Overview

Nickel (0.00672 TCR)120 â„¦ ±0.5% at 0°C NA These probes have rugged stainless steel cases for use in highpressures or corrosive fluids. Yet their time constants are com- parable to copper-tipped probes at 2 to 4 seconds, compared to 8 to 10 seconds for other all-stainless probes.•All-stainless steel probes for use to 260°C (500°F) •Unique low-mass element reacts quickly to temperaturechanges Specify 0.125" or 0.188" for fastest response, 0.250" or 0.215" forgreater strength and cut-to-length capability (PTFE and SS braid models). S604 Model number:

Case material: S601, S603, S604: 316 stainless steel. S602, S614: 304/305 stainless steel. PD Sensing element from table Case length: 140 Case length: Minimum case length:S602, S604:2.0" (50.8 mm) with PTFE insulated leads;3.0" (76.2 mm) with SS braid over leads.S601, S603:3.0" (76.2 mm).Maximum case length:48" (1220 mm), longer on special order. Specify in 0.1" increments (Ex: 140 = 14.0 inches) X Number of leadwires: Y = 2 leadsZ = 3 leads X = 4 leads (PD only) 36 Lead length in inches Time constant: T Covering over leadwires: Pressure rating: Typical in moving water:S602, S604, S614: 2 seconds. S601: 3 seconds. S603: 4 seconds. 1500 psi (103 bar). T = PTFE onlyS = Stainless steel braid A = Stainless steel armor(S, A not available on S602) Leads: 2, 3, or 4 leadwires, AWG 22, stranded copper with PTFEinsulation, stainless steel braid, or stainless steel armor. For 2-lead RTDs add 0.03 â„¦ per foot of combined case and leadlength to element tolerance (model S602 has AWG 26; add 0.08 â„¦ per foot for 2-lead). S604PD140X36T = Sample part number Insulation resistance: 1000 megohms minimum at 500 VDC,leads to case.
