TDK Introduces its New EPCOS Pressure Transmitters

TDK has expanded its portfolio with new EPCOS pressure transmitters whose performance profiles are specially tailored to the requirements of industry 4.0.

TDKThese low-profile pressure sensors are characterized by their compact design, high accuracy and excellent long-term stability.

Big Data is the prerequisite for industry 4.0 solutions and processes.

The basis for generating the required data in industrial processes and environments are the various types of sensors.

The demand for pressure sensors and transmitters is increasing accordingly.

The leading basic pressure sensing technologies for MEMS are based on the piezoresistive and capacitive principles. While the latter is mainly suitable for consumer applications, the strengths of the piezoresistive principle are especially important for automotive and industrial applications. Piezoresistive pressure sensors excel in terms of the following key performance parameters:

  • High absolute accuracy
  • Low temperature coefficient
  • Low temperature hysteresis
  • High robustness against different media
  • High long-term stability

Absolute, gauge and differential measuring methods are used for a wide variety of tasks and requirements in industrial pressure measurement.

These methods can be realized particularly well with piezoresistive MEMS technology.

Ultra-flat and networkable

A new series of low-profile pressure transmitters specially designed for industry 4.0 applications features an extremely flat insertion height of only 6 mm and a footprint of 24 x 26 mm with feedthroughs for simple, maintenance-friendly screw mounting (Figure 1).

This transmitter series is designed for a wide range of maximum rated pressures from 16 mbar to 7 bar FS (full scale).

In the temperature range from -25 °C to +85 °C it achieves an accuracy of ±1 percent FS. The transmitters can be used for a wide range of applications, and they offer an accuracy of ±1 percent FS (full scale). Installation is very simple, as only two screws are required. The integrated SPI interface (serial peripheral interface) with a resolution of 16 bit enables simple implementation in digital industry 4.0 architectures.

Thanks to the two connectors integrated in the transmitters, they can be easily networked in daisy chain topologies. These transmitters are optimized for differential pressure measurement that, for example, is used in the predictive maintenance of filter systems, pump control or gas flows.
