Data Acquisition System

TMCS undertakes key projects on DAQ Products, where products are used to gather information from different ongoing occurrences into the computer for processing, documenting, studying, storing and signal conditioning.

What is Data Acquisition (DAQ)?

Data Acquisition Systems have its contribution in a wide range of activities of day-to-day life. Most commonly, it is used to measure the electrical signals from some is often referred, is the process of digitizing data from the world around us so it can be displayed, analysed, and stored in a computer.

DAQ system applications are usually controlled by software programs developed using various using general purpose programming language such as Assembly, BASIC, C, C++, C#, Fortran, Java, LabVIEW. TMCS is NI Silver Alliance Partner we also provide LabVIEW Software offshore consultation.

Data Acquisition System: Applications of DAQ Software

A DAQ system consists of:
  • Transducer
  • Data Acquisition Hardware (DAQ)
  • Computer

A transducer or sensor converts a physical phenomenon into a measurable electrical signal that a DAQ system measures.

Transducers used for a variety of applications from measuring temperature to pressure to fluid flow.

A typical data acquisition system based on virtual instrumentation consists of five parts

Sensors – Convert physical phenomena into a signal you can measure

Signals – The signals you are acquiring or generating with your data acquisition system.

Signal conditioning hardware – Used to remove noise, amplify the signal, or excite sensors. This hardware is sometimes integrated with DAQ hardware.

DAQ hardware – The interface between the computer and the outside world. Its primary function is to convert analog signals to digital so that the computer can interpret them.

Software – Measurement Services software forms the layer between the hardware and your application software. It should provide configuration and installation services, a programming interface, self-calibration, and other features to simplify the interface with DAQ hardware. Application-level software is the program you develop using a standard programming environment such as LabVIEW, C, or Visual Basic.

Signal Conditioning Hardware - Modular signal conditioning lets you customize the signal conditioning on a module-by-module basis, allowing you to easily mix and match different signals into one DAQ system.

Components of Data Acquisition System:

Modern digital data acquisition systems consist of four essential components that form the entire measurement chain of physics phenomena:

  • Sensors
  • Signal Conditioning
  • Analog-to-Digital Converter
  • Computer with DAQ software for signal logging and analysis

The Purposes of Data Acquisition

The primary purpose of a data acquisition system is to acquire and store the data.Data acquisition systems are principally in the business of measuring physical phenomena such as:

  • Temperature
  • Voltage
  • Current
  • Strain and Pressure
  • Shock and Vibration
  • Distance and Displacement
  • RPM, Angle, and Discrete Events
  • Weight

We undertake projects for DAQ :

Connect any make PID’s, configure them over Modbus and start using the software

NI hardware based DAQ System:

Data acquisition systems with different National instruments platforms like cRIO, PXI, cDAQ, SCXI, etc.

Data Acquisition and Control System for Crank Shaft Hardening:

Temperature data logging from sensors like RTD, Thermocouple, etc and Energy monitoring from different make energy meters or power analysers like Yokogawa, Rishabh, Schneider, etc.

Chiller Monitoring System:

A distributed chiller monitoring system used to monitor and maintain various parameters of climatic chambers like temperature, pressure, energy, and flow of refrigerant.

Customized Data Acquisition Software

Customised Data Acquisition Software of Power Analysers:
TMCS Data Acquisition system specially developed for compressor monitoring.

Distributed Data Acquisition System:

Collecting data from different stations and Data logging of many stations to a single server and integration with existing SAP and ERP system.

Fast /High-Speed Data Acquisition and Control System:

System was developed to capture high-speed data from about 50 analog input channels. The Acquisition rate per channel was 1msec. Based on the analog input some control logic was developed to control 30 analog output channels simultaneously.
