Industrial automation sensor with multivariate data collection

  • Digital MODBUS RTU and Alicat® ASCII, or analog 4–20 mA I/O
  • Up to 13 reported parameters on flow, pressure, temperature, totalizer, and humidity
  • Fewer components, by combining measurement and valve control into one
  • 30 ms response time for proportional valve control
  • Sampling rates 1000 times per second
  • Display screen verification of operations and parameters
  • IP66 and intrinsically safe saves on enclosure weight and purging needs

Applications and use cases

Efficient sample conditioning in an ethylene steam cracking

Ethylene diagram fullsize

Maintaining efficiency and safety in a steam-cracking operation depends on tight control across every stage. To simplify the system and strengthen performance, an integrator used Alicat’s intrinsically safe flow and pressure instruments throughout their analyzer sampling loop. With combined measurement and control in a single device, they reduced component count and provided digital communication directly to the plant’s control system.

Whether storing hydrocarbons, facilitating chemical reactions, or separating process streams, pressure vessels are central to the oil and gas industry. Incorporating IS‑Pro™ intrinsically safe pressure controllers into the pressure vessel control system can reduce safety risks, process inefficiencies, equipment damage, and regulatory non‑compliance.
