High-end precision pressure controller Model APK

Electronic controllers are pressure standards with innovative technologies for automatic pressure control and precision pressure measurement.

The implementation of modern know-how in the manufacture of high-precision pressure sensors allows the use of APK pressure calibrator as a working pressure reference in the production of all types of industrial measuring instruments and pressure calibrators with the possibility of increasing their measurement accuracy up to 0,01% FS.

Due to the wide variations possibilities, Model APK Model is also suitable for various service laboratories in production facilities, product quality assurance laboratories, research laboratories and national metrological institutes.

Advantages
Automatic control and precision measurement of pressure in ranges from 2.5 kPa up to 42 MPa.

Up to 3 integrated, interchangeable reference pressure sensors.

Sensors with absolute, gauge or bi-directional ranges:
Gauge FS: 2.5 kPa…42 MPa,
Absolute FS: 40 kPa…42.1 MPa,
Bi-directional: from -2.5…2.5 kPa up to -0.1…42 MPa.

Extended uncertainty up to 0.01%.

Control stability up to ±0.005%.

Control from a multi-functional and multi-language touch screen or remotely via a PC (USB, RS-232, Ethernet).

An open protocol and a standard set of commands for the possibility of writing custom software for production line of process transmitters.

Low noise when working at high pressures, due to the use of innovative pressure control technologies.

Compact design, desktop version or for mounting in a 19" rack.

Work only on dry clean gas or nitrogen.

Powered by a single-phase 220V/50 Hz network. Power consumption is less than 2 kW.
