Pressure Transducers


The Pressure sensor measures-14.5 up to 10000 PSI when connected to a Dataq Instruments Data Acquisition product or Data Logger.

The pressure sensor allows Dataq Instruments data acquisition and data logger units to acquire oil, fuel, air, brake fluid (DOT3/DOT4) or water pressure (PSI) information. The combination of these two products provides a compact solution, with transducer excitation provided by the data logger. The logger itself allows data to be communicated to a connected PC over either a USB or Ethernet interface.

0.5-4.5V Output vs 4-20mA Output

  0.5-4.5 V Output 4-20mA Output
Power Consumption Very Low (0.05W)

For example, DI-2108 can power eight
High (max 25mA * Supply Voltage)

For example, DI-2008 can power only three.
Supply Voltage 5V, which is available on DI-2108, 2108P, 4108 and 4208 instruments, or
use AC adaptor 101099
8-30V, which is available on DI-2008 and DI-808, or
connect to car battery, use AC adaptor 101086
Cable Length Short Long
EMC Susceptibility Low High
Installation Connect signal and ground wires to input terminals directly Shunt resistor needs to be installed
Number of wires per transducer Three: Power, Ground, Signal Two: Power and Return
Live Zero Reading Yes. The minimum live signal is 0.5V Yes. The minimum live signal is 4mA

Not all pressure transducers are built the same

The diaphgram of pressure transducers can employ different material and technologies, and each one has its pros and cons. Here is the quick comparison table among the two types we offer
