Nohken Model KRV

Capacitance level sensors KRV

Features
  • No adjustment required
  • High sensitivity with dielectric constant as low as 1.1
  • Ignores coatings and build up
  • Detects solids, liquids, and interface of two immiscible liquids

The KRV series of capacitance sensors are designed for point level detection of liquids, solids, powder, or interface between two immiscible liquids. Radio Frequency sensors are typically used to detect liquids, but have a difficult time with solid or powder mats rials. The KRV series overcome this limitation by having a parallel LC circuit on its oscillator and five switch selected sensitivity ranges. The KRV series easily detect solid and powder materials such as plastic powder/pellet, fly ash, carbon black, and similar substances. The KRV series reliably detect the interface between two immiscible liquids, oil and water as an example. The KRV can be set to operate in water but not in oil. Additionally, the KRV will ignore heavy oily build up on its electrode.

Nohken Model KSV

Model KSV - For Conductive Medium

Features
  • Ignores heavy conductive build up
  • Single probe/Mechanically strong

The KSV series of capacitance sensors are made specifically for point level detection of conductive medium. Applications include water; chemical solutions, acid based slurries, conductive granules, and sticky liquids.

Build up is one of the most common problems for capacitance sensors. Conventional Radio Frequency sensors solve this problem by using a guard probes (the second or third element to the electrode). But this complicated probe construction tends to make probes easily broken, particularly if twisted in agitated containers. Consequently, conventional RF sensors are installed vertically and limited to a fixed length, foamed in one piece.

The KSV series have overcome 1his limitation by using 1he series resonance circuit and a single electrode. This circuit corrects for conductive build up by measuring its resistance. The single electrode can be mounted in virtually any position and is available with a number of standard mountings.
