PK 15

Differential-pressure transducer with limit contact.

In addition to differential pressure, the differential-pressure transducer PK 15 also records positive and negative overpressure. The central unit is a pressure cell with a diaphragm spring made of beryllium bronze which, in accordance with the pressure difference, is displaced between two chambers. The displacement is measured, without making contact, via an inductive displacement recorder. The device does not contain any components that can rub against each other or parts subject to mechanical wear. The device is mainly suitable for use in air-conditioning and ventilation units, for monitoring filling levels, for filter control, etc.

The 3 or 4-figure LC display is available as an option.
In addition to Pa and kPa, it can also display mmWs etc.

An optional time constant of up to 5 s (only pressure transducer) means the device can also be used under fluctuating pressure conditions and generates a stabilised output signal.

Technical data:
Measuring ranges:
± 50 Pa to ± 100 kPa
Linearity: ± 1 %,
optional ± 0.5 ± 0.2 %
Output signals:
0-10 V, 0-20 mA, 4-20 mA
Supply voltages:
24 VAC, 24 VDC, 230 VAC
Time constants: 20 ms, 1,2,5 s
Medium: air, all non-aggressive gases
