1 ECAPm level transmitter is a capacitive level sensor for level measurement of conductive liquid, nonconductive 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 level measurement are offered especially for machinery manufacturers. Application Areas iquid 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. ticky hot and high viscosity liquid, acid and chemical liquids. ECAPm CAPACITIVE EVE TRANMITTER ECAPm 101 ECAPm 203 ECAPm 305 ECAPm 408B, 408T, 408Tm 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.

2 Working Principle : Capacitance definition, assuming two parallel conductive plates are used; C= e o. e r. d Ýzolasyon C: Capacity, Farad : urface Area, m2 d: Distance, m d C R Metal Tank However, there are scarcely any sensor type which this definition can be pratically utilized. Above Formula can no longer bi reliable especially when residual areas increase due to large distance (d) (which is usually the case). Thus, measuring impedance for distance measurements give more accurate results than capacitance measurement. Capacity Impedance Excitation applied between 10KHz 250KHz based on length for all our models. ( =2xpxf) inearity error that may be caused by conductivity component (R) effect is prevented by electronic circuit design and mechanical design. Reduced to a level lower than e 1ppm, acceptable as zero.

If adjustment is needed again, 4mA output adjustment can be performed by Z trimmer after the tank is filled until initial level. Measurement field (span) adjustment: 20mA is adjusted at factory exit, assuming tank is filled up to length of electrode. If adjustment is needed again, 20mA output adjustment can be performed by trimmer after filling the tank up to a desired level. 4 ECAP
