When a highly precise ceramic pressure sensors with long-term stability for reliable and safe water measurement is required, the rope probe from Endress+Hauser is the solution.
The FMX 167 Waterpilot is an economical hydrostatic pressure sensor with an external diameter of 22mm. The dry measuring cell with its robust ceramic diaphragm is extremely resistant to mechanical influences like abrasion.
A temperature sensor has been provided as an option and allows simultaneous measurement of the level and the temperature of the medium. The protection of the probe against climatic influences is ensured by potted electronics, a durable conical seal of the of the load-bearing cable and climatic protection in the pressure compensation. Integrated overvoltage protection prevents damage, e.g. by voltage peaks.
The FMX 167 level probe has been certified for applications in hazardous areas (EEx ia). The complete measuring device consists of the FMX 167 Waterpilot with 4…20 mA output signal, a 10…30VDC power supply as well as possible transmitters like contactors, display or registration units.
