Yokogawa announces low-power DPharp EJA-E DP transmitter

October 29, 2014 - Yokogawa Electric announces a low-power version of the DPharp EJA-E series differential pressure/pressure transmitter. This 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.

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

2. Superior accuracy and stability
Like all DPharp transmitters, this 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 DPharp transmitter can be done easily using a setting switch and an external adjustment screw on the transmitter.

Major Target Markets
Process industries such as oil and natural gas, petrochemicals, chemicals, iron and steel, pulp and paper, power, and water treatment

Applications
Measurement of pressure and flow rate of liquid, gas, and steam; measurement of liquid level
