SEM315 Temperature Transmitter

Brand: Status Instruments

The SEM315 has the HART communications protocol which allows the user to quickly and easily down-load information or interrogate the device enabling the following:
  • Simple re-ranging of sensor type and range
  • Easy on site re-calibration
  • Operation with proprietary software packages such as AMS Plant Web TM and Cornerstone TM
  • Remote configuration on the (4-20) mA loop with a hand held communicator or with a PC & HART modem
  • Online Digital communication concurrent with a (4-20) mA Analog signal
