RTDType
Specify sensor sensitivity
Description
Use this property to specify the sensitivity of a standard RTD sensor in the session-based interface. A standard RTD sensor is defined as a 100–ohm platinum sensor.
When you create an RTD channel, the sensitivity is unknown and
the RTDType
property displays Unknown
.
You must change this to one of these valid values:
Pt3750
Pt3851
Pt3911
Pt3916
Pt3920
Pt3928
Example
Set RTD Sensor Type
Set an RTD sensor’s sensitivity type.
Create a session and add an RTD channel.
s = daq.createSession('ni'); ch = addAnalogInputChannel(s,'cDAQ1Mod7',3, 'RTD');
Set the RTDType
to Pt3851
.
ch.RTDType = 'Pt3851'
ch = Data acquisition analog input RTD channel 'ai3' on device 'cDAQ1Mod7': Units: Celsius RTDType: Pt3851 RTDConfiguration: ThreeWire R0: 'Unknown' ExcitationCurrent: 0.0005 ExcitationSource: Internal Coupling: DC TerminalConfig: Differential Range: -200 to +660 Celsius Name: '' ID: 'ai3' Device: [1x1 daq.ni.CompactDAQModule] MeasurementType: 'RTD' ADCTimingMode: HighResolution
