If the diaphragm is of the welded type, loosening the fastening bolts makes it easy to clean the diaphragm surface.
The "Model 841A" is a pressure gauge that seals liquid as a pressure transmission medium between the pressure receiving surface (diaphragm) and the Bourdon tube. Since the diaphragm can be selected according to the application, it is suitable for measuring highly corrosive fluids and high-viscosity fluids. You can also choose a specification that allows for remote measurement by connecting the pressure receiving part and the indicator with a lead. 【Features】 ■ Special corrosion-resistant materials such as stainless steel, tantalum, and Teflon can be used for the diaphragm material. ■ Zero point adjustment pointer is standard equipment. ■ Easy correction of temperature and other errors. ■ The flange is connected by an intermediate pipe, allowing for no restrictions on flange size. * For more details, please refer to the PDF document or feel free to contact us.
