YQF-100 YQF-150 series stainless steel safety pressure gauge according to the enterprise. "" "Safe gauge standard manufactured goods for use in harsh and corrosive environments. Designed with safety separator in the table. Back with a relief cover and relief holes to release the internal pressure overload generated by break of elastic component, enhance the security of personnel and facilities. "" All Stainless Steel Pressure Gauges with a filling plug and an internal compensation diaphragm, field filling. filling Safety pressure gauge with a shock and damping properties, can prevent vibration of the gauge internal damage, while also lubricating the internal components to reduce corrosion. This series instruments are widely used in food, medicine, oil refining, chemical, offshore oil platforms, drilling, shipbuilding and other industries I. Features: ● Full stainless steel design, corrosion resistance ● high voltage measuring to 100MPa ● safety baffle means, back pressure relief ● ● safe double glass protection measure Accuracy ± 1.0% ± 1.6% Second, the major technical indicators: Accuracy ± 1.0% ± 1.6% Case dimensions 100mm 150mm Case Material 304 Stainless Steel Case form after the containment structure, the baffle means delivery tube and connected with 316 stainless steel pipe 316 stainless steel connecting body movement 316 stainless steel arc welding of connection M20 × 1.5 or 1/2 NPT bottom connection, or back connection (radial / axial) Measuring range -0.1 ... 0 MPa, 0.1 ... 100 MPa Pointer ordinary table glass glass, double glazing safe seismic-type filling material glycerol 98% (optional silicon oil, fluorine oil or other category) protection class IP 65 ambient temperature and working medium temperature should not exceed: filling type 0 to 140 ℉; common type -40 ~ 140 ℉ Third, pay attention: when a strong oxidizer mixing glycerol or silicone grease and chlorine, nitric acid, nitrogen oxides, etc., it will spontaneous chemical reaction, fire or explosion resulting in equipment damage, casualties possible. When the pressure gauge used for these occasions can not be filled with silicone oil or grease glycerol, please contact the manufacturer, fill in the correct oil-filled. "
