SEM315

The SEM315 is a DIN Rail temperature transmitter with HART Protocol. It accepts RTD, Thermocouple, mV and slidewire sensors. The SEM315 has full HART communications protocol which allows the user to quickly and easily down-load information or interrogate the device enabling the following:- Simple re-ranging of sensor type and range Easy on site re-calibration Self documentation Operation with proprietary software packages such as AMS Plant Web™ and Cornerstone™ Remote configuration on the (4 to 20) mA loop with a hand held communicator or with a PC & HART modem Online Digital communication concurrent with a (4 to 20) mA Analogue signal. All the standard HART universal and common usage commands are fully implemented, with other device specific commands that enable access to the enhanced performance parameters of the SEM315.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Some of the enhanced SEM315 features are as follows:

Sensor Referencing

The SEM315 sensor referencing via the Windows based MConfig software allows for close matching to a known reference sensor eliminating possible sensor errors.

User calibration

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

Custom Linearisation

The [X]*¹ facility allows the SEM315 to be programmed with a custom linearisation to suit non standard sensors or sensors with unusual or unique characteristics.

Sensor Burn out detection

If any sensor wire is broken or becomes disconnected the SEM315 output will automatically go to its user defined level (upscale or downscale). This happens irrespectively of which wire is broken.

Output current preset

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