Hengesbach Capacitive Level Probe Type Leveltec S-L-LR



The level probes of type LEVELTEC are suitable for liquid media. Due to the capacitive measuring process, the LEVELTEC devices can reliably detect a wide range of conductive and non-conductive media. The dielectric constant (DC value) of the medium can easily be stored if the teach-in-key „HIGH“ in the level probe is briefly pressed. The LEVELTEC is factory-set to a DC value of ε=25. An even more exact detection of the switching status takes place if
the Teach-In key “LOW” is pressed during the final assembly status without product medium. This has an advantage especially with low DK values. The devices are designed for product media temperatures of 100°C continuous and 140°C. As an output signal, the level probes of type LE



VELTEC are equipped with an active switch output with a maximum output current of 50mA. This can be connected directly to a PLC.

The LEVELTEC level probes are equipped with a G1/2” screw-in thread with elastomer-free sealing cone as a process connection. To enable adaption to the process, weld-in sockets and various adapters, e.g. for VARIVENT®, DIN11851 conical couplings.  The probe tip, the only component in contact with the medium, is manufactured from FDA-compliant PEEK. The housing and the extension tube of the process connection are made of 1.4301 (304). The LEVELTEC L capacitive level probe is used specifically for low level (empty) detection at tank bottoms for pasty and adhesive media. The LEVELTEC LR capacitive level probe is used specifically for pump protection for pasty and adhesive media in pipes. Due to its construction of an inactive extension of the measuring pipe, the LEVELTEC L is insensitive to product deposits, thereby guaranteeing reliable detection. Due to the temperature resistance of the device, sterilisation and CIP cleaning can be performed.

Features:

LEVELTEC S – Level Detection

  • For level detection of liquid media, regardless of conductivity
  • Foam and Condensate are not detected
  • Simple parametrisation with tech-in key
  • Applicable also for pump protection
  • Vibration resistant, universally applicable

LEVELTEC L – Minimum Detection / LEVELTEC LR – Pump protection

  • Especially for limit detection with pasty media and strong adhesive product
  • Product monitoring in pipes/pump/dry running protection
  • Insensitive to foam
  • Especially for installation in piping
  • Teach-in key
