Hydac Electronic Pressure Transmitter For shipbuilding and offshore HDA 3400

Hydac Electronic Pressure Transmitter For shipbuilding and offshore HDA 3400

This pressure transmitter, which has been specially developed for shipbuilding and offshore applications, is based on a very robust DMS sensor cell.

All parts in contact with the fluid are instainless steel, and are welded together. Since no seals are required in the sensor chamber, leakage is eliminated.

The 4 .. 20 mA output signal in two conductor technique enables connection to the relevant evaluation electronics.

Areas of application are pressure monitoring on marine transmissions, diesel engines, pumps and general hydraulic and pneumatic systems.

Hydac Electronic Pressure Transmitter HDA 3800 for Iron & Steel Works Applications

Hydac Electronic Pressure Transmitter HDA 3800 for Iron & Steel Works Applications

This high-precision pressure transmitter has been specially developed and adapted for the sophisticated measurement demands of steelworks technology.

The instrument has a very robust sensor cell with a thin-film strain gauge on a stainless steel membrane. Its outstanding specifications in respect of temperature effect (temperature drift for zero point and range are in each case max.
≤ ± 0.01 % FS / °C) and accuracy
(≤ ± 0.15 % FS typ.) make it ideally suited for use in the environmental conditions found in steelworks.

The excellent EMC characteristics guarantee signal stability during the harshest high-frequency, electro-magnetic interference.

Special features:

• Accuracy ≤ ± 0.15 % FS typ.
• Specially designed for use in steelworks and rolling mills.
• Highly robust sensor cell.
• Very small temperature error.
• Excellent EMC characteristics.
• Excellent long term stability.
