SPIRIT AND PURPOSE
TRADEMARK PROSPECT
- MECHANICAL METERS AND DIAL THERMOMETERS
- Traditional mechanical gauges, core components with Bourdon Tubes, and dial thermometers with dual-metal or expansion-based detection methods observe pressure and temperature changes caused by conduction of media. The values are then determined and recorded via dial indicators.
- DIGITAL DISPLAY INSTRUMENTS
- Using pressure/temperature sensing elements, analog signals are converted into digital signals and displayed on digital displays, giving users a more convenient way to record and overcome the limitations of traditional dial indicators.
- SMART TRANSMITTERS
- Adopting world-leading HART® communication technology, smart sensors enable data observation via remote or on-site monitoring systems. This represents advanced instrumentation for industrial automation.
