There are three major types of temperature probe: thermocouples; thermistors; and RTDs (resistance temperature devices). Each type needs its own preamplifier which then provides a signal to the e-corder. However, for many applications, the size and shape of probe is usually more important than the probe type.
For use with e-corder eDAQ offers:
or for direct connetion to a computer with Pod-Vu software:
- EPU356 Thermocouple isoPod with USB
Other brands of temperature meter that provide an analog voltage signal will also be compatible with e-corder.
Available probes from eDAQ include:
- ET405 K-type temperature probe
- ET1400 T-type thermocouple probe
- ET020 Thermistor Temperature Probe
- ET021 RTD Temperature Probe
In general, the smaller the probe the faster the response time. For high speed response times very fine thermocouples are usually employed. A wide variety of T-type thermocouple probes are available from Physitemp which can all be used with the Thermocouple isoPods
