ESS3 R1
Measuring device with radial pressure sensor
The ESS3 R1 series devices measure pressure, differential pressure, and temperature in gas, water, and district heating networks and are equally suitable for liquid and gaseous media in industrial applications.
The battery-operated, modular devices consist of a control unit (housing, processor, software, display), sensor, and battery.
They are approved for hazardous areas (Zones 1 and 2) and are waterproof up to protection class IP68.
Measurement parameters
- Relative pressure
- Absolute pressure
- Differential pressure
- Barometric pressure
- Temperature
-
Extremely robust for field use
(Ex-approval + IP68)
-
Autonomous long-term operation
(battery + memory)
-
Contactless data readout
(IrDA)
Typical applications
The ESS3 MODEM2024 is particularly suitable for:
Fault analysis in the gas network
Monitoring in gas pressure regulating and measuring systems
Pipeline network calculation
Leak testing G469 / W400-2
Sensor
The sensor is the metrological link to the application. Performance and user-friendliness are therefore the main focus:
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 resonance frequency
High overpressure safety and high burst pressure
Special versions, e.g., for O2 measurement
Sensibly graduated fixed as well as user-definable measuring ranges and various accuracy classes up to +- 0.05% of FSD (full scale deflection)
Temperature sensors suitable as rod probes or for use in thermowells
