Hydraulic fluid control

Dilemma : Fluid control has become an unavoidable action to ensure high system reliability and increased efficiency of hydraulic and lubrication systems in following ways :

The control of liquid level in reservoirs, gear boxes and other complex constructions.

The ingress of water into fluid power or lubrication system will reduce lifetime of oil significantly and will caused damage to many components.

A stable operating temperature is essential for precise and trouble-free operation of hydraulic and lubrication systems.

Electro pneumatic / pneumatic Positioner position transmitter

Next generation of Positioner design featuring better performance and ease of setup has taken

Rotex Automation offers electro pneumatic positioner RTX1000 model with world class features.

Rotex has achieved ISO 9001:2000 by TUV and approvals like ATEX, PED, INMETRO, UL, CCOE, CMRI and Bureau of business standards for its explosion proof application for solenoid valves and limit switches. Also Rotex conforms to some of the highest design standards in India and the world, including: En, ISO, ANSI, ASTM, BIS, PIN, NSCE AND IEEE.

Features :

  • Compact design, rugged construction with rigid ISO 5211 Mounting
  • Vibration resistant because of its unique design and construction
  • Quick and ultra-precise response of the torque motor
  • Special polymer shaft bush with built in grease reservoir to avoid shaft seizure due to formation of Aluminium oxide
  • Split range control can be easily adopted by change in few internal components
  • Simple to convert from direct acting to reverse acting or vice versa
  • The springs exhibit a stable force along with a highly balanced diaphragm
  • Low hysteresis due to lip seal instead of an O-ring which result in high gain and low friction
  • Various orifice size option available for different volume of actuator to prevent from hunting and also for controlling speed
  • Easy and precise calibration with Zero and Span adjustment
  • All the internal parts are hard anodized
  • Bright visual indicator on both flat and high dome type positioners
  • Internal and external mounting of the position transmitter and limit switch made possible and easy
  • No component is exposed, thus preventing from corrosion in hazardous environment
  • IP66 protection
  • CE certified

Automation via Supplier Scorecard

Automation must include the ability to identify riskiest suppliers via a supplier scorecard. Using technologies to determine risk trends for key problems as well as comparing risks across alternate suppliers allows for lean best-practices among all manufacturing operations, especially food and beverage.

More effective software engineering with TwinCAT 3.1

Extended range of functions and new features with TwinCAT 3.1

The integration of Visual Studio® into TwinCAT connects the standard development environment from Microsoft with the proven Beckhoff automation technology. It is evident that the product philosophies of TwinCAT and Visual Studio® are ideally suited to each other. The result of this integration is simplified software engineering for automation technology: the programming languages and platforms are freely selectable. Source code control tools can be simply integrated and the automatic generation of code will replace many manual steps in the future. The TwinCAT runtime system enables the distribution of the tasks to different cores and will thus increase the performance several times over. 64 bit operating systems are also supported from TwinCAT version 3.1

Float Type Level Switches, Top bottom/ Side mounting

The Mifa systems offers float type top and side mounting level switches for above ground storage tanks, underground storage tanks sumps dry annular spaces.

GEMS Level Switches operate on a direct, simple principle. In most models, a float encircling a stationary stem is equipped with powerful, permanent magnets. As the float rises or lowers with liquid level, the magnetic field generated from within the float actuates a hermetically sealed, magnetic reed switch mounted within the stem. The stem is made of non-magnetic metals or rugged, engineered plastics. When mounted vertically, this basic design provides a consistent accuracy of ±1/8 inch. Multi-station versions use a separate reed switch for each level point being monitored.
