In this Tech Article from CAS DataLoggers and dataTaker, we describe the process of connecting the Druck PTX 1830 depth/level sensor to a dataTaker DT8x series data logger. This sensor outputs a 4-20mA signal and will be powered by the dataTaker’s switchable 12V regulated voltage output.
- Equipment required:
- dataTaker DT8x data logger
- Druck PTX 1830 depth sensor
- Connecting the sensor:
Connect the wires from the sensor to the datalogger as follows:
- Red Wire–12V terminal
- Blue Wire—Channel 1 # terminal
- Connect a wire between DGND and EXT# terminals
- Taking Measurements:
The basic measurement outputs a scaled output. Using the built-in dataTaker dEX software, the code is as simple as this:
S1=0,10″m” ‘scale a 4-20mA reading to a 0-10m value
1SSPWR=1 ‘turn on the 12V output
1#L(“depth~m”,S1) ‘sample, scale and log depth
The full dataTaker dEX program samples the sensor once per hour and stores it to the datalogger internal memory.
‘Sample program Level sensor PTX 1830 (4-20mA)
‘Sampling period: 1 sample / hour
S1=0,10″m” ‘set scale of 4-20mA sensor
‘ Schedule A
‘ – Logs to the internal memory (B:)
‘ – Logs up to 3MB of data records, overwrites when full
‘ – Runs every 1 hour
‘control power and sample from the sensor
1SSPWR(W)=1 1#L(“2-Minute Depth~m”,S1,MD5000,FF3) 1SSPWR(W)=0
DataTaker Series 3 Loggers:
The world-renowned dataTaker Series 3 Dataloggers can connect to nearly every sensor type, scaling and logging almost any physical value including Temperature, Voltage/Current, 4-20mA loops, Resistance, Strain gauges, Frequency, and more. They also provide a wide array of communications features including RS232 with modem support, USB, Ethernet, and USB memory stick ports.
DataTaker’s dEX software is preinstalled with all dataTaker dataloggers and has a Windows Explorer-style graphical interface allowing quick setup and configuration of the logger. This software is configured and run directly from a web browser enabling access either locally or remotely over the Internet. Operators can use any of the logger’s built-in communications ports to view dEX, including Ethernet, USB and RS-232.
