Channel

Description

class tpg_256a_pressure_monitor.TPG_256A.Channel(gauge_number: int = None)

Simple container to hold channel information. The setup is read from the configuration file (e.g. label) or is retrieved from the controller directly (e.g. gauge_id).

The following gauge types are supported:

ID	Description
TPR	Pirani Gauge or Pirani Capacitive gauge
IKR9	Cold Cathode Gauge 10E-9
IKR11	Cold Cathode Gauge 10E-11
PKR	FullRange CC Gauge
PBR	FullRange BA Gauge
IMR	Pirani / High Pressure Gauge
CMR	Linear gauge
noSEn	No Sensor
no Sensor	No Sensor
noid	No identifier

The measurement status can take the following values:

Code	Status
0	Measurement data okay
1	Underrange
2	Overrange
3	Sensor error
4	Sensor off (IKR, PKR, IMR, PBR)
5	No sensor (output: 5,2.0000E-2 [mbar])
6	Identification error

Attributes

Channel.active	The gauge should be ON.
Channel.connected	The gauge was detected by the controller.
Channel.data	Latest pressure readout value.
Channel.gauge_id	Gauge type, retrieved from the controller.
Channel.gauge_number	The channel ID number.
Channel.label	Label of the gauge, to be used when logging to a database.
Channel.logging	Data from the gauge should be recorded.
Channel.status_code	Measurement status code.
Channel.status_str	Measurement status description.
