ISA100 wireless pressure transmitters

概述:

ISA100 wireless temperature and pressure transmitters.

概述:
  • Daily manual reading of pressure and temperature gauges with report by phone.
  • The customer wants to change measurement from off-line to on-line.
  • Cabling for wired transmitters in huge plants (up to 300 meters long) is expensive.
概述:

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.

行业:
概述:
  • Wireless pressure and temperature monitoring.
  • Repeater was set under the gateway.
  • The maximum distance between the repeater and transmitters is approximately 500m.
概述:

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.
概述:

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.

概述:
  • Temperature Transmitter (YTA) and Pressure Transmitter (EJX) are installed at each monitoring point.
  • Repeater is installed on high position.
