Palmer Wahl DST620_660_Meter | Digi-Stem Dual Sensor RTD Thermometer with Transmitter | 4–20 mA
Part Number : DST620_660_Meter
The DST620_660_Meter is the indicator for the Digi-Stem DST620 and DST660 Series, supplied without a probe. Alongside the battery-powered primary RTD, it carries a second 4-wire RTD wired to an internal 4–20 mA transmitter on 24 V DC loop power. Where the DST621 uses a Turck plug, this version brings the transmitter out through an internal terminal block and 1/2 in NPT female conduit connection, suiting hard-wired installations. The series targets critical duties such as low acid canned food processing, with high reliability components selected for FDA 21 CFR Part 113.
