eDAQ Simultaneous High Level Layer

Overview

The SoMat eDAQ Simultaneous High Level Layer (EHLS) offers 16 simultaneously sampled high-level differential analog inputs through independent connectors. Up to four EHLS layers can be added to a single eDAQ system enabling up to 64-channels. Networking multiple eDAQ’s make synchronous EHLS channel counts virtually limitless.

The EHLS can inherently handle any analog input from +/- 80V, and together with the SoMat SMART conditioning modules, is a real multipurpose layer. Practically any input; thermocouples, strain gages, accelerometers, microphones, amplified and unamplified transducers; can be utilized with this layer. Software selectable sample rates, transducer power, and digital filtering; simplify the set-up of any channel. There are also several calibration options including; defined value, external, multipoint; as well as shunt calibrations with embedded software tools when using the Strain SMART Module.

The EHLS is available with an optional Analog Out. Calibration files, directly compatible with popular simulation software, scale the analog outputs to engineering units.

Product Options

SoMat eDAQ Simultaneous High Level Layer, Analog Out (EHLS-AO)

The SoMat eDAQ Simultaneous High Level Layer, Analog Out (EHLS-AO) outputs are conditioned analog output signals that can be used in the creation of time-domain lab durability tests. When setting up the laboratory simulation, the SoMat eDAQ system is brought into the lab with the component or vehicle. This practice is highly recommended, as it ensures that all of the transducer instrumentation and properties are identical for the lab simulation as they were for the field data collection. Instead of being recorded, the analog out signals are sent as time series data for the test rig to analyze. The controller can then develop drive files that are played into the test rig reproducing exact field dynamics in the lab.

Benefits:

Consistency/Accuracy

The same signal conditioning, set-up file, and calibrations used in both the field and lab.

Ease of Set-up

Configure the eDAQ once, use it in both applications Analog Output Calibration File directly compatible with popular simulation software
