LTC Level Transmitter – Capacitance Type
No-moving-parts capacitance level transmitter for conductive and non-conductive liquids — with PTFE sleeve for high-temperature service.
LTC is used for sensing the level of a variety of liquids — available for conductive as well as non-conductive liquids. Offered with PTFE sleeve for better insulation & high temperature. In conductive tanks the insulated probe acts as one electrode & the tank wall as another; any change in liquid level changes the dielectric value, changing capacitance proportional to liquid level. Output is industry standard 4–20 mA.
Key Features
- Cost effective with no moving parts — reliable and maintenance-free
- Easy to install with field adjustable switch points
- Works with both conductive and non-conductive liquids
- PTFE sleeve option for aggressive chemicals and high temperatures
- Variety of electrode constructions for wide range of services
- Rigid probes up to 3,000 mm; flexible probes up to 15,000 mm
- 5 mm resolution; 4–20 mA industry standard output
