High Pressure Electronic Reference Controller

HP ERC for pressure control above 3000 psi


HP ERC

Precision electronic reference pressure control up to 400 bar / 5800 psi

A high pressure electronic reference controller for applications using Equilibar® back pressure regulators above 200 bar(g) /3000 psig can be challenging to find. Our partners at Pressure Control Solutions in The Netherlands designed the new HP ERC to be used as an electronic reference controller in the range from 8 – 400 bar(g) /120 – 5800 psig. It can be used to control air or nitrogen pressure to the dome of the Equilibar back pressure regulator.

This 400 bar electronic pressure controller contains a PID controller with two proportional valves and an external pressure sensor. The HP ERC achieves incredibly stable pressure control without any overshoot.

  • For inert gas (N2, air)
  • Achieves a control stability of <0.1%
  • Minimal dead volume
  • Zero consumption of pressurized inert gas
  • Temperature range: -10°C to 70°C
  • Digital or analog communication options

Convenient Communication & Connections

The HP ERC standard configuration uses a 4-20mA analog signal but it can also be configured for 0 – 5 VDC, or 0-10VDC. Other custom communications can be configured such as DeviceNet, ProfiBus, ProfiNet, Ethercat, FlowBus, ModBusRTU, ModBusTCP/IP and CANopen.

It has a compression fittings that connect to the dome of the Equilibar BPR making it easy to automate in open or closed loop control.

There is a 700 bar version available for customers looking for extremely high pressure control.
