SEM310 Temperature Transmitter

Brand: Status Instruments

The SEM310 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 and Cornerstone
  • Remote configuration on the 4-20 mA loop with a hand held communicator or with a PC and HART modem
  • Online digital communication concurrent with a 4-20 mA Analog signal
