01 / OVERVIEW

ภาพรวม

The SEM1801/2XR ‘smart’ transmitter is designed for use with RTD or Slidewire sensors and converts the sensor signal into an industry standard (4 to 20) mA loop powered output.

PC configuration (in the safe area) allows the user to select sensor type, range, filter, tag, units and error signal without requiring calibration equipment. Additionally, the user may read live process data when connected to the PC: this allows for sensor offset, and output alignment calibration, where the user can enter values to match the actual process, therefore reducing system errors.

02 / FEATURES

คุณสมบัติเด่น

Sensor Referencing (Temperature mode)

The SEM1801/2XR sensor referencing via the Windows based USBSpeedlink software allows for close matching to a known reference sensor eliminating possible sensor errors.

Custom Linearisation

As standard the SEM1801/2XR has all common RTD sensors available from its software library. Additionally, the SEM1801/2XR can be programmed with up to 22-point custom linearization for ohms and slidewire inputs.

Sensor Burn Out Detection (Temperature mode)

If a sensor wire is broken or becomes disconnected the SEM1801/2XR output will automatically go to its user defined level (upscale or downscale) or a pre-set value.
