Yokogawa Targets Upstream Oil and Gas Applications with Release of New Low-Power Differential Pressure/Pressure Transmitters

Yokogawa Electric Corporation announced that it has developed a new low-power version of the DPharp EJA-E series differential pressure/pressure transmitter and will release this product in all markets other than Japan and Europe on December 15. The European release will follow in 2015. This new low-power product outputs both 1 to 5 V DC and HART signals and has been developed to meet the specific requirements of oil and gas exploration and production (upstream) applications.

Differential pressure/pressure transmitters are widely used in the oil, petrochemical, and chemical industries to measure the pressure, flow rate, and level of liquid, gas, and steam. They can be found both in plants and in the field, at locations, such as oil and gas wells.

Thanks to the global rise in demand for energy, oil and gas resources are being actively developed. As technological progress in recent years has made it possible to develop and produce oil and gas in places with poor infrastructure (such as electricity and communications), instruments and devices in such areas must be able to function on a limited power supply from solar power or batteries.

New Product features include:

1. High energy efficiency

   Thanks to a redesign of its power circuitry, this new low-power DPharp EJA-E series transmitter achieves high energy efficiency, consuming just 27 mW (0.96 to 3 mA) of power.

2. High accuracy and stability

   Like all DPharp transmitters, this new low-power model is both highly accurate and stable. It has a reference accuracy of ±0.055% and will remain within ±0.1% of the upper range limit for seven years. In these respects, this new product outperforms most other generally available low-power models with equivalent specifications.

3. Easy installation and maintenance

   Basic settings for this new DPharp transmitter can be done easily using a setting switch and an external adjustment screw on the transmitter.
