Special Features

• High level of accuracy
• Little zero point drift or hysteresis; largely independent of temperature
• LCD display (optional)
• Output signal: 0 .. 10 V (PU), 0/4 .. 20 mA (PI)
• Factory-adjusted attenuation of the output signal of up to 5 s possible (optional)
• Can be calibrated

These differential pressure transmitters are available in a wide range of precision classes and therefore suitable for applications in the heating, air-conditioning and ventilation industries as well as sophisticated laboratory applications. An optional display allows measurement values to be read directly on-site in Pa, kPa or mmH 2 O. An optional time constant (up to 5s) allows the instrument to generate an attenuated output signal, even under fluctuating pressure conditions.

Options

• Available with an factory calibration certificate or calibration certificate according to DKD-R 6-1 (optional).
