Process automation

MESCO Engineering is your partner for electronics development for process automation products. From the concept phase through design and prototyping to certification according to international standards, we develop Embedded Hardware and Embedded Software for

• Transmitter and industrial measurement devices (pressure, temperature, level, flow, analyzer)
• Actuators (valves, valve controller, linear-, pneumatic and electrical actuators, pumps)
• Controller (process controller, gateways, I/O blocs).

Our solutions integrate modern industrial communication interfaces, including for use in potentially explosive atmospheres (Ex) and meet the highest requirements for functional safety (SIL), cybersecurity and reliability.

Our services in Process automation:

• Development of industrial electronics
• Design Requirements incl. Ex- and Functional Safety concepts
• Hardware and Software Design
• Prototype construction and product testing
• Support with required certifications
  (safety, explosion-protection, cyber-security, fieldbus, CE)

What sets us apart:

MESCO offers outstanding expertise in transmitter development. Our know-how covers both hardware development – from the implementation of intrinsic safe (Ex), ultra-low-power and miniaturized PCB layout as well as software solutions. This includes a signal conditioning, profile integration, monitoring functions, safety functions for normal operation monitoring and the integration of safe fieldbus systems.
