The PT-104 platinum resistance data logger gives you the ultimate in resolution and accuracy. You can use it to measure temperature, voltage and resistance. You can connect to it directly using either USB or via ethernet over a computer network, or you can connect to it remotely using a modem. When the accuracy of your temperature measurements is paramount the PT-104 is what you need.

  • Measures temperature, resistance and voltage
  • High resolution and accuracy
  • No power supply required
  • USB and Ethernet (RJ45) interface
  • For use with PT100 and PT1000 sensors

Accuracy and Resolution
Although accurate temperature sensors are widely available, it has been difficult to take advantage of them due to errors caused by the measuring device. The PT104 however, is inherently accurate due to its novel design. Rather than relying on voltage references (which tend to be temperature sensitive) it uses 'reference' resistors which are extremely stable (low temperature co-efficient and drift). The exact value of each resistor is stored in an EEPROM to provide the ultimate in accuracy (yearly re-calibration is recommended). To achieve the 0.001 °C resolution a highly-advanced ADC is used that can resolve to better than 1 part in 16 million.

Temperature
The PT104 measures temperature using platinum resistance thermometers (PRTs). Both common industry standards (PT100 and PT1000) are supported. The unit is compatible with 2, 3 and 4 wire sensors (4 wire PT100 sensors are recommended for more accurate measurements, especially on longer lead lengths). We offer a wide range of PT-100 temperature sensors which are available for use with the PT-104.

Resistance
When measuring resistance, the unit uses a four-wire circuit to give the greatest possible accuracy.
Two resistance ranges are available (0 to 375 ohms and 0 to 10,000 ohms). The unit is calibrated for 0 to 375 ohms so this range should be used for accurate measurements.

Voltage
For voltage measurements, each input connector can be treated as a differential input with ground, or two single-ended inputs. Both inputs must be zero volts or above, though it does not matter which input has the higher voltage.
Two voltage ranges are available (0 to 115 mV and 0 to 2500 mV). For the most accurate measurements use the 0 to 2500 mV range.

Software
The PT-104 is supplied with PicoLog data logging software which can collect up to 1 million samples. PicoLog will automatically detect which sensor is connected and will display readings in the correct units. Also supplied is a software development kit. The SDK contains a range of software drivers and example code that you can use to write your own software or to use your PT-104 data logger with third party software. Features include:
  • Multiple views - view data as a graph, spreadsheet or text
  • Parameter scaling - convert raw data into standard engineering units
  • Math functions - use mathematical equations to calculate additional parameters
  • Alarm limits - program an alert if a parameter goes out of a specified range
  • IP networking - transfer measurements via a LAN or over the Internet
  • Full details on PicoLog
  • Software development kit includes drivers and example code for various programming languages including C, Excel and LabVIEW.


UKAS calibration is optionally available at extra cost, either of the unit on its own or with RTDs as a system. Please contact us for more details.
