PF4

The new PF4 series is the latest development from ROTRONIC. The thermal measurement technique enables top-precision measurements in the smallest of spaces. This differential-pressure transmitter gives ROTRONIC customers a device to measure a further important parameter in addition to devices for humidity, temperature and CO2 measurement. With the optional temperature probe, the device is suitable for a wide range of applications. ROTRONIC stands for unparalleled accuracy and long-term stability. The new differential pressure series meets these requirements with a long-term stability of <0.3 %/year and an accuracy of ±1.0 % of full scale.

Applications The ROTRONIC differential-pressure transmitters are ideal for clean rooms, operating rooms and applications where even minor differences in pressure can have a big effect.

Features • High-precision measurement and long-term stability • Fast response time and low hysteresis • Analog signals freely configurable • Integrated relay switch contact • Large overload range • Selectable units • High immunity to dust and humidity in the medium
