Drop-in replacement controllers for reciprocating air compressors. Replace pressure-switch + timer logic with demand-aware monitoring, intelligent restart, runtime tracking, and predictive-maintenance signals. Single-pump and dual-pump configurations plus replacement temperature sensors.

Pre-wired IP67 controllers for water, irrigation, and sewage pumps. Active fault detection, dry-run and freeze protection, float-switch fault awareness, and operating-hour tracking on top of basic start/stop control. Drop-in for existing pressure-switch installations, or designed in by OEMs building their own pump products.

Solid-state monitoring for CNC machine coolant sumps. TrueLevel CNC replaces float sensors with no-moving-parts digital level and dual-zone temperature sensing, drives an existing tramp-oil skimmer on a computed schedule, and installs in about 30 minutes with no drilling and no machine downtime.

Closed-loop controllers for process equipment. SMEMA-9851 compatible conveyor control that replaces a full PLC in cost and programming complexity, and bolt-on combustion optimization that converts manual-damper wood and pellet boilers to feedback control. Built for installations where a machine that senses its own state beats a fixed setpoint.

Solid-state digital liquid level sensors with no floats, no moving parts, and no open ports. Impervious to clogs, jams, float deflation, and swings in humidity, temperature, and pressure. Dual temperature monitoring, sense lengths from 16.8 to 67.7 inches plus custom lengths to 200 inches, and a life expectancy above 10 years.
