Compact, lightweight, intuitive and intelligent, Yokogawa pressure instruments simplify all aspects of handling, commissioning, installation, operation, and maintenance while delivering outstanding performance.

Differential Pressure

Digital Remote Sensor DRS Transmitter connects two pressure sensors, master high pressure side and slave low pressure side in a remote location, with DRS dedicated communication cable to measure differential pressure.

Click ‘Details’ above to see the following content. The output is transmitted to a control system. Figure 7 shows the step response characteristics of the most typical EJX differential pressure transmitter M capsule in the EJX series.

Differential Pressure DP is defined as the difference between two pressures. The resonance frequency can be yokogaawa directly using a counter for CPU-based high-precision data processing.

Overview Details Resources Videos News. Moreover, the silicon resonant sensor featuring long-term stability further enhances the transmitter quality and reliability that have already been demonstrated by the industry-proven EJA series.


Given these three pieces of process data, our differential pressure transmitters compensate the DP measurement for temperature effect and static pressure effect in real time. P10 series can be used to measure not only differential pressure but also flow rate, liquid level, density and other process variables. As a result, users can quickly know the contents of the alarm from the short message without checking any document for the alarm number.

Yokogswa pressure-receiving unit features a symmetrical structure resistant to the effects of various external pressure disturbances. The selected values will then be cycled through on the display.

The EJX series has some programs to verify microprocessor operation. Absolute pressure transmittef always a positive value. Figure 15 shows the effects of overpressure. Refer to the General Specification sheet located under the ‘Downloads’ tab for detailed specifications.

Yokogawa have been manufacturing electronic pressure transmitters for more than four decades.

Yokogawa Pressure Transmitter LPS Overview

Liquid Level transmitters measure differential pressure to infer the level in a vessel. The output is transmitted to a control system. Hydrogen is the simplest and smallest atomic element. As you gain experience with these transmitters, the interval between calibration checks is extended. Managing two separate transmitter models is no longer necessary, reducing spares inventory and simplifying daily operations.

Do more with less Pressure measurement is more than providing accurate and reliable data for process control. Thanks to the enhanced flexibility in model selection and the added transmitter functionality, the EJX series has the excellent capability to meet the need for versatile applications, further contributing to minimizing customers’ total cost of ownership TCO.


The resonance frequency calculation is simplified here into the following equation for ease of explanation. The new overpressure protection mechanism that has been adopted for the EJX series is illustrated in Figure 5. Absolute Pressure transmitters compare a pressure relative to Absolute pressure. In consideration of the importance pressurf ease of perception, the built-in display has been enlarged while the EJX series as a whole has been downsized Figure If the reference clock is excessively speeded up, the current consumption will increase, thus failing to satisfy the product specifications.

The transmission unit consists of a electronic unit and a terminal box, which can be used for every model in the EJX series. trxnsmitter

Low Power Pressure Transmitter. Highly Reliable Sensor The silicon resonant sensor prezsure for the EJX series is stable because of its operating principle. Differential pressure DP flow measurement is a well-known and common technology for measuring flow in a closed pipe.

By combining the function with software that takes advantage of these applications, it is possible to execute advanced diagnoses such as impulse line blocking diagnosis.
