We offer pressure based level measurement solutions which use pressure sensors known for their high precision and workability with a wide range of pressure. With its partnership with Keller, Sapcon features pressure based level transmitters for water and waste-water industries. KELLER AG für Druckmesstechnik is a leading manufacturer of isolated pressure transducers and transmitters with its headquarters based in Winterthur (Switzerland).
Principle
Hydrostatic pressure is proportional to the height of a column of fluid. The pressure generated depends on the density of the fluid and the gravitational pull acting on it. Level probes measure this pressure, with the ambient pressure also factored into their
measurement method or design. Pressure measurements require high long-term stability in order to meet the standard required of a static measurement.
Features and Unique Characteristics of Pressure Based Level Transmitters
Two kinds of pressure transmitters for level measurement are offered: Piezo resistive transmitters and Capacitive Transmitter for low pressure range. Their respective models with technical specifications are stated below.
1. PIEZO RESISTIVE TRANSMITTERS (RANGES FROM 2 TO 300 mH20)
2. CAPACITIVE TRANSMITTER FOR LOW PRESSURE RANGE
