Specific models are not listed on the site. Each category page sets out the selection parameters to specify — or ask an engineer to help specify the instrument.
Before you specify
Nine questions decide the instrument.
These are the facts an engineer needs to recommend a measuring principle and a device. Send what you know — gaps are part of the technical conversation, not a reason to wait.
- 01Measurement parameterWhat has to be measured, analyzed or controlled.Pressure · flow · level · temperature · humidity · gas · liquid quality
- 02MediumWhat is in the pipe, vessel or duct.Liquid · gas · steam · slurry · process-specific
- 03Process rangeMinimum, normal and maximum — with the unit.e.g. 0–16 bar g, 20–120 m³/h
- 04Process conditionsWhat the instrument has to survive.Temperature · pressure · corrosiveness · viscosity · vibration
- 05InstallationWhere and how it mounts.Inline · insertion · tank · duct · panel · skid · remote
- 06Area classificationWhether the location is hazardous.General · hazardous zone · unknown
- 07Output / communicationWhat the receiving system accepts.4–20 mA · HART · Modbus · Ethernet · relay
- 08Control-system environmentWhat it connects to.PLC · SCADA · DCS · standalone · unknown
- 09Documentation needWhat you need back.Datasheet · specification · selection help · quotation
