High performance dome-loaded pressure regulator set for inline installation, combined with high-tech sensor technology and electronic components. The dome pressure regulator 747LE/S SMART can signal, for example, pressures, temperatures and an indication of the flow rate. These signals can be used to optimize performance, safety and maintenance regimes.

WITT dome pressure regulator technology is unique in the world as it offers maximum pressure constancy even at high and fluctuating flow rates or with small differences between inlet and outlet pressure. Now the dome pressure regulator 747LE/S is also available with smart functions: Important operating parameters can be displayed via 4-20 mA signals, enabling the gas supply to be monitored and optimised. Continuous data logging enables quality control and is an important step towards networked production.


Features of WITT dome pressure regulator technology

The extraordinary pressure constancy of WITT dome pressure regulators is the result of a complex technology consisting of perfectly matched components:

  • Pilot Control Tube (PCT): One of the features enabling highly accurate control of outlet pressure
  • Balanced Seat Design (BSD): Further enabling control precision, high reliability and low maintenance
  • A complete solution, ready to use: With integrated pilot pressure regulator, completely assembled and tested
  • Own-medium controlled: Enabling autonomous operation (no separate gas supply required)
  • Closed system: Self-relieving design, but no gas is released to atmosphere


Smart Features

In the smart dome pressure regulator, temperature and pressure values are captured by high-tech sensors and transmitted via 4-20 mA signals. Depending on customer requirements, the following features are available individually or combined:

  • Signaling and display of inlet pressure (P1) and outlet pressure (P2) in bar and temperature (T1 and T2) in °C
  • Signaling and display of the pilot pressure (P3)
  • Indication of the instantaneous gas flow rate (FR) in Nm³/h
