Smart Single Flange Pressure Transmitter

The ADDA-P Series smart single flange pressure transmitter uses monocrystalline silicon sensing technology for pressure and level measurement. It provides static pressure and temperature compensation and supports media compatible with the wetted materials. The maximum overload pressure also depends on the flange pressure rating.

Product Features

The ADDA-P Series uses a monocrystalline silicon sensor chip manufactured with advanced German MEMS technology and a dual-beam suspended design. It provides high accuracy, high overpressure resistance, and stable performance. An embedded signal processing module combines static pressure and temperature compensation to maintain measurement accuracy and long-term stability across a wide range of pressure and temperature conditions.

  • Monocrystalline silicon piezoresistive technology provides stable performance and accuracy up to 0.075%F.S.
  • Turndown ratio up to 100 : 1.
  • A high-performance EMC protection circuit module reduces the influence of electromagnetic interference on the output.
  • High stability: ±0.2% Span/5 years.

Applications

Pressure and level measurement.

Measuring Medium

Media compatible with the wetted materials.

High and low limit setting requirements: lower range value (LRV) and upper range value (URV) must be set within the lower and upper range limits, ｜URV-LRV｜≥ Minimum Range

*Refers to the maximum overload range of the sensor; the maximum overload range of the transmitter ultimately depends on the pressure rating of the flange
