Heat Pumps - Slash your process Heating Bills by 50%. Heat pump is a device which is used to transfer heat energy from one place to another. Heat pump consists of four major components, namely, condenser, expansion valve, evaporator, and compressor, while refrigerant being the heat transfer media. Heat pumps usually can be used either in heating mode or cooling mode. When a heat pump is used for heating, it employs the same basic refrigeration-type cycle used by an air conditioner, but in the opposite direction – releasing heat into the conditioned space rather than the surrounding environment.  Heat pumps are increasingly used to heat water for Domestic, Commercial and Industrial applications. Through improvements in compressor operation and choice of refrigerants Heat Pump manufacturers are able to offer solutions up to 85°C process temperatures. Automotive manufacturing industry use Hot water for surface treatment and coating, paint spray booths, washing, rinsing etc...

Remote Collaboration for a Connected Plant. When you need more eyes and ears on mission critical task, then look for the RealWear. The RealWear hands-free is a powerful, fully-rugged, voice operated Android computer that is worn on the head and replaces the touch screen with an voice responsive articulated screen. The unit enables digital transformation in Industries with Microsoft Teams as a intrinsically safe solution to deploy a Remote hands-free Collaboration solution for seamless business continuity. Field operators can clip on the intrinsically safe units onto PPE hard hats in potentially hazardous environments. It's integrated with Microsoft Teams, which helps them communicate instantly across the globe with their Technical or Engineering person in real-time to quickly diagnose an operational issue or equipment maintenance or an unplanned emergency event at site. They can even have multiple people on Teams at once to look at a problem from all different poin...

Flying High ?...........At what Altitude ? You can find the Altitude by measuring pressure. Interesting ...? Read to know more.. Atmospheric pressure is caused by the gravitational attraction of the planet on the atmospheric gases above the surface. The standard atmospheric pressure or Barometric pressure at sea level on the Earth is 1013.25 mBar or 760mmHg. Pressure on Earth varies with the altitude of the surface. Atmospheric pressure decreases smoothly as the altitude increases. Altimeters measures absolute pressure to indicate the Altitude. At this point it's important to understand the difference between Absolute pressure and Gauge pressure. Absolute pressure uses absolute zero as its zero point, while gauge pressure uses atmospheric pressure as its zero point. Clear ? Due to varying atmospheric pressure, gauge pressure measurement is not precise, while absolute pressure is always definite. Hence for applications like Aerospace, Flight Instrumentation or Vacuu...

Are you still using Hand Pumps for Pressure Calibration ? There are lot of challenges when using a Handpump for generation of Pressure for Calibration Purpose. Pumping a large volume of media and precise adjustment of the generated pressure to required value is cumbersome and time consuming. Non availability of good quality hose or precise pressure adaptor may add further problems in the form of leakage. It's time you change the methodology of your pressure calibration. Precision pressure controllers are available which can quickly generate desired pressure accurate enough to test and calibrate present day smart transmitters at the touch of a button in seconds. Automatic increase or decrease of pressure enabling a 5 point calibration allows multiple calibration in the shortest span of time. Enormous calibration during shutdown becomes an easy task with Digital Pressure controller. Minor leakage is compensated unlike a hand pump. Calibration Softwares are available th...

Tungsten Carbide Thermowells in Challenging Temperature measurement Applications. Thermowells are used extensively throughout the Power, Process and Petrochemical industries to protect the sensors from the process fluid and to enable servicing, or replacement, of sensors without the need for plant shut down. Tungsten carbide contains equal parts of tungsten and carbon atoms as a fine gray powder, pressed and formed into shapes through a process called sintering for use in industrial machinery, cutting tools, abrasives etc. These thermowells are ideally suited for use in very abrasive environment such as in air preheaters & coal mills of coal based power plants, mill classifier, pulveriser outlet, steam generation units, for temperature measurement of coal and air mixture. In its monocarbide form, tungsten carbide is hardest and its impact resistance, toughness, and resistance to galling/abrasions/erosions are exceptional, lasting up to 100 times longer than steel in...

Why Electromagnetic Flow meters are so popular and preferable among all flow measurements? Electromagnetic flow meters detect flow by using Faraday's Law of induction. Electromagnetic flow meter does not leave any obstructions in the pipe, so they can be used for measuring heavy suspensions, including mud, sewage, wood pulp etc. Obstructionless and choice of liners with abrasion and erosion resistance properties make it suitable for Sewage, Waste Water, Chemicals, Slurries etc. Electromagnetic flow meters are very well recommended for food grade applications like Juices, Milk, Municipal or Industrial Water etc. There is no pressure head loss resulting in Energy savings. They are practically unaffected by variation in density, viscosity, pressure, temperature and upstream flow disturbances. And more importantly its Economical, Bi-directional, No moving parts and hence no wear and tear and hence Long Life. Only criteria is liquid should be Conductive. Let us know ...
