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:
  • 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.
