Differential pressure transmitters

Differential

Differential pressure transmitters are devices used to measure the pressure difference between two reference points.

Working Principle

Differential pressure transmitters are designed to provide precise and reliable measurements, utilizing advanced electronic sensing techniques. They operate by measuring the input pressure from two distinct points and providing an output signal proportional to the detected pressure difference.

Applications

These devices find applications in a wide range of industrial settings, including fluid level monitoring in tanks, detection of air and gas flows, HVAC systems, as well as complex industrial control processes.

Design Thanks to their advanced capabilities, differential pressure transmitters can provide accurate measurements even in harsh environmental conditions or potentially corrosive environments.

Moreover, their compactness and ease of installation make them indispensable tools for monitoring and controlling industrial processes, enhancing operational efficiency and safety.

In conclusion, differential pressure transmitters are versatile and reliable instruments used in various industries to obtain precise measurements of pressure difference. Their cutting-edge design makes them essential for improving the performance and reliability of industrial processes.

Ideal for HVAC (Heating, Ventilation and Air Conditioning), clean-room and flow measurement applications, the NP785 is an ultra low differential pressure transmitter for measuring very small over-pressure, underpressure and differential pressure in neutral, non-corrosive gaseous media. It provides a pressure proportional linear signal output with configurable measuring range via USB using the configuration software.
NP785 can operate bi-directionally, providing the ability to measure differential pressure ranges from vacuum to positive pressure. It is housed in a DIN rail mountable ABS/ PC enclosure and its nickel plated brass fittings accept pneumatic hoses with 4 or 6 mm internal diameter.
The analog output can be set to either 0-10 V or 4-20 mA while having an RS485 with Modbus RTU communication protocol. Designed for HVAC and industrial environment, the NP785 ensures temperature compensation for longterm stability and complies with EMC standards, providing robustness and reliability for a wide range of applications.
