lauda

Lauda class for Lauda chillers.

Classes

Lauda(*args, **kwargs)

SCPIInstrument implementation for Lauda chillers.

Lauda

class icicle.lauda.Lauda(*args, **kwargs)

Bases: SCPIInstrument

SCPIInstrument implementation for Lauda chillers.

This class has been developed using the documentation for Lauda Eco Gold thermostats and tested using a Lauda Proline Kryomat RP 3090 CW chiller. This should work for other Lauda thermostats and chillers too.

__init__(resource='ASRL11::INSTR', sim=False)

Parameters:: resource – VISA Resource address. See VISA docs for more info.

BAUD_RATE = 9600: Serial link Baud rate.

COM_RESET = '': Instrument Reset SCPI command.

MEASURE_COMMAND_MAP = {'TEMP:BATH': 'TEMPERATURE_BATH', 'TEMP:EXT': 'TEMPERATURE_EXTERNAL'}

MEASURE_TYPES = {'TEMP:BATH': 'Bath Temperature (°C)', 'TEMP:EXT': 'Ext Temperature (°C)'}: Measurement types for the Lauda chiller.

class MeasureChannel(instrument, channel, measure_type, unit='')

Bases: MeasureChannel

MeasureChannel implementation for Lauda chillers.

property status

Returns:: Diagnostics returned by STAT query.

property value

Performs measurement and returns value.

Returns:: measured value.
Return type:: float

READ_TERMINATION = '\r\n': Read termination characters.

TIMEOUT = 10000: Serial link timeout.

WRITE_TERMINATION = '\r\n': Write termination characters.

validate_channel(channel, raise_exception=True)

Check if an channel exists on this device. Only successful if channel == 1.

Parameters:: channel – Channel number to validate as an input
