DP7600-A05 High Speed Load/Strain Meter & Process/Voltmeters
High Speed Load/Strain Meters and Process/Voltmeters, Dual Differential Inputs Available
Supported Applications
The Omega DP-7600 Series functions as a high-speed, high-resolution strain gauge readout designed for dynamic measurement tasks. The series supports applications requiring rapid data acquisition and limit monitoring, performing up to 1000 conversions per second with 15 bits (plus sign) resolution.
Documented operational capabilities include:
• High-speed strain gauge readout
• Limit checking at user-selectable rates from 1 - 500Hz
• Peak and runout tracking
• Tare readings of up to 50% of span
A specific warning states that these products are not designed for use in, and should not be used for, human applications.
Operating Conditions & Performance
The DP-7600 Series delivers a conversion rate of 1000 conversions per second. The display provides a stable 1Hz filtered data reading while internal processing handles limit checking and peak/runout tracking at selectable rates between 1 - 500Hz.
Key performance characteristics include:
• Resolution: 15 bits (plus sign)
• Tare Capability: Up to 50% of span
• Data Modes: Absolute and relative reading modes allow the tare feature to be enabled or disabled without losing the stored value.
Status indicators for limit status and display mode settings are provided via front panel LEDs. Calibration is protected by a security code to prevent unwanted corruption of calibration data.
Voltage/Current Metering (DP7700)
While the primary documentation focuses on strain gauge readout, the series bundle includes variants designated as DP7700 models. These units are categorized under voltage and current measurement configurations within the same product family.
Configuration Options
The DP-7600 Series offers configurable options for power supply voltages, communication interfaces, and display features across its enumerated variants.
• Power Supply Options: Variants support 115 VAC, 9 to 18 VDC, 230 VAC (specifically on DP7700-A10-230VAC), and 18 to 36 VDC.
• Communication Interfaces: Remote interfacing is available via RS232/RS485 (optional) or active low logic inputs located on the rear of the unit.
• Display & Control Features: Models include options for peak/runout display control, dual-channel configurations (e.g., DP7700-DUAL-S2), and specific suffix codes indicating feature sets such as -A05, -A10, -AMA, -R, and -S2.
User programming is performed using five front panel switches. The unit allows for the entry of a tare reading with a single switch press.
Model Number Guide
The series utilizes specific suffixes to denote configuration differences:
• -A05, -A10: Specific variant configurations available on both DP7600 and DP7700 models.
• -AMA: Available as a distinct option code (e.g., DP7600-AMA).
• -R: Indicates specific model variations (e.g., DP7600-R, DP7700-R).
• -S2, -DUAL-S4: Denotes display or channel configurations such as dual-channel operation.
Key Product Differences
The series distinguishes between the Model DP-7600 strain gauge readout and the DP7700 voltage/current metering models. While both share the high-speed architecture, their primary measurement types differ as indicated by their model families.
• DP7600 Models: Configured primarily for strain gauge applications with features like peak/runout tracking and limit checking at 1 - 500Hz.
• DP7700 Models: Listed under voltage/current measurement families, offering similar high-speed performance but tailored for electrical signal monitoring. Variants include dual-channel options (e.g., DP7700-DUAL-S2) and specific DC power ranges not present in the standard AC strain models.
The series holds ISO 9001 Certified and ISO 9002 Certified approvals as noted in the documentation. Specific physical dimensions, enclosure ratings, and environmental limits are not specified in the provided source data.
