Electronic Submersible Level Transmitter
Model LT10M
Electronic submersible level transmitter (LT10M) with a CVD sensing element and all-welded stainless steel back end, 0.25% FS typical accuracy, ranges from vacuum to 400 bar, IP68 immersible versions to 200 m H2O, and 4–20 mA, voltage or millivolt output.
Overview
About the Electronic Submersible Level Transmitter LT10M.
The LT10M electronic submersible level transmitter measures liquid level hydrostatically, converting the pressure of the liquid column above the sensor into an electrical signal. It uses a proven CVD (chemical vapour deposition) sensing element, an ASIC for amplified units and modular packaging, with an all-welded stainless steel back end for demanding submersible, industrial and marine applications. Gauge, absolute, vacuum and compound pressure models are available, in submersible, general-purpose and wash-down enclosures, with millivolt, voltage or 4–20 mA current output.
Features
- High stability from the CVD sensing element: long-term drift 0.2% FS per year (non-cumulative)
- Accuracy 0.25% FS typical, optional 0.15% FS
- Ranges from vacuum to 400 bar, in gauge, absolute, vacuum and compound versions
- Immersible versions rated IP68 to a maximum depth of 200 m H2O
- 17-4 PH stainless steel wetted parts; 316 or 17-4 PH stainless steel enclosure
- Fast 0.5 ms response time and a fatigue life of more than 100 million FS cycles
- Resistant to 70 g vibration, 100 g acceleration and 20 g shock
- Meets CE marking requirements for EMC (EN50081-2 emissions, EN50082-2 susceptibility)
- Intrinsically safe versions available with amplified outputs
Options
- Output: 4–20 mA two-wire, 0–5 V, 0–10 V, 1–5 V, 1–6 V, 1–11 V, 0.5–5.5 V, 0.1–5.1 V, 0.2–10.2 V or millivolt
- Nose: sink weight nose cone or plastic nose cone for submersible use
- Pressure ports in NPT, SAE and European (G, R) threads for non-submersible versions
- Electrical connection by cable, DIN plug, bayonet connector or conduit
Applications
- Submersible liquid level measurement in tanks and vessels
- Marine applications
- Industrial pressure and level measurement
- Wash-down areas (wash-down enclosure)
