2.5.9. 

Defining a Custom Sensor 

DaqLab enables the user to define custom sensors. This is a useful tool for when 

DaqPRO

 is 

communicating with many sensors from 

different vendors.  

Any additional sensor that you would like to connect to 

DaqPRO

 must comply with the following 

restrictions: 

•

 The 

sensor

’

s output must be either voltage in the range of 0 to 10V or current 

in the range of 4 to 24mA. 

•

 

The sensor Transfer Function (sensor output voltage changes vs. the sampled 
phenomenon changes) must be a linear Transfer Function. 

 

To define a new sensor: 

1. Connect 

DaqPRO

 to the PC. 

2. Click 

Logger

 on the menu bar, then click 

Define New Sensor

 to open the 

Define New Sensor

 

dialog box: 

 

Figure 22: Define New Sensor dialog box 

3. Click 

Add New Sensor

. 

4. Select 

a 

Based on

 option (depending on whether your sensor

’

s output is 0 to 10V or 4 to 

24mA). 

5.  Enter a sensor name and sensor unit. 
6.  Enter two calibration values (two real values and the corresponding output values of the 

sensor).
