Revolution. A completely new diaphragm pressure gauge that does not use filling liquid has arrived.
This is a pressure gauge specially designed for industries such as food, pharmaceuticals, and cosmetics, where cleanliness and safety are the top priorities.
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.
Special corrosion-resistant materials such as stainless steel, tantalum, and Teflon can be used for diaphragm materials.
The "Model 841B" is a pressure gauge that seals liquid as a pressure transmission medium between the pressure-sensitive surface (diaphragm) and the Bourdon tube. It is suitable for measuring highly corrosive fluids and high-viscosity fluids because the diaphragm can be selected according to the application. Compared to the 841A model, it is suitable for installation in locations with limited height since there is no intermediate pipe. 【Features】 ■ Special corrosion-resistant materials such as stainless steel, tantalum, and Teflon can be used for the diaphragm material. ■ A specification that allows for remote measurement by connecting the pressure-sensitive part and the indicator with a lead is also available. ■ Standard equipped with a zero point adjustment pointer. ■ Easy to correct errors due to temperature and other factors. ■ The flange is directly connected to the instrument mounting bracket, resulting in a structure with minimal liquid accumulation. *For more details, please refer to the PDF document or feel free to contact us.
A specification that allows for remote measurement is also available! Pressure gauge with screw connection type.
The "Model 841S" is a pressure gauge that encloses liquid as a pressure transmission medium between the pressure-sensitive surface (diaphragm) and the Bourdon tube. It is suitable for measuring highly corrosive fluids and high-viscosity fluids, as the diaphragm can be selected according to the application. It features a screw connection type. 【Features】 ■ Special corrosion-resistant materials such as stainless steel, tantalum, and Teflon can be used for the diaphragm material. ■ A specification that allows remote measurement by connecting the pressure-sensitive part and the indicator with a lead is also available. ■ Standard equipped with a zero point adjustment pointer. ■ Easy to correct errors due to temperature and other factors. ■ If the diaphragm is of the welded type, cleaning the diaphragm surface is easy by loosening the fastening bolts. *For more details, please refer to the PDF document or feel free to contact us.
Due to the oil-free structure, temperature drift is reduced, allowing for use at high temperatures!
The "Model 830, 831" is a diaphragm pressure gauge with an oil-free structure that does not use filling liquid. In the unlikely event that the pressure receiving part is damaged, there will be no leakage into the line. Additionally, it has less temperature drift compared to conventional liquid-filled types, making it suitable for high-temperature use. The wetted parts are made of stainless steel, which offers excellent corrosion resistance. 【Features】 ■ Oil-free structure that does not use filling liquid ■ No leakage into the line even if the pressure receiving part is damaged ■ Suitable for high-temperature use ■ Wetted parts made of stainless steel ■ Excellent corrosion resistance *For more details, please refer to the PDF document or feel free to contact us.

Diaphragm pressure gauge with selectable connection parts and materials tailored to the application.
This is a pressure gauge that features a diaphragm between the fluid to be measured and a Bourdon tube pressure gauge, filling the space between the pressure-receiving part and the Bourdon tube element with a filling liquid to serve as a medium for pressure transmission. The materials for the connection part and the diaphragm can be selected according to the application, making it suitable for measuring corrosive fluids, highly viscous fluids, and fluids that tend to solidify.
Standard equipped with zero point adjustment guide! A smaller flange can be installed!
The "Model 841C/841D" 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. Compared to the 841B model, a smaller flange can be installed. 【Features】 - Special corrosion-resistant materials such as stainless steel, titanium, and Hastelloy can be used for the diaphragm material. - A specification that allows for remote measurement by connecting the pressure receiving part and the indicator with a lead is also available. - Zero point adjustment pointer is standard equipment. - Corrections for temperature and other errors can be easily made. *For more details, please refer to the PDF document or feel free to contact us.
High-temperature diaphragm pressure gauge that allows for easy correction of temperature and other errors.
The "841A・B・C・S type" is a diaphragm pressure gauge that can be used in high-temperature areas where the temperature of the measured fluid exceeds 200°C. Special corrosion-resistant materials such as stainless steel and tantalum can be used for the diaphragm material. It comes standard with a zero adjustment pointer, making it easy to correct for temperature and other errors. Additionally, a specification that allows for remote measurement by connecting the pressure receiving part and the indicator with lead can also be selected. 【Features】 ■ Can be used in high-temperature areas where the temperature of the measured fluid exceeds 200°C ■ Special corrosion-resistant materials such as stainless steel and tantalum can be used for the diaphragm material ■ A specification for remote measurement is also available ■ Standard equipped with a zero adjustment pointer ■ Easy to correct for temperature and other errors *For more details, please refer to the PDF document or feel free to contact us.
