Your application dictates the size of the PRT Probe to be used. Generally the smaller the diameter the faster the thermal response time and the shorter the necessary immersion length for accurate instrumentation, but with less strength than a probe with a larger diameter. Use the sheath size that will withstand the rigors of your application but with minimal effect on it. Because the element can be broken if the sheath is bent in the elemnet area it is recommended that a minimum of 0.187" diameter thermometer be used. Small diameters are available on request. (Please consult the factory).
