Product Files

The SEM710 is  a new generation head mounted temperature transmitter with a built in temperature display. Ideal for indicating the process value at the point of measurement.

Its universal input has been designed to accept most common RTD and thermocouple sensor inputs and provide the user with a standard two wire (4 to 20) mA output signal. Isolation is provided between input and output and all temperature ranges are linear to temperature. The addition of a display provides the user with instant information of the loop condition at the point of measurement. It comes in either our SCH4 ABS plastic connector head or our new SCH15 Stainless steel connector head. Both of which are available in snenor or wall mount versions.

Designed for ease of use, our latest USB interface is fitted for quick and easy configuration. Just connect a standard USB cable between the SEM710 and your PC. Using our free configuration software, your PC will automatically upload the existing configuration data and guide you through any changes you wish to make. To further help save time, the SEM710 does not need to be wired to a power supply during the configuration process, it is powered via the USB interface from your PC.

Features:

  • Pt100 or Thermocouple Input
  • Isolated
  • 4 Digit LED Display
  • Housing ABS plastic or stainless steel
