Description
Differential pressure transmitter for level applications
Pressure device for measuring differential pressure in industrial and non-industrial environments. The metallic sensor provides outstanding long-term stability and single-sided overpressure resistance. It can be supplied with a wide range of process connections and fill fluids
Advantages
- Level, content or volume measurement in pressurised vessels or vessels under vacuum
- Differential pressure measurement of hazardous and harmful products
- Long term stability < 0.05% per 5 years minimises recalibration
- Integrated linearisation of vessels (horizontal or vertical)
- HART, PROFIBUS and FOUNDATION Fieldbus compatible
- Menu-guided display with plain text – no error codes to decipher • No software or handheld communicators required
- Available with TempC membrane for improved accuracy and process safety in difficult pressure and DP applications
