Applications

• Mobile calibration of low pressure instruments
• Flexible and accurate measurement of very low gauge pressures or differential pressures
• Generation of very low pressures

Special Features

• Pressure ranges from 2 mbar up to 1,000 mbar gauge pressure and differential pressure
• 0.2 % total uncertainty
• Internal pressure generation (hand-operated)
• Portable with battery operation
• Second pressure range with factor 1/5 turn-down

Areas of application

The instrument has mainly been designed for HVAC, filtering, dedusting, clean room and medical technology applications. It is used for calibrations and accurate measurements.

Functionality

The CPC 2090 is a pressure calibrator incorporating an integrated pressure generator and pressure reference both for battery and mains operation. Pressure build-up is done using a hand pump. For fine adjustment metal bellows are used.

The internal pressure sensor is exclusively suitable for dry, clean and non-aggressive gases. By pressing a specific button the measurement range can be changed by factor 1/5 and via another button the response time of the instrument can be set.

On request the instrument can be supplied with a factory, DKD or other equivalent calibration certificate.

The pressure is measured via a sensitive diaphragm, which is adapted to the pressure range. An inductive system generates a linear signal which changes in proportion to the prevailing pressure.
