• Ravika engineers introduces dead weight pressure gauge testers with water as the operating fluid for applications in food, drugs, oxygen, nitrogen and acetylene industries. All wetted parts shall be of stainless steel. Also available a wide range of testers for calibrating pressure gauges and other pressure sensing, transmitting and recording pressure instruments up to 1000 kg/cm2. Relationship between pressure acting on the known area of a vertically free floating piston producing a force balanced by known dead weights is made use of in this tester. It has a built-in screw pump of adequate capacity to generate pressure by turning a handle permitting easy and accurate settings. Free piston assembly of special steel, hardened, tempered, stress relieved (artificially aged), ground and superfinished to accurate size and very fine surface finish provides true floating action. Set of weights of phosphated ms or ss 304, directly marked in convenient values of pressure and easily stackable on the weight carrier, attached to the free piston is provided. The testers are available in kg/cm2, bar, kpa, mpa, ib/in2 units. Accuracies of ±0.1% ±0.06% and ±0.03% with national traceability are available. Electrical motor rotation for free piston and weights at speeds of approx 30 rpm can be provided..
