Status SEM320/55 HART Field Transmitter

• Hart 5,6,7 compatible
• Process value, text and bar-graph displays
• Dual inputs with maths functions
• (4 to 20) ma or hart multidrop output

The SEM320 is a HART (generic device) field temperature transmitter that is HART 5,6,7 compatible, universal temperature transmitter with display. 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.

Housed in its own bespoke connection head, it is programmed using a communication lead (USB Config) together with our free configuration USBSpeedlink software. Standard HART features can also be programmed using HART communication.

The HART field temperature transmitter has a rotational five-digit display for the process value and a 5-digit display for messaging, in addition to a bar graph for % of mA output.

Is is used together with our temperature probes. We can manufacture these to your specification. The most popular types can be seen here

SENSOR-REFERENCING

The SEM320 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 SEM320 can be programmed with a custom linearisation to suit non-standard 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 SEM320 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.
