Data logger

ESS3 A1

Data logger with an axial sensor

The ESS3 A1 series devices measure pressure in water networks and are suitable for short-term measurements for fault localization as well as for long-term monitoring.

Other applications include the validation of pipe network calculations and the documentation of leakage tests according to DVGW W400-2.

Measurement parameters

Typical applications

The ESS3 A1 is particularly suitable for:

Fault analysis in the gas network

Long-term monitoring in water networks

Pipeline network calculation

Leak testing G469 / W400-2

Sensor

The sensor is the metrological link to the application.

Performance and user-friendliness are therefore paramount:

Sensor replacement by the user is possible and immediately ready for operation without recalibration

Stainless steel encapsulated, piezoresistive sensor with high long-term stability, resistant to aggressive media

High resolution of measured values; multiple measuring ranges possible for a single sensor

Measurement of media temperature

High measuring rates due to high natural resonant frequency, making it ideal for measuring pressure surges

High overpressure safety and high burst pressure

Sensibly graded fixed and user-definable measuring ranges and various accuracy classes up to ± 0.05% of the F.S. (Full Scale)
