Level Sensors & Controllers

Level sensors monitor the level of liquids, pellets, powders, and other similar products in tanks and process systems. Available Prosense and other series include contact, non-contact and submersible sensors, as well as float level and proximity switches. Flowline series controllers add the ability to control alarms, pumps, valves and other industrial equipment.

Liquid Level Sensors and Controllers


[Learn More] Flowline Ultrasonic Level Sensors (Non-Contact)	Flowline Ultrasonic Level Sensors (Non-Contact) The Flowline EchoPod®, EchoSonic® II, Echotouch™, EchoSpan® and EchoSwitch® are innovative ultrasonic liquid level sensor families that replace float, conductance and pressure sensors that fail due to contact with dirty, sticky and scaling liquids in small, medium and large capacity tanks. These liquid level sensors can be used in either open or enclosed tanks (not suitable for pressurized tanks). PC software configured or pushbutton configured models are available. Software configured ultrasonic liquid level transmitters start at *$286.00* Software Configured Ultrasonic Level Sensors Overview Pushbutton configured ultrasonic level sensors/transmitters start at *$662.00* Pushbutton Configured Ultrasonic Level Sensors/Transmitters Overview

[Learn More] Flowline Level Sensors (Contact)	Flowline Level Sensors (Contact) Ultrasonic Level Switches: are intrinsically safe and provide reliable liquid level detection of chemical, solvent, hydrocarbon and petroleum based liquids. Vibration Point Level Switch: provides reliable liquid level detection of dirty liquids such as those with light to medium coating, scaling or foaming characteristics. Capacitance Level Switch: provides reliable high or low liquid level detection of water based conductive liquids with light coating, crystalizing or scaling characteristics with a 1A relay output. Buoyancy Level Switch: provides reliable liquid level detection of relatively clean water and chemical solutions. Flowline level sensors (contact) start at *$114.00* Flowline Level Sensors (Contact) Overview

[Learn More] Flowline Level Controllers	Flowline Level Controllers Switch-Pro™ general purpose level controllers are available in three discrete sensor input configurations for alarms, pump and valve control. The LC52 DataPoint™ general purpose controller for analog sensor inputs provides single tank level indication with 2 relays, up to three setpoints and an isolated analog repeater. Switch-Pro LC40 Remote Level Controller: one level sensor input and one non-latching 10A relay output for high level or low level alarm Switch-Pro LC41 Remote Level Controller: two level sensor inputs and one latching 10A relay output for automatic fill or empty control Switch-Pro LC42 Remote Level Controller: three level sensor inputs and one latching 10A relay output and one nonlatching 10A relay output DataPoint LC52 Remote Level Controller: one 4-20 mA input, two relay outputs, One 4-20 mA output Flowline level controllers start at *$200.00* Flowline Level Controllers Overview

[Learn More] ProSense Float Level Switches	Float Level Switches ProSense float level switches provide a low-cost general purpose solution for single point monitoring of liquid level in a variety of applications. Designed for shock and vibration resistance, ProSense float level switches ensure long and trouble-free service. Powerful permanent magnets within the float actuate a highly reliable and repeatable hermetically sealed reed switch as the float rises and lowers with liquid level.- general purpose, low-cost! These switches are available in several different material constructions for compatibility with many types of liquids, a wide temperature range, and various system pressure requirements. Vertical and horizontal mounting styles with several mounting thread variations are available for ease of installation. Vertical Top-Mount Vertical Suspendible / Submersible Horizontal Side-Mount Float Level Switch Kits Float Level Tilt Switches ProSense float level switches start at *$11.00* Float Level Switches Overview

[Learn More] ProSense Submersible Level Sensors	Submersible Level Sensors The ProSense SLT series submersible level sensors provide continuous liquid level measurement by sensing the hydrostatic pressure produced by the height of liquid above the sensor and providing a 4-20 mA output signal compatible with PLCs, panel meters, data loggers, and other electronic equipment. SLT1 Series Transmitter with 1-inch Diameter Housing SLT2 Series Transmitter with 2.75-inch Diameter Diaphragm and Protective Cage Submersible Level Transmitter Vent Filter Submersible Level Transmitter Bellows Junction Boxes for Submersible Level Transmitters Submersible Level Transmitter Replacement Nose Caps SLT series submersible level sensors start at *$306.00* Submersible Level Sensors Overview

[Learn More] Proximity Level Sensors	Proximity Level Sensors Capacitive: AutomationDirect offers a variety of capacitive level sensors. NPN and PNP logic outputs and normally open or normally closed output models are available. All capacitive proximity sensors have LED status indicators to verify operation at the switch; and all capacitive proximity sensors are IP65 or IP67 rated. Ultrasonic: SU, UK, UT and TU series round body reflective ultrasonic distance sensors emit a sound impulse and measure the elapsed time of the returned echo signal reflected off of a detected object. Capacitive and ultrasonic proximity sensors. 12mm Round Capacitive Proximity Sensors (CM1 Series) 18mm Round Capacitive Proximity Sensors (CK1 Series) 30mm Round Capacitive Proximity Sensors (CT1 / CTV Series) Rectangular Capacitive Proximity Sensors (CR1 Series) Ultrasonic 18mm Proximity Sensors (UK / SU Series) Ultrasonic 30mm Proximity Sensors (UT / TU Series) Proximity level sensors start at *$60.00* Proximity Level Sensors Overview
