4051SLT Level Transmitter
SKU: 4051SLT
Newer 4051S-platform pressure-based level transmitter — same direct-mount / remote-mount / balanced / Tuned-System level capabilities as the 3051SAL but on the modernized 4051S electronics platform. Industry-leading 20-year warranty and 20-year stability. Built-in Bluetooth for safer-from-distance configuration without entering the hazardous area. Built-in advanced diagnostics. The right choice for new builds (vs the established 3051SAL for retrofits matching existing 3051S installed base).

3051S Submersible Level Transmitter
Cable-deployed wireless submersible level transmitter — slim 0.75-in (20 mm) diameter piezoresistive sensor lowers down a marked cable to the tank/sump bottom and reports hydrostatic head pressure (level) wirelessly via the WirelessHART radio in the surface-mounted 3051S transmitter. SmartPower battery delivers up to 10-year maintenance-free operation; battery replacement does NOT require removing the transmitter from service. Optional LCD on the surface unit shows level + sensor temperature. Best for sumps, water wells, lift stations, condensate collection tanks, and any retrofit application where running conduit to a tank-bottom port is impractical.

3051SAL Hydrostatic Level Transmitter
Premium hydrostatic level transmitter — leverages the 3051S Scalable pressure-platform with Tuned-System diaphragm-seal capability for both pressurized and vented tank level measurement. Wide pressure envelope (up to 10,000 psi / 689 bar) and process temperature range (-157°F to 770°F / -105°C to 410°C) depending on fill fluid. Supports direct-mount, remote-mount, balanced systems, and Tuned-System assemblies. SIL 2/3 certified. 4-20 mA HART, WirelessHART, or FOUNDATION Fieldbus output. Best for tall tanks with extreme process temperatures, hot/aggressive media, or tank-bottom installations where the 1199 / 1299 diaphragm seals isolate the transmitter electronics from the process.
