4-1/2" Process Pressure Gauges (NACE)
Process gauge engineered for the oil and gas and industrial process industries. In the event of over-pressuring resulting in a leak, a solid wall separates the rupture forcing the process media through blowing out the back of the gauge. Used in refineries, chemical plants, industries, etc. Where operator safety and accuracy are very important factors.
