The PTI-4(USB) is an USB based data acquisition product for thermocouple temperature measurement.

The Contec PTI-4(USB) is an USB based data acquisition product for thermocouple temperature measurement.

The unit is available with four analogue thermocouple inputs and has a 0.01C resolution.

The PTI-4(USB) is compatible with Pt100 (JIS C1604-1997, IEC751:1983) and JPt100 (JIS C1604-1989) sensors.

It measures the temperature range of -200 to 850C when using Pt100 and that of -200 to 510C when using JPt100 sensors.

The unit is compatible with three- and four-wire sensors.

Also, it has an alarm output function (generating an alarm output at a given setting threshold) and disconnection detection function, so it can be applied to an automatic inspection line and a monitoring system.

Onboard programmable output allows for control of relays or external contacts in case of an event or alarm.

The PTI-4(USB) is the perfect measurement tool for customers who wish to do temperature measurement, but do not want the hassle or investment of PLC or Scada systems.

Users simply plug the compact PTI-4(USB) into the computer's USB port - there is no need to switch off the PC or even restart Windows.

The powerful free-of-charge API tool, provided by Contec, allows the user to develop applications in various programming languages, such as Visual C++, Visual Basic etc.

It also provides a hardware diagnostic tool, which keeps the hardware in optimal condition.

Typical applications include monitoring of furnaces, cold storage, computer server rooms and environmental monitoring to name but a few.

Advanced features, such as averaging by count, averaging by time and a digital filter function make it an ideal tool to be used with a notebook personal computer as a test/research tool.
