Chemical & Petrochemical Pressure Transmitters
The chemical and petrochemical sector demands more from pressure instrumentation than almost any other industry. Corrosive feedstocks, toxic intermediates, explosive atmospheres, and extreme process temperatures are routine rather than exceptional. Stork Solutions supplies a comprehensive range of ATEX/IECEx approved pressure transmitters and level sensors engineered to operate reliably in these conditions, with intrinsic safety (Ex ia), SIL 2 functional safety certification, and material options specifically selected for aggressive chemical service. From reactor pressure control and storage tank monitoring to pipeline integrity and scrubber level measurement, our instruments are built to perform where failure is not an option.
Key Chemical & Petrochemical Applications:
Pressure Transmitters for Corrosive and Hazardous Chemical Processes
Chemical processing environments expose instrumentation to acids, alkalis, solvents, and reactive intermediates that would destroy conventional sensors within weeks. Stork Solutions addresses this with transmitters built around chemically resistant sensing technologies. The DMK 331 features a flush-mounted ceramic sensor and offers a PVDF pressure port for direct compatibility with aggressive media such as sulphuric acid, hydrochloric acid, and caustic soda. For applications requiring higher overpressure resistance and a capacitive ceramic diaphragm (99.9% Al2O3), the DMK 351 provides outstanding chemical resistance across a 0 to 20 bar range, with intrinsically safe versions available for both gas and dust hazardous areas. Where flush diaphragm construction is needed for viscous or crystallising media in chemical reactors and dosing systems, the DMK 351 P adds hygienic-style process connections and the same robust ceramic sensing platform.
High Pressure and Ultra-High Pressure Measurement for Petrochemical Applications
Petrochemical plants routinely operate at pressures that push instrumentation to its limits. Hydrocracking, polymerisation, and high-pressure gas compression all require transmitters that combine extreme pressure capability with long-term measurement stability. The DMP 333 handles pressures up to 600 bar with excellent insensitivity to pressure spikes and dynamic loading, making it well suited to hydraulic test loops and high-pressure pipework. For even more demanding service, the DMP 334 extends the range to 2,200 bar using a thin-film sensor welded directly to the pressure port for maximum operational safety. Where precision is critical at these pressures, the DMP 334 i adds digital signal processing with active correction of non-linearity and thermal error, delivering a 1:10 turn-down ratio for flexible range adjustment without hardware changes. For ultra-high pressure applications up to 6,000 bar, such as water jet cutting systems and high-pressure chemical injection, the DMP 304 provides ATEX-certified measurement with 0.25% FSO accuracy.
Level and Pressure Monitoring in Chemical Storage and Containment
Accurate level and pressure data in chemical storage tanks, bund areas, and intermediate bulk containers is essential for inventory management, overfill prevention, and regulatory compliance. The LMK 351 screw-in level transmitter uses a flush-mounted capacitive ceramic sensor with a PVDF pressure port, making it directly compatible with aggressive liquids including acids, alkalis, and solvent-based chemicals. For general process pressure monitoring across the plant, the DMP 331 offers a proven silicon sensing platform with SIL 2 compliance and intrinsic safety certification, covering pressure ranges from 100 mbar to 60 bar. Both products support 4-20 mA output as standard, with customer-specific configurations available for integration into existing DCS and SCADA architectures.
Digital and Smart Transmitters for Chemical Plant Modernisation
As chemical and petrochemical operators invest in digitalisation and predictive maintenance strategies, smart instrumentation becomes a key enabler. The DMP 331i / DMP 333i precision pressure transmitters use 16-bit digital signal processing to deliver thermal error as low as 0.02% FSO/10K, with a communication interface for remote adjustment of offset, span, and damping. For plants adopting IO-Link networks, the DCT 533 brings standardised digital communication (IEC 61131-9) to pressure measurement, enabling faster commissioning, real-time diagnostics, and simplified device replacement without manual reconfiguration. These smart transmitters reduce the total cost of ownership across large chemical installations by cutting commissioning time, improving measurement transparency, and supporting condition-based maintenance programmes.
Specify the Right Transmitter for Your Chemical or Petrochemical Application
Every chemical process presents a unique combination of media compatibility, pressure range, temperature exposure, hazardous area classification, and communication requirements. Stork Solutions’ UK-based technical team works with chemical engineers, instrument engineers, and system integrators to specify the right transmitter for each measurement point, whether that is a single replacement sensor or a full plant instrumentation package.
