The PT-104 is a 4-channel temperature measuring data logger. It offers the ultimate in resolution (0.001 °C) and accuracy (0.01 °C). Along with temperature it can also be used to measure resistance and voltage.
PT-104 Platinum Resistance Data Logger
- Measures temperature, resistance and voltage
- High resolution and accuracy
- Works with PT100 and PT1000 sensors
- Supports 2,3 and 4-wire sensors
- No power supply required
- USB and Ethernet interfaces
- Run multiple units on a single PC
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. Your PT-104 however, is inherently accurate due to its innovative 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). A high-performance 24-bit ADC is used to achieve the 0.001 °C resolution.
Temperature
Your PT-104 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 accurate measurements). A wide range of PT100 sensors (see Accessories) are available for use with your PT-104.
Resistance
When measuring resistance, your PT-104 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
Your PT100 data logger is supplied with PicoLog data logging software. 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.
But I need to measure more channels…
Your PT-104 is capable of measuring up to 4 channels at once. Need more channels? No problem. Using PicoLog you can connect up to 4 Pico data loggers to one PC — giving you a potential 16-channel PT100 data logger, or the ability to use your PT-104 logger with other Pico devices such as the PicoLog 1000 multi-channel data logger.
The ultimate in portability
With both USB and Ethernet interfaces your PT-104 can be used in a variety of situations. If you need a portable solution that can be used at various locations and is fast to set up and use, simply connect your laptop to the PT-104 by USB. Need to monitor a situation over a period of hours or days, or from a remote location? Plug your PT-104 into a spare port on your network and then access it remotely either from your LAN or over the internet (using Power over Ethernet (PoE) technology means that you don’t even need a separate power supply).
When accuracy is paramount the PT-104 is what you need
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. Having both USB and Ethernet interfaces gives you the choice of how you connect and power your PT-104, along with the ability to access the PT-104 remotely over a LAN or the internet. When the accuracy of your temperature measurements is paramount the PT-104 is what you need.
