We have newly developed the DPharp EJX series of pressure and differential pressure transmitters with the advanced silicon resonant sensor. The DPharp EJX. Differential Pressure transmitters compare two pressures and transmit the difference to a control unit. Differential Pressure transmitter have a limitless number of. Yokogawa gauge pressure solutions include traditional mount and in-line mount transmitters, all featuring Yokogawa DPharp technology to deliver accurate.

Managing two separate transmitter models is no longer necessary, reducing spares inventory and simplifying daily operations. The resonance frequencies of these resonators are represented by the following equation. Absolute Pressure transmitters compare a pressure relative to Absolute pressure. The EJX series is the world’s first series of differential pressure transmitters that can measure both differential and static pressures with just one sensor, as well as provide pressure readings and outputs.
P10 series can be used to measure not only differential pressure but also flow rate, liquid level, density and other process variables. There are several technologies on the market to measure mass flow. Accurate level readings are essential to the safe, reliable, profitable operation of your plant.
Capillary Fill Fluid Density Compensation. Pressure measurement is more than providing accurate and reliable data for process control. Let us review the features of the silicon resonant sensor, which are as follows: Boiler and Feedwater Pump Efficiency Optimization. Fully programmable, the indicator is customizable for your needs. Differential Pressure Transmitters use a reference point called the low-side pressure and compare it to the high-side pressure.
Highly Reliable Sensor The silicon resonant sensor used for the EJX series is stable because of its operating principle. Liquid Level transmitters measure differential pressure to infer the level in a vessel.
Figure 7 shows the step response characteristics of the most typical EJX differential pressure transmitter M capsule in the EJX series.

In order to realize a differential pressure transmitter that is immune to temperature effects and can perform stable measurement, focus was placed presdure the design effort to minimize the amount of fluid sealed in the pressure-receiving unit. Ultra Low-Copper Amplifier Housing. Ports in the instrument are marked high-side and low-side.
Yokogawa have been manufacturing electronic pressure transmitters for more than four decades. By making the most of the features of silicon resonators with a large gauge factor and by only processing signals from the two resonators, it is possible to obtain differential pressure and static pressure signals, which are more stable than those of piezoresistance-based sensors.
Interoperability and interchangeability can be ensured. Gauge Pressure transmitters compare a pressure relative to transmittter measure. Unlike other suppliers’ transmitters, the indicator is not driven off the 4 to 20mA analog signal, but, exist as a separate circuit allowing the display to operate independently from the output signal. Differential Pressure DP is defined as the difference between two pressures.
A Multi-Sensing transmitter combines transmitters for Differential Pressure, Gauge Pressure, and Temperature into one field instrument.
Yokogawa Pressure Transmitter LPS Overview
Absolute pressure is always a positive value. Of these capsules, the M, H and V capsules have a rangeability of 1: By employing the new overpressure protection mechanism, we have downsized the pressure-receiving unit so that it weighs only 2.
Overview Details Resources Videos News. Boiler and Feedwater Yyokogawa Efficiency Optimization. Gauge Pressure transmitters compare a pressure relative to atmospheric measure. One is yokogzwa Multi-variable Pressure Transmitter. Yokogawa offers a complete line of ISA compliant pressure transmitters.
New DPharp EJX Series Pressure And Differential Pressure Transmitters
Analog sensors can only measure DP and sensor temperature and therefore can only compensate for temperature effect. Improved performance can be attributed to the unique resonant silicon sensor design with dual resonators. Independent third-party verification With the rapid globalization of markets, numerous international standards and approvals are becoming necessary. Figure 12 shows input-output characteristics in the 0— kPa, 0—10 kPa and 0—1 kPa ranges.
Alarm Message Display In case of fault detection, the display shows a short message that provides information on the alarm in addition to the alarm number. Yokotawa multivariable transmitter already exists that measures differential and static pressures using multiple sensors. Other pressure sensor technologies require an analog to digital conversion before the signal can be processed, introducing additional errors.
A Multi-Sensing transmitter combines transmitters for Differential Prsesure, Gauge Pressure, and Temperature into one field instrument. When devices are initially installed, they operate at peak performance, but what happens after they are running under various process conditions and poorly managed or maintained?
