Product Description
Product Description
The models 262 and 263 are high-quality Bourdon tube pressure gauges with wetted parts from extremely corrosion-resistant Monel.
The use of high-quality materials and the robust design are geared to applications in the chemical and process engineering industries with particularly aggressive acids or bases. The instrument is suitable for liquid and gaseous media, also in aggressive environments.Scale ranges of 0 ... 0.6 to 0 ... 1,000 bar [0 ... 10 to 0 ... 15,000 psi] ensure the measuring ranges required for a wide variety of applications.
The safety version is made up of a non-splintering window, a solid baffle wall between measuring system and dial and a blow-out back. In the event of a failure, the user is protected at the front side, as media or components can only be ejected via the rear of the case.For harsh operating conditions (e.g. vibrations), all instruments are also available with an optional liquid filling.
Special Features
With case filling (model 263) for applications with high dynamic pressure loads and vibrations.
Suitability for particularly aggressive media, due to very high corrosion resistance.
EMICOgauge version, to avoid fugitive emissions.
QR code on dial links to instrument-specific information.
Applications
For gaseous and liquid aggressive media that are not highly viscous or crystallising, also in aggressive environments.
Oil and gas industry, chemical and petrochemical industries, power engineering and also water and wastewater technology.
Sour gas applications, also with NACE requirement.

| Applications | Pipeline pressure, tank level, flow differential pressure, hydraulic pressure and automation systems |
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.
Yes. Xinyi Instrument can support customized pressure ranges, process connections, output signals, cable length, display options and model selection for different industrial applications.
