The excellent performance and ease of application of the P10 series have been proven in numerous installations in every kind of process industry throughout the world. P10 series can be used to measure not only differential pressure but also flow rate, liquid level, density and other process variables which can be measured via differential pressure, converting them to 20 to 100 kPa (0.2 to 1.0kg/c㎡, 0.2 to 1.0 bar or 3 to 15 psi) signals for transmission to remote receivers.
Differential pressure transmitters are employed in many fields, often under very severe working conditions that pose many technical problems. The P10 series is the ultimate in transmitters, solving these problems ingeniously.

YTA Series temperature transmitters convert the sensor signals to a unified signal, 4 to 20mA signal or FOUNDATIONâ„¢ fieldbus. This eliminates the drawbacks of wire resistance and signal noise that are often experienced with conventional temperature instruments, which must be connected by long extension lead wires or three-conductor cables to converters in an instrument panel room.
