593: Thermocouple Connection Box

DAQ Catalogue | Data Acquisition Hardware: Ethernet and Internet |  593: Thermocouple Connection Box

593 Thermocouple Connection Box for temperature measurement over USB, Ethernet and Internet

593 Thermocouple Connection Box for temperature measurement over USB, Ethernet and Internet

Price: 135.00 (Excluding VAT at 20%)


A 593 lets a Microlink 751, 752, 751-SG or 851 unit measure thermocouple temperatures. It is an isothermal box with screw terminals with which to permanently wire your signals.

You plug the 593 into the data acquisition unit with a ribbon cable. It includes a cold junction sensing RTD (resistance temperature device) with an associated constant current source (0.8 milliamps). The RTD is used to determine the temperature at the termination point. This reference temperature is used with the analogue input channel's voltage reading to calculate the temperature at the thermocouple's measurement junction.

The cold junction is automatically connected to the auxiliary channel on the data acquisition unit and compensated for in software. The channel is read directly showing the cold junction temperature in Celsius.

The unit also offers protection from high voltages when series resistors are fitted. Noise problems can be solved by fitting an input filter, and broken thermocouple leads can be detected.

For an artice on how to measure temperature see Issue 5 of our Monitor newsletter on the Data Acquisition Intelligence site.
