Using third party PT100 probes with Tinytag loggers
Information about how to connect third party PT100 probes to our loggers.
We supply a range of PT100 probes for use with our loggers, but you can use your own probes if required.
The ACS-9703 datasheet (see Connection Information 2) provides wiring instructions for 2, 3 and 4-wire PT100 sensors.
We recommend the use of 3-wire, class A sensors.
2-wire and 4-wire sensors can be used, but the accuracy is reduced when 2-wire sensors are used and loggers will not read the fourth wire of 4-wire sensors.
The ACS-9703 5-pin Tajimi plug should be used with the following products:
Tinytag Plus 2: TGP-4104
Tinytag View 2: TV-4104
Tinytag Ultra Radio: TR-3101
