The LH840 – Ceramic Hydrostatic Level Transmitter comes with a thick film capacitive ceramic diaphragm. The benefit of using a ceramic diaphragm is that it is resistant to build-up of dirt or debris and is extremely resistant to various chemicals. It is also commonly indicated when suspended solids within the medium are a concern.
The LH840-Ceramic is mounted within a 316SS (or PVC used for mediums corrosive to 316SS) cylindrical body houses the electronic module along with the thick film flush mounted ceramic sensing element. The unit comes with a pre-ordered fixed length of vented polypropylene cable and does not have an enclosed housing or process connection.
All of Sitron’s Hydrostatic Level Probes have a 4-20mA (2-wire) output signal, are fully temperature compensated within the stated range and are offered with surge protection. HART communication protocol is also available. Pressure ranges from 0 to 580 PSI (0 to 40 bar) gauge.
