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

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
