Process Instrumentation System | Vaisala
Johor, JB, Malaysia
The Vaisala process instrumentation system is a comprehensive ecosystem of industrial measurement technologies engineered for real-time automation, quality control, and energy optimization across manufacturing environments. The architecture relies heavily on modular hardware that seamlessly transmits critical environmental and liquid data directly into distributed control systems (DCS).
Core Measurement Technologies
Vaisala divides its industrial instrumentation into two main processing categories:
Liquid Concentration Systems: Centred around the 5th-generation Vaisala Polaris Product Family, which utilizes inline refractive index technology to monitor industrial fluids.
Gas & Environmental Systems: Built on the modular Vaisala Indigo Platform featuring smart, interchangeable probes for gases and physical process boundaries.
Key System Components
1. Polaris Inline Process Refractometers
Following the acquisition of K-PATENTS, Vaisala updated its optical measurement technology to deliver maintenance-free, drift-free liquid data:
PR53AC & AP Series: Sanitary-grade systems designed specifically for food, beverage, dairy, and life science applications.
PR53GC & GP Series: Industrial probe designs built to measure chemical solutions, sugar crystallization, and oil refining processes.
PR53M & W Series: Engineered with specialized ultra-pure PTFE or heavy-duty valve bodies to withstand aggressive acids like H₂SO₄ and HCl.
PR53SD Series: Optimized for the heavy pulp and paper industry to manage black and green liquor concentration lines.
The Vaisala Indigo Family acts as a flexible data translation layer for environmental metrics:
Host Transmitters: Devices like the Indigo520 or Indigo300 accept interchangeable inputs, providing a localized physical display and multi-parameter scaling.
Gas & Dew Point Probes: Smart sensors that integrate seamlessly to measure relative humidity, temperature, CO₂, vaporized hydrogen peroxide (vH₂O₂), and trace dew point moisture.
3. Industrial Infrastructure & Software
Connectivity Protocols: Systems natively generate analog 4-20 mA loops or digital Modbus RTU, Ethernet, and serial telemetry directly into plant automation frameworks.
Insight PC Software: A specialized interface that allows calibration, diagnostics, and over 500 pre-installed chemical curve configurations to be managed from an engineering workstation.
