Pressure sensor - EDS

Gas- or water pressure measurements

EDS-xxxx-MA
  • Precise pressure measurements for monitoring or control applications
  • Several measurement ranges available (2.5, 4 and 6 bar)
  • Maintenance free
  • Ideal for monitoring of aeration- or oxygen pipelines in aquaculture applications

 

Versatile possiblities with pressure measurements.

The SENECT pressure sensor EDS uses a piezoresistive membrane sensor priciple to measure the pressure of gasous or liquid media.

This method is characterized by its long-term stability and therefore suitable for the surveillance of pressure in important pipelines, e.g. the aeration pipeline in fish farms. It is also suitable for liquid media like water. Here, it can for example be used to measure the pressure of the spray (flushing) bar of drum filters.

Beside its use in monitoring and alarming, the pressure measurement can be used to switch or regulate actuators, e.g. compressor-pumps. For all these applications, the SENECT control units offer manifold possibilities to realize optimal controlling mechanisms.

 

Application example for the monitoring of the oxygen pipeline

In this application example, the SENECT|TWO (2 Sensor-input ports, 2 actuator output ports) measures the concentration of dissolved oxygen in the fish tank. In case of low oxygen values, the solenoid valve opens and oxygen is transported into the water by the micro-bubbles - created by the ceramic oxygen diffusor.

Measurement of the pressure in the oxygen pipeline is here used to control the proper functioning. In case of an fault (e.g. oxygen bottles empty, oxygen generator failure, leakage), the user is alarmed.
