## **INTRODUCTION** 

The SEM310 is a HART 5 upwards, (generic device) compatible universal transmitter. It accepts RTD, Thermocouple, Potentiometer or millivolt input signals and converts them to the industry standard (4 to 20) mA transmission signal. Alternatively, HART multidrop mode can be selected. 

The SEM310 is programmed using a standard USB lead. The ATEX / UKEX / IECEx version (SEM310X)  is programmed with a ATEX / UKEX / IECEx approved communication lead (USBX Config). 

Both versions use our free configuration USBSpeedlink software downloaded from our web site. Standard features can also be programmed using HART communication. 

## **FEATURE HIGHLIGHTS** 

## **SENSOR REFERENCING** 

The SEM310 sensor referencing via the Windows based USBSpeedlink software allows for close matching to a known reference sensor eliminating possible sensor errors. 

## **USER CALIBRATION** 

In addition to sensor referencing, current output trimming is possible via the USB and HART commands. 

## **CUSTOM LINEARISATION** 

The SEM310 can be programmed with a custom linearization to suit nonstandard sensors or sensors with unusual or unique characteristics. Consult the sales office for details. 

## **SENSOR BURN OUT DETECTION** 

If a sensor wire is broken or becomes disconnected the SEM310 output will automatically go to its user defined level (upscale or downscale) or pre-set value. 

## **OUTPUT CURRENT PRESET** 

For ease of system calibration and commissioning the output can be set to a pre-defined level anywhere within the (4 to 20) mA range.
