The gauges are designed in accordance with safety specifications of ASME B 40.1 and DIN 16006. The safety design consists of a solid wall between pressure sensing element and the window. In addition to protecting users from fluid and particles in the event of failure, the back of the gauges are designed to blow out and release the pressure inside the case. The designs provide a better safety for monitoring the gauge in the event of gauge failures. The gauges are widely used in chemical and petrochemical processing, food and beverage processing industries, plastic and paper manufacturing plants, oceanographic engineering, and various engineering projects.
