ISA100 wireless temperature and pressure transmitters.

摘要:
  • 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.
產業別:
摘要:

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.

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