with "smart detectors"
  • Optional ribbon cable output adapter

 

 

Applications
The Model 942A-200 UDR can be used with all Model 943 Series Beta and Gamma Scintillation Detectors. The detector, when connected to the UDR, will comprise a single channel digital process monitoring channel. The Model 946A-200 UDR can be used with all Model 977 Series Wide Range Ion Chamber Detectors. The Model 956A-201 can be used with all Model 897A Series GM Detectors. Simulators are available for all models.

 

 

Specifications
The Universal Digital Ratemeters (UDR) feature a bright LED digital display and tricolor LED bar graph, both of which are easily read from a distance of 20 feet. The bar graph changes color with changes in alarm status, providing instantaneous recognition of relative levels and alarm status
