Two Wire Capacitance Level Transmitter

Owing to a modernized infrastructure for trouble-free processing and post-production, we are instrumental in offering Two Wire Capacitance Continuous Level Transmitter. Other Details: Free flowing homogeneous liquids, like oil, raw water, WFI, DM/DI water etc. Suitable for top mounting. Process temperature max. 200 °C. Process pressure max. 20 bar. Suitable for corrosive liquids. Working Principle:- The probe forms a capacitance with the metallic tank-wall. The capacitance is sum of three capacitance C(air)=e(air) x P x (H - L) C(material)=£(material) x P x L C(residual) is due to device itself. Where e(air) is the dielectric constant of air=1. E(material) is dielectric constant of material. P is constant of probe and installation, H is the active length of probe and L is the level of material. Capacitance to level translation is performed with the aid of on-site calibration also called "wet-calibration" The device stores a low level capacitance as level for 4mA and high level capacitance as level for 20mA as defined by the user.
