Palmer Wahl DST600&640_Probes | Digi-Stem DST600 and DST640 RTD Probes | Pt100 Class A
The DST600&640_Probes are single-sensor RTD probes built to specification for Digi-Stem DST600 and DST640 retort thermometers, sold separately from the meter. Each uses one Pt100 Class A 4-wire RTD in MgO packed MI cable. Because there is no secondary sensor, remote versions use a six-conductor cable rather than the ten-conductor cable of the dual-sensor families, with IP67 quick disconnects available at either end.
Key features
- Adjustable angle, rigid (bottom connected) or remote mounting
- NPT, swivel nut, unthreaded transition or 3-A sanitary fittings
