Brief description
The sensor detects the electrolytic conductivity of a process liquid. It uses the inductive principle of
measurement. Because it uses the inductive method of measurement rather than the conductive
2-pin or 4-pin measurement method, the sensor is virtually maintenance-free. The measuring accu-
racy is practically unaffected by accumulations and grease or oil film on the surface of the sensor.
A (Pt1000) temperature sensor acquires the process temperature at the same time. The temperature
sensor can either be exposed in a stainless steel pocket (ultra-fast response) or be located right in-
side the plastic body (with PVDF, only the internal option is possible). Internal installation is advisable
if the sample media could chemically attack the stainless steel pocket.
The standard sensor body material is polypropylene (PP). PVDF is also available as an alternative.
A vast number of process connections are available to ensure system flexibility, even to provide
spare equipment for older devices.
The JUMO ecoLine Ci sensor is designed for connection to the following transmitters: JUMO
AQUIS 500 Ci (as per data sheet 202566), JUMO AQUIS touch S/P (as per data sheet 202580/
202581), and JUMO digiLine Ci ST10 (as per data sheet 202760).
Typical areas of application:
The sensor is primarily designed for use in water engineering systems. Typical areas of application
include general water engineering (drinking water and wastewater), air-conditioning and cooling
plants, dilution monitoring in cooling towers, flushing tanks, carwashes, sea water desalination (inlet),
monitoring swimming pool water, etc. There is an immersion variant that can be used in open chan-
nels and containers.
Product advantages:
• Practically maintenance-free conductivity measurement
• Materials are FDA/food-use approved
• A variety of process connection variants
• A fast-response temperature sensor
• A compact, proven sensor
