Foxboro RTT20-D1LDQFD-D2 Temperature Transmitter

Foxboro RTT20-D1LDQFD-D2 Temperature Transmitter is a 12–42 VDC powered instrument whose model designation identifies it as a dedicated temperature measurement transmitter within Foxboro’s process instrumentation lineup, and the RTT20-D1LDQFD-D2 designation marks the exact model within Foxboro's broader product family. It specifies a temperature measurement range of 0–1562°F, enabling precise monitoring of high-temperature processes and providing a standardized signal path for integration with compatible control systems; its range covers a wide span of industrial needs and supports flexible power supply options in different facility configurations. The unit's 3.5-inch form factor is designed for compact installations, allowing placement in limited-space panels, instrument enclosures, or nearby field junctions where reliable temperature data is required, and it supports straightforward mounting alongside other Foxboro instrumentation in typical control rooms. This model is identified by RTT20-D1LDQFD-D2 and, as a Foxboro transmitter, aligns with the broader product family, providing a clearly defined specification set—12–42 VDC input, 0–1562°F range, and a 3.5-inch footprint—that supports accurate selection for replacement or new installations in industrial environments.
