Product Description
Product Description
DSS10M is a threaded diaphragm sealed pressure gauge developed by WIKA for the chemical, petrochemical, and general process industries. It is used to isolate highly corrosive, high-temperature, high viscosity, or toxic media and protect the pressure gauge core.
The diaphragm sealing system is used to protect pressure measuring instruments from corrosive, viscous, crystalline, corrosive, high viscosity, environmentally harmful or toxic media. A diaphragm made of stainless steel is used for separating from the medium. The pressure is transmitted to the measuring instrument through the system filling fluid inside the diaphragm sealing system.According to the standard, the diaphragm seal is installed directly onto the measuring instrument. DSS10M is particularly suitable for aggressive or high-temperature media. This instrument is mainly suitable for applications in the process industry.
Core Features
Strong medium isolation: Fully welded 316L diaphragm isolates corrosive, viscous and crystallizing media to prevent internal core contamination.
High temperature resistance: Direct measurement of media up to 150℃ without condenser tubes for easier installation.
Replaceable design: The lower body (diaphragm part) can be disassembled and replaced separately without scrapping the entire gauge, leading to low maintenance costs.
General industrial thread: 1/2" NPT/G1/2 standard interface, which can be directly screwed onto pipelines without drilling holes on panels.
High Precision + IP65: Class 1.0 precision with IP65 protection rating, suitable for outdoor and harsh environments.

A pressure transmitter converts the pressure of liquid, gas or steam into a standard electrical signal for PLC, DCS, recorder or control instrument input. It is widely used for pipeline pressure, tank level, flow measurement and process safety monitoring.
Confirm the pressure range, pressure type, medium, temperature, output signal, accuracy, installation thread, electrical connection and environmental requirements. For corrosive media, high temperature or sanitary applications, diaphragm material and sealing structure are especially important.
Gauge pressure transmitters measure pressure relative to atmospheric pressure. Absolute pressure transmitters measure pressure relative to vacuum. Differential pressure transmitters measure the pressure difference between two points and are commonly used for flow, filter and level measurement.
