Palmer Wahl DST620&660_Probes | Digi-Stem DST620 & DST660 Dual RTD Probes | 2 x Pt100 Class A
DST620&660_Probes are built-to-order dual-sensor RTD probes for Digi-Stem DST620 and DST660 series meters, which are sold separately. Each probe carries two Pt100 Class A 4-wire sensors in MgO packed MI cable: the primary feeds the battery-powered indicator, while the independent secondary is powered by customer-supplied 24 V DC loop power and is accessed through a 1/2 in NPT female port on the side of the housing.
Key features
- Probe ID on rigid probes and on remote probes with cable of 25 m or less; can be disabled on request
- Ten-conductor remote cable up to 200 m
- Quick disconnects let the meter and probe go to the lab while the cable stays installed
- Adjustable angle, rigid or remote mounting
- 3-A Sanitary Standard 74-06 fittings in welded 316L
- Spring loaded option with about 1 in travel
A NIST traceable certificate of conformance is available.
