LTH Level Transmitter – Hydrostatic
Piezo-resistive hydrostatic level transmitter — submersible or side-mounted, 0.5% accuracy, range up to 200 m WC.
LTH is based on Piezo Resistive Technology — it senses the pressure of liquid at the bottom of the tank and provides a linear 4–20 mA output. Pressure is directly proportional to the height of liquid with known density. Available as Submersible type (top mounted, probe submerged, vent-tube cable) and Non-Submersible type (side mounted to tank). Highly accurate, compact and corrosion resistant.
Key Features
- Cost effective with no moving parts
- Easy to install and handle — simply submerge or side-mount
- High precision & stability — 0.5% full scale accuracy
- Compact, rugged and corrosion-resistant SS316 probe
- Submersible type with vent-tube PVC cable
- Non-submersible type for side-mounted process connection
- Probe IP68 rated for full submersion
- Range 0.5 to 200 metres WC
