316 SS Single Point Ultrasonic Liquid Level Switch

The LVSW-701 Series liquid level switch is a direct replacement for mechanical float-type devices. The switch employs proven ultrasonic technology and solid state electronics.

Boiler Water Level Control, Low Cut-Off & Feed-Water, Snap Switch, Flanged

The Series 123 & 125 Boiler Water Level Controls ensure reliable low water cut-off and feed-water management, featuring a transparent cover for easy monitoring.

Paddle Level Switch, 1 RPM Motor, 1-1/4" NPT, for Bulk Materials

Paddle Level Switch is a magnetic drive that is time proven by decades of use. Applications include mining, food and beverage, silos, and hoppers.

Vertical Mount Compact Single Station Level Switch

The LV500-Series are small displacement single station level switches. Very compact, the switches are ideal for restricted or limited space. The overall length is 2.1 inches.

Vertical Float Switch - Durable Polypropylene, Heat & Chemical Resistant

The Vertical Float Switch features durable polypropylene construction, offering heat and chemical resistance for reliable liquid level control in various applications.

Submersible Optical Switch for Level or Leak Detection

The LVF-200A-R Series optic sensor creates a pulsed beam of infrared light which is reflected on the oblique flat sensor tip. If the tip is dry, the light beam is recognized.

Tuning Fork Level Switch for Powders, Immune to Vibrations, No Calibration

The Tuning Fork Level Switch for Powders offers reliable performance without calibration, designed to be immune to vibrations for consistent level detection.

Adjustable Set Point Capacitance Level Switches

The LVCN4300 Series level switches are flexible, as well as cost effective, level solutions for a great variety of applications. Rods can be encased in PTFE tubing as an option.

Non-Intrusive RF Capacitance Sensors Selectable NO or NC

The LVP51 RF capacitance sensors deliver accurate liquid level detection with an SPST mechanical relay output. The sensor mounts directly to the wall of any standard tank.

Vertical Mount 316 SS Liquid Level Switches

Constructed entirely of 316SS, The LV-40 Single Station Level Switch is specifically designed to withstand the effects of a wide range of chemicals.

Capacitive RF Single Point Level Switches

Capacitance switch ideal for low and high level detection for both liquid and solids. It can also detect level without being in contact with the product through a sight glass.
