Pointek CLS500

Pointek CLS500 is a 2-wire capacitance point level switch for detecting interfaces, solids, 
liquids, slurries and viscous materials in critical conditions of extreme temperature and 
extreme pressure. It uses a unique frequency-based measurement system and patented 
Active-Shield technology to deliver highly accurate, repeatable results. The measurement is 
unaffected by moisture, vapors, foam, temperature and pressure variations, or material build-
up around the mounting glands.

Pointek CLS500 combines a sophisticated, easy-to-adjust transmitter with a measurement 
electrode and process seal designed to accommodate numerous configurations. The 
advanced electronics and integrated local display provide for one-point calibration without 
interrupting the process, and the probe shield design eliminates the need for frequent 
recalibration.

Pointek CLS500 can be used as a pump controller, by connecting the 2-state mA output 
and/or the solid state switch to a relay, and activating a pump via an auxiliary power 
circuit.

Pointek CLS500 is equipped with: 

• Smart Transmitter with patented Active Shield technology and variable 

frequency oscillator

• Remote adjustable commissioning / control capabilities via HART

1

• Analog (2-wire) 4 to 20 mA or 20 to 4 mA output
• 2-state functionality (4 or 20 mA / 20 or 4 mA)
• Solid state switch
• Adjustable hystereses on/off for solid-state output and for current signal
• Damping functionality
• Signal current (measurement/detection) according to NAMUR NE 43
• Integrated local display for commissioning and services activities
• Full range of local/remote diagnostic facilities
• Polarity-insensitive current loop
