SEM1801/2 XTC

UKEX, ATEX, IECEx rail temperature transmitter for thermocouple sensors

The SEM1801 / 2 XTC intrinsically safe temperature transmitter accepts thermocouple temperature sensors and converts the sensor output over a configured range to a standard industrial (4 to 20) mA transmission signal. For use in hazardous areas, two versions are available: single or dual channel.  The product is UKEX, ATEX and IECEx approved for hazardous areas.

PC configuration allows the user to select TC type, range, filter, units, linearisation and burnout direction, without requiring calibration equipment. Additionally, the user may read live process data when connected to the PC (in the safe area), 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 (0 to 1000) °C type K
burnout high and filter off.

INTRINSICALLY SAFE TRANSMITTER HIGHLIGHTS

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

THERMOCOUPLE TYPES
As standard the SEM1801/2TXC has all common thermocouple sensors available from its software library
with extra sensors available.

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

STABILITY
The SEM1801/2TCX transmitter incorporates the latest digital technology to ensure accurate, low drift
performance.
