Capacitance Switches and Transmitters

Capacitance Switches and Transmitters

Capacitance level instruments have a capacitive level sensor for level measurement of conductive liquid, low conductive liquid, granulated materials with solid particles, adhesive and acid/basic liquids. When a material comes between electrode rod and tank wall, a capacitance change occurs and when this change exceed adjustment threshold, contact output is delivered. Full-empty calibration can be performed easily and safely. Different designs and different solution related to industrial levelmeasurement are offered especially for machinery manufacturers.
 
Application Areas
Liquid tanks, food machines, cooling liquid tanks, shipping, glycol tanks, brine, waste water tanks. Oil tanks, CO2 liquid tanks, high temperature tanks, non-conductive liquids. Grain stores, cement, sand feed, flour, milk powder, organic and plastic granule. Sticky hot and high viscosity liquid, acid and chemical liquids.
 

Advantages
There are no moving parts. High pressure and temperature resistant design.
Modular structure with easy assembly. Not affected by foam, liquid splashes.
Not affected by vibration, has robust mechanical structure.
Zero span adjustment is easy.Measurement along whole sensor.
Operability with reverse assembly.

Conductivity Switches and Transmitters

Conductivity Switches

Conductivity level switches are used for checking liquid level of tanks and boilers. As it does not have any movable part, it can be used in the critical ambient and in the liquids with solid particle,
low density and high viscosity.

When liquid leved comes to the level of isolated electrode, current passage starts or stops between electrode andliquid. Strengthened this AC current may be assesed with a relay cirruit.

Application Areas
lt is an economic and safe solution for air pressure tank applications, water level control of steam boilers and conductive tanks.

Advantages
Economical
Easy to install
No moving parts
