Product catalog summary

Overview: The DMK 456 is a pressure transmitter designed for marine and offshore applications, featuring a stainless steel field housing. It is suitable for measuring pressure in systems and levels in tanks, particularly under extreme conditions involving aggressive gases and fluids.

Specifications:

Accuracy: Standard accuracy is 0.25% FSO, with an optional accuracy of 0.1% FSO for nominal pressures ≥ 0.6 bar.
Pressure Range: Nominal pressure ranges from 0.04 bar to 20 bar, with permissible overpressure up to 45 bar.
Output Signal: Standard 2-wire 4-20 mA, with other options available upon request.
Temperature Range: Medium temperature from -25°C to 125°C, electronics/environment from -25°C to 85°C, and storage from -40°C to 100°C.
Materials: Pressure port and housing made of stainless steel 1.4404 (316L), with a ceramic diaphragm option of Al2O3 99.9%.

Certifications:

LR-certificate (Lloyd's Register)
DNV-approval (Det Norske Veritas)
ABS-certificate (American Bureau of Shipping)
CCS-certificate (China Classification Society)

Features:

High overpressure resistance and intrinsic safety for gases (temperature class T6).
Robust design suitable for harsh environments.
Long-term stability of ≤ ± 0.1% FSO per year under reference conditions.

Applications:

Monitoring pressure during loading and unloading processes.
Monitoring ship's position and draught.
Use in anti-heeling systems and level measurement in ballast and storage tanks.
Monitoring internal pressure in liquid gas cargo tanks.

Installation and Compatibility:

Ingress protection rated at IP67.
Compatible with various mechanical connections and seal materials.
Electromagnetic compatibility according to EN 61326 and DNV standards.
