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
