Data logger
ESS3 S4
Data logger station with four sensors
The ESS3 S4 series devices are used to record pressure and temperature in gas pressure regulating and metering stations.
They are also suitable for measuring points without a power supply where up to four measured values must be recorded over the long term.
Measurement parameters
- Relative pressure
- Absolute pressure
- Differential pressure
- Barometric pressure
- Temperature
- Alarm contacts (SAV, door, …)
-
Extremely robust for field use
(Ex-approval + IP68)
-
Autonomous long-term operation
(battery + memory)
- Easy connection to MODEM2024
Typical applications
The ESS3 S4 is particularly suitable for:
Monitoring in gas pressure regulating and measuring systems
Monitoring in water pumping stations
Stationary monitoring tasks
Features
Up to four freely configurable sensors for pressure and temperature
Up to six inputs for alarm contacts (e.g., SAV, odor, door contacts, …)
Large data memory, efficiently utilized through data compression, allows data to be stored for several years
Long battery life for multi-year operation without battery replacement
Easy operation via device buttons/display
Optical data interface to the PC
Powerful PC analysis software
Explosion protection, Zone 1
