AutomationDirect: Klemsan Liquid Level Controller and AchieVe Wall-Mount Humidity Sensor
September 8, 2026
The Klemsan liquid level controller provides automated control for tank fill, drain, and water transfer applications using conductive probes with no moving parts.
Five selectable operating modes support 2- and 3-probe level control as well as 6-probe transfer systems. During transfer operation, dual source and destination tank monitoring stops the pump when the destination reaches full capacity or when the source drops too low, helping prevent overflow and dry-run conditions.
The AchieVe HUM-W-RS485 wall-mount sensor combines temperature, relative humidity, and dew point measurement in a single compact device for industrial, commercial, and building automation applications.
Wide sensing ranges accommodate many environmental conditions, while Modbus RTU (RS-485) communication with configurable byte order streamlines integration with a variety of control platforms. Built-in data logging registers track running minimum, maximum, and average values, and an IP67-rated enclosure protects against dust and water ingress in demanding environments.
The Klemsan level controller is priced at $75.00 (K2LC-D2-115-230), and the AchieVe humidity sensor is priced at $95.00 (HUM-W-RS485).
