Level Flowmeter, PH Sensor, Endress Hauser Pressure Transmitter

Pressure transmitters can measure the pressure of gases, liquids and steam, converting the pressure magnitude into standard electrical signals and transmitting them to industrial measuring instruments such as PLCs, meters and control cabinets.

Three common types
Gauge pressure transmitter

Most commonly used, it measures the pressure of pipelines or equipment relative to atmospheric pressure.

Absolute pressure transmitter

It measures pressure relative to a vacuum and is used in negative pressure, vacuum equipment, and precise working conditions.

Differential pressure transmitter

It measures the pressure difference between two points and is used to calculate liquid level, flow rate, and pressure difference.

Key Points for Type Selection
TypeDefinitionTypical Applications
Gauge PressureZero reference is atmospheric pressure, can be positive or negativeWater pipe pressure, container pressure (most common)
Absolute PressureZero reference is absolute vacuum, only positive valuesVacuum pumps, atmospheric pressure monitoring
Differential PressurePressure difference between two pointsFlow measurement (orifice plate), liquid level measurement
Evaluate the medium and working conditions
  • Temperature: Ensure that the medium temperature is within the operating temperature range of the transmitter. For high-temperature media (200-400℃), high-temperature types or the installation of condensate tubes is recommended.
  • Corrosiveness: Select the wetted material based on the medium composition (such as 316L stainless steel, Hastelloy, ceramic diaphragm, etc.).
  • Cleanliness: For viscous or particulate-containing media, it is recommended to use a flat diaphragm design to prevent clogging.
