ELSTAR manufactures a comprehensive range of signal analysis equipment with emphasis on machine vibration measurement. This together with representing world class sensor manufacturers allows us to provide you with a complete solution to your measurement, production testing and condition monitoring requirements.   

Rotating Machinery Analysers Starline Sensors

ELSTAR equipment is designed and developed by engineers with extensive experience in the field of machinery diagnostics. This results in supplying measurement equipment that focuses on the practicalities of field measurements.

ELSTAR CALSTAR is a multi purpose calibration system designed to work as a stand alone vibration transducer calibrator, a balance facillity bearing pedestal stiffness measuring system or a Cabstar signal line calibrator. 

DytranLogo Blue have been manufacturing accelerometers and force sensors for more than 30 years. Whether you are looking for high temperature (up to 650°C), miniture tri-axial or smart (USB) accelerometers Dytran has a model to suite your requirements.Dytran is also a leading supplier of HUMS accelerometers for helicopters. If you require guidance on selecting the correct sensor for your application just open the Product Configurator or give a call, we will be happy to assist you.

tiltex fontis ELSTAR's wireless angular measurement module. It is utilised in conjunction with our Orbistar wireless run out measurement system. Simply mount TILTEX on your Rotor using it's built in magnetic mounts, connect wirelessly to Orbistar. TILTEX will continuosly send live angular information.

When acquiring data in a measurement task that requires multi channel data to be collected in a manner suited to different measurement types .

Let's say you are faced with a measurement task where some channels measure vibration on a fixed frequency range at a sample rate of 2kHz and others are measuring temperature say every 10 seconds. If all your channels are locked together  using the same the data acquisition set up, you must choose the vibration set up for all channels. This is just fine for the vibration analysis, but you are taking a way too much data for your temperature channels.

The solution is to set your Corvus system up with two processes one sampling at 2kHz and the one shot every 10 seconds. You just allocate the relevant channels to their measurement process. The measurement system needs to be able to synchronise all processes so that the data can be displayed live or recorded and played back with all channel data with the correct timing.

There are two levels of Corvus:

  • Corvus Lite - Supports up to 268 dynamic or static (machine variables) channels and up to 2 measurement processes.

  • Corvus Full - Supports up to 1024 dynamic or static (machine variables) channels and up to 8 measurement processes that can be distributed on up to 8 data collection PC's.

A system where up to 8 processes can be defined in a single data acquisition station situated remotely (over the Ethernet) up to 100m away from the workstation running Corvus. The channel count is limited only by the capability of the hardware. The data acquisition station can be positioned close to the measurement points reducing cable lengths and thus improving the signal quality.

Data Acquisition hardware: National Instruments PXIe-1082 portable 8 Slot rack with PXIe-8840 controller. A combination of up to 8 different Data Acquisition card types. Analog channel count 128.

Computer: Any PC running Windows 7 SP1 or above. 

A system where up to 6 remote data acquisition stations each running up to 8 processes can be defined. Each data acquisition station can be situated remotely (over the Ethernet) up to 100m away from the workstation running Corvus. The channel count is limited only by the capability of the hardware. The data acquisition stations can be positioned close to the measurement points reducing signal cable lengths and thus improving the signal quality.

Data Acquisition hardware: 6 x National Instruments PXIe-1082 portable 8 Slot racks with PXIe-8840 controller. A combination of up to 8 different Data Acquisition card types per rack. Analog signal channel count 768

Computer: Any PC running Windows 7 SP1 or above. 

This is a highly portable entry level system.You just need Corvus Lite,a Notebook PC and a compact National instruments USB-9234 4 channel data acquisition module and your ready to start measuring.

The USB-9234 has a switchable IEPE constant current supply built in which enables you to connect a wide range of sensors eg. Dytran Accelerometers, directly to the BNC inputs.

This is a very powerfull analyser with recording direct to disk whils displaying real time data in a wide range of plot formats.

Data Acquisition hardware: National Instruments USB-9234.

Computer: Any Portable PC running Windows 7 SP1 or above (Must support at least 1 USB port, Ethernet or Wireless). 

An extremely flexible portable system. You can add up to 32 channels as required to suite your measurement task, or you can mix 2 module types in one compaq Daq chassis as Corvus Lite supports 2 Processes.

Data Acquisition hardware: National Instruments cDAQ-9178 for USB control or cDAQ-9189 for Ethernet control. Up to 8 NI-9234 4 channel modules or a second type of CDAQ module.

Computer: Any Portable PC running Windows 7 SP1 or above (Must support at least 1 USB port, Ethernet or Wireless). 

A powerful rotating machinery analysis system that you can take to site and attach up to 32 dynamic channels or split into two processes and measure dynamic signals such as vibration and a second process for slow changing machine condition signals. Machine runups and rundown can be analysed and at the same time streamed direct to disk so that no data is lost and the data replayed for re-analysis later.

Data Acquisition hardware: National Instruments cDAQ-9178 for USB control or cDAQ-9189 for Ethernet control. Up to 8 NI-9234 4 channel modules or a second type of CDAQ module.

Computer: Any Portable PC running Windows 7 SP1 or above (Must support at least 1 USB port, Ethernet or Wireless). 

Corvus options: Option 1- Ring BufferOption 3- Streamed Data Storage,  Option 18-Rotor Analysis Toolkit

ELSTAR has wide experience in supplying sensors chiefly in the area of vibration and Rotating machinery applications. These can be broken down ito three catagories.

Corvus is Elstars general purpose, highly scalable vibration signal analyser.

We can deliver Corvus as a compact Lite version set up as a 4 channel portable analyser right up to a Corvus Full version with a configuration of up to a 1000 channels set up as a  multi process distributed analysis system.

With the abillity to be connected to a wide range of hardware suppliers, Corvus makes it simple to meet your measurement requirements.

Corvus is an open system in terms of hardware and supports, but is not limited to, a wide range of National Instrument devices.

There are two levels of Corvus:

Corvus Lite - Supports up to 268 dynamic or static (machine variables) channels and up to 2 measurement processes.

Corvus Full - Supports up to 1024 dynamic or static (machine variables) channels and up to 8 measurement processes that can be distributed on up to 8 data collection PC's.

As a guide, we have put together a series of packages for both levels of systems based on National Instruments hardware.
