What Is a Wireless Differential Pressure Transmitter?
High performance wireless differential pressure transmitters measure liquid, gas, or steam flow as well as liquid level, density, and pressure. These transmitters transmit not only process variables but also the setting parameters using wireless signal.
Yokogawa's EJX-B series transmitters combine the features on our thoroughbred EJX-A series with ISA100 wireless communication to deliver new opportunities and possibilities.
All Yokogawa ISA100 compliant products can integrate into any ISA100 compliant network.

ISA100 wireless temperature and pressure transmitters.
Eliminating the wire using wireless transmitter is the perfect solution for rotating equipment. It establishes data collection between the transmitter and the gateway by reliable communication even though the dryer was rotating.
ISA100 wireless temperature and pressure transmitters with orifice plates allow:
- No cabling installations or maintenance.
- Small amount of hardware and simple equipment implementation means minimizing potential vandalism.
ISA100 Wireless Monitoring
- Gateway x1, Temperature Transmitter (YTA) x3, Pressure Transmitter (EJX) x1, Repeater x1
Gateway is installed at control room and 3m height extended antenna is set.
- Temperature Transmitter (YTA) and Pressure Transmitter (EJX) are installed at each monitoring point.
- Repeater is installed on high position.
- Oil level measurement of diesel tanks that feed fuel to their diesel generator's which are at three locations and 400 meters apart from each other.
- Also to measure level , pressure and flow to and from their main storage yard.
