CPB5000 balances incorporate a piston and cylinder made of tungsten carbide, which is renowned for its small temperature coefficient.
Pressure balances have been used in calibration laboratories of industry, national institutes and research laboratories for many years but few offer the versatility and scope of the CPB5000.
Its piston cylinder assembly enables the user to set up a compact system at a favourable price.
It be used as a reference instrument for testing and calibrating instruments in controlled environments such as factories and laboratories.
Due to its fully integrated pressure generation and purely mechanical measuring principles it is also suited to on-site testing.
This collection of dead weight testers covers a pressure range of up to 100bar pneumatic, 4000bar hydraulic and does it with an accuracy of up to 0.008%.
They are available with a variety of measuring media and each balance can be virtually tailored made to suit specific needs and certified with a calibration certificate.
Accuracy of a pressure balance is not just defined by its specified value; it also depends on the quality of the materials that make it and by the workmanship of its system.
The CPB5000 balances incorporate a piston and cylinder made of tungsten carbide, which is renowned for its small temperature coefficient and it is this combined with excellent craftsmanship and several refinement processes that ensure a superior quality finish offering prolonged and superior spin and float times.
Measuring ranges can be changed quickly and easily without the use of tools.
The piston cylinder can literally be changed with a twist of the wrist for one of a different effective area and using the same mass set.
This gives the user great flexibility.
All masses come housed in robust wooden boxes and, protected in this way, there is no danger of scratching or damaging their integrity.
The CPU5000 calibration interface is also available, performing all the complicated mathematical calculations for the user.
All critical ambient parameters are registered and automatically corrected in real-time and the user is told exactly what masses are needed and can fit in to any existing system.
This presents the ability for true pressure to be calculated, generated and displayed in real time, with transfer to PC available.
It is the combination of these two devices that offers the user extreme flexibility, ease of use and reliable and accurate calibrations, and all at a highly attractive performance to price ratio.
