Tip-sensitive RTDs

CUT-TO-LENGTH

Overview

The probe sensing tip is constructed of copper alloy which istwenty times more conductive than stainless steel. The sensors react more quickly to changes and indicate tip temperature instead of stem temperature which increases accuracy. Minco recommends 0.250" diameter probes for use in thermowells. Element Model for probe diameter: 0.188"(4.8 mm) 0.215" (5.5 mm) 0.250" (6.4 mm) Single element RTDs: No armor over leads Platinum (0.00392 TCR) 100

Platinum (0.00385 TCR) 100 Ω ±0.1% at 0°C(Meets EN60751, Class B) S854PD S851PD S853PD Leads: 2, 3, or 4 leadwires, stranded copper with PTFE insula-tion. AWG 22, except 0.188" diameter dual probes AWG 24. For 2-lead RTDs add 0.03 Ω per foot (0.05 Ω per foot for 0.188"diameter dual probes) of combined case and lead length to element tolerance. Copper (CA, CC) models must have 3 leads. Platinum (0.00385 TCR)100 Ω ±0.5% at 0°C S884PE S881PE S883PE Time constant: 2.0 seconds typical in moving water. 3.0 sec-onds for dual element models.
