The high performance wireless differential pressure transmitter EJX110B features a single crystal silicon resonant sensor and is suitable to measure liquid, gas, or steam flow as well as liquid level, density, and pressure.

Wireless diaphragm seals are used to prevent process medium from entering directly into the pressure-sensing assembly of the differential pressure and pressure transmitters, they are connected to the transmitter using capillaries filled with fill fluid.

The high performance wireless flange mounted differential pressure transmitter EJX210B features a single crystal silicon resonant sensor and is suitable to measure levels of densities of solidifying or precipitating liquids.

The high performance wireless pressure transmitter EJX310B features a single crystal silicon resonant sensor and are suitable to measure liquid, gas, or steam flow as well as liquid level, density, and pressure.

The high performance wireless guage pressure transmitter EJX430B features a single crystal silicon resonant sensor and are suitable to measure liquid, gas, or steam flow as well as liquid level, density, and pressure.

Wireless diaphragm seals are used to prevent process medium from entering directly into the pressure-sensing assembly of the differential pressure and pressure transmitters, they are connected to the transmitter using capillaries filled with fill fluid.

The high performance wireless absolute and gauge pressure transmitters EJX510B and EJX530B feature single crystal silicon resonant sensor and are suitable to measure liquid, gas, or steam pressure.

The high performance wireless absolute and gauge pressure transmitters EJX510B and EJX530B feature single crystal silicon resonant sensor and are suitable to measure liquid, gas, or steam pressure.

YFGW410 Field Wireless Management Station has system manager/security manager/gateway function based on ISA100.11a, and combining this with Field Wireless Access Point(YFGW510) and/or Field Wireless Media Converter(YFGW610) composes the field wireless system.

YFGW520 Field Wireless Access Poin has backbone router function based on ISA, and combining this with Field Wireless Management Station (YFGW410) and/or Field Wireless Media Converter (YFGW610) composes the field wireless system.

YFGW710 Field Wireless Integrated Gateway comply to the wireless communications standard ISA100.11a for industrial automation of International Society of Automation (ISA), and relays ISA100 Device data to the system via integrated backbone router. Single unit of YFGW710 has integrated functions of backbone router, system manager, security manage, and gateway.

The high performance temperature transmitter YTA510 accepts Thermocouple, RTD, ohms or DC mill volt inputs. The transmitters transmit not only process variables but also the setting parameters using wireless signal. The transmitters run on internal batteries, and the installation cost can be decreased since hard-wiring is not required. The communication is based on ISA100.11a protocol specifications. 

The flexibility of wireless solutions enables less investment in infrastructure while providing greater insights into plant operations.

Yokogawa offers a complete line of ISA100 compliant pressure transmitters. The line includes transmitters that can measure differential pressure, absolute pressure, and gauge pressure.
