Status SEM1801XR - Single Channel Temperature Transmitter for RTD or Slidewire Sensors. ATEX and IECEx Approved

• ATEX AND IECEx APPROVED
• MULTIPLE RTD INPUT TYPES
• SINGLE CHANNEL VERSION
• RAIL MOUNT (4 to 20) mA TRANSMITTER
• SENSOR OFFSET, ADJUSTABLE INPUT FILTER

The SEM1801XR ‘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. 

If required, the desired range can be specified at the time of order, removing the need for user configuration. If the range is not specified then the transmitter will be shipped with the default range of Pt100 (0 to 100) °C, burnout high and filter off.

FEATURE HIGHLIGHTS

SENSOR REFERENCING (Temperature mode)
The SEM1801XR sensor referencing via the Windows based USBSpeedlink software allows for close matching to a known reference sensor eliminating possible sensor errors.

Product configuration software

CUSTOM LINEARISATION
As standard the SEM1801XR has all common RTD sensors available from its software library. Additionally, the SEM1801XR 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 SEM1801XR output will automatically go to its user defined level (upscale or downscale) or a pre-set value.

STABILITY
The SEM1801XR rail mount transmitter incorporates the latest digital technology to ensure accurate, low drift performance.
