Winters Instruments PTR Tamper Resistant Process Gauge is an integrated pressure gauge and diaphragm seal assembly engineered for applications where tamper resistance, process safety, and measurement reliability are critical. The gauge is permanently welded to a 316L stainless steel diaphragm seal, creating a sealed system that helps prevent leaks and eliminates common field assembly errors.
Featuring a solid-front safety case, pressure relief back, and silicone-filled sealed system, the PTR gauge is designed to deliver dependable performance in demanding industrial environments. Its robust stainless steel construction makes it suitable for corrosive media and process applications across oil & gas, petrochemical, chemical, and general process industries.
