The model CPG1000 precision digital pressure gauge takes the concept of an analogue gauge, and takes it to a level only matched by digital calibrators. The accuracy of digital measurement technology and the simplicity of an analogue gauge are brought together in the CPG1000, which in terms of performance, ease-of-use, and instrument features, is unmatched in the pressure measurement market.
The CPG1000 offers an accuracy of 0.05 % of the full scale value in 14 pressure ranges. It is temperature compensated between 0 ... 50 °C. Readings can be displayed in one of 21 standard units or also in customer-specific units, so that awkward conversions are avoided.
The measuring rate can be user-defined to match the type of measurement required. Standard applications usually use three measured values per second. If required, this rate can also be set to ten measured values per second. Via an energy-saving function, the CPG1000 switches automatically into “sleep” mode. With this, the battery life increases to up to 2,000 hours.
With the MIN/MAX function, the highest and lowest pressures that have been automatically recorded by the CPG1000 can be immediately retrieved. An automatic power-off function can be activated after a predefined time interval in order to extend battery life. The ZERO and TARE functions compensate for any sensor drift. Password protection for on-site calibration can be activated via the CPG1000 keypad. An RS-232 serial interface enables data for offline analysis to be read directly form the measuring instrument. An optional, external 24 V power supply input is available for the user, for when the CPG1000 is permanently built in to a process chain. The selectable damping function helps stabilise strongly-fluctuating pressures and makes them easier to read.
