Capacitance Level Switch for Corrosive Liquids

The Flowline LP15-1405 is a point-level sensor built for corrosive liquid applications. Its polypropylene body and 3/4 inch NPT connection suit vertical mounting in tanks or vessels. The unit provides both an analog and a digital output for integration with control systems. It carries a NEMA 6 enclosure rating for wet environments.

Thermals and Power in Normal Use

The switch operates with media temperatures up to 176 degrees Fahrenheit and withstands pressures up to 150 psi. Accuracy is stated at +/-1 mm for reliable level detection. No external power-draw or noise figures are supplied for the sensor itself. The polypropylene construction resists chemical attack during continuous immersion.

Bundled Accessories and Software Impact

The supplier data lists no bundled accessories, cables, or configuration software for this model. The device functions as a standalone switch using its integral float and NPT threads. Users must provide their own wiring and controller interface to utilise the analog and digital outputs. No mounting hardware beyond the process connection is included.

Questions about this item

How is the LP15-1405 mounted and what alignment step is critical?

Install vertically with a 3/4 in NPT connection; the switch must be perfectly upright because the capacitance probe only calibrates correctly in vertical orientation.

Which component will need replacement first in corrosive liquid service?

The polypropylene body and 1 in float resist chemical attack, so the analog or digital output electronics typically fail before the wetted parts.

What limit appears first during continuous operation at the 150 psi rating?

The 176 °F media temperature ceiling is reached well before the pressure limit, so sustained hot processes trigger the thermal boundary first.
