Differential Pressure Standards - Metrological Standards - 5500

Designed for use as a differential pressure primary standard, the 5500 series can also be used as a high pressure pneumatic primary standard. This dual function capability effectively provides the user with two genuine primary standards in one instrument.

Specification

• 2kPa to 78 MPa. Differential Pressure Range
• Static pressure range to 80 MPa
• Accuracy up to 0.005% of reading on Differential Pressure
• Floating times exceeding 20 minutes up to maximum pressure
• Operation on any gas, inducing methane and natural gas - flameproof versions available
• Oil lubricated Pistons provide long float times and reduce piston cleaning requirements

Differential Pressure Standards – Metrological Standards - 1500 & 1600

Differential Pressure transmitters provide critical profit or safety-related information in processes like fiscal flow metering. Model 1500 and 1600 dividers enable their calibration under real working conditions and therefore bring improved process control.
The novel approach of the divider system allows the user to generate stable differential pressures very quickly, thereby reducing calibration times dramatically. The divider is a robust and easy-to-use system which can generate extremely accurate differential pressures, at high static pressures, with the minimum of operator experience.

Specification

• 0 to 1 MPa Differential Pressure range.
• Static pressure range to 40 MPa.
• Accuracy ≤0.005% of reading on DP Measurements with no effects from static pressure.
• The model 1600 can be used with a Vacuum pump to measure differential pressure where the static pressure is less than the atmospheric pressure.

• Static pressure range to 20 MPa
• Static Pressure Accuracy ≤0.01% of reading
• Differential Pressure accuracy ≤0.03% of reading + 0.2 mbar
• Oil lubricated Pistons provide long float times and reduce piston cleaning requirements
