Thermo Fisher Scientific and GE Druck have launched a new generation, high speed pressure controller that employs a unique, self-diagnostic digital control system developed and patented by the company.

The new DPI515 is the latest successor in GE Druck's DPI500 series. It combines advanced silicon sensor and intelligent digital control technologies with intuitive, user friendly software. This enables high productivity with improved accuracy and quality, also reducing downtime and maintenance.

Pressure ranges are available up to 210Bar gauge or absolute, offering precision up to 0.01% full scale.

Dual range versions of the device provide full independent channels, enabling any tow pressure ranges to be combined for even greater flexibility.

An optional barometric reference enables both gauge and absolute operation in addition to reading ambient pressure.

The DPI515 patented digital control system sets a new standard for controller performance with fast response, no overshoot and a setpoint stability better than 0.001% (10ppm) of full-scale pressure.

The low noise, wide bandwidth characteristic exhibits virtually unmeasurable pressure ripple at setpoint, automatically compensating for system leaks or thermal changes.

Fully programmable for high speed operation, the DPI515 has a long term stability better than 0.03% of reading per annum and requires just 2 or 3 re-calibration points. This means reduced cost of ownership and improved productivity.

This multi-purpose instrument enables quick and easy testing of pressure switches, leaks, pre-set pressures and cardinal points as a percentage of span of the units under test, in addition to storing bespoke test routines.

Suitable for bench top use or rack mounting, the DPI515 provides a choice of local or remote control via keypad or RS232/IEEE 488 interfaces.

Software drivers are available for LabVIEW, TestPoint or to emulate Druck DPI510, DPI520 or Ruska 7000 series controllers.
