1 Since 97 Specifications: Heavy Duty Bourdon Tube/Rotary Geared Movement Socket welded to Case Field Liquid Fillable Zero Adjustable Pointer HAWK 7L and 7B series bourdon tube all stainless steel pressure gauges are designed to fulfill the requirements of high quality from various industries. Because the socket of it is welded to the case, the gauge is stronger, more durable, and shockproof. This design also can eliminate the leak paths when the gauge is liquid filled and extend its service life. The 36SS construction pressure gauges are good in use on demanding applications where corrosion resistance, rugged environment resistance and reliable operation are required. These gauges are ideal to use combined with diaphragm seal where re-calibration is required. Series Typical Applications: Petrochemical and chemical processing Medical and pharmaceutical industry Industrial OEM equipments Food and beverage processing Hydraulic monitoring systems Power generating stations offshore oil platforms Pulp and paper mills Pneumatic systems Level measurement Operating: Steady: 00%*full scale value Pulsation: 90%*full scale value Sudden: 30%*full scale value The appropriate operating range falls in the middle half of the gauge(% to 7% of full scale). If you choose the unsuitable range, the fatigue of bourdon tube may be resulted. HAWK Supplies a wide selection of range from vacuum to 0000 PSI including compound range. Temperature limit: Ambient: -40 to 00 (Dry Gauge) -0 to 80 (Glycerine Filled Gauge) -0to80 (Silicon Filled Gauge) Media: max 0 (Standard) 300 (Optional) Temperature effect: Accuracy of measurement will be effected by the temperature change. This inaccuracy may as high as 0.3% for temperature change.
