Level Sensors and 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

Vibration Fork Level Switches ... New!

ProSense VFL Series liquid level switches are offered in two process connection sizes with short and extended insertion lengths, standard and high temperature constructions, and a 3-wire DC switch output for connection to controller inputs or a 2-wire AC/DC switch for control of valves and pumps.

• 1/2" or 3/4" male NPT process connection
• Short (1.89") or Extended (3.44") insertion lengths
• Standard or high process temperature ranges: -40 to 212°F or -40 to 302°F
• Ideal for applications not suitable for other liquid point level technologies due to conductivity, turbulence, buildup, air bubbles, foam, pressure, temperature, and viscosity changes

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.
