Encoders with SSI interface – an excellent choice

Absolute encoders with SSI interface are utilized in many fields of application. The position value is transmitted bit by bit in a serial manner by the SSI interface straight from the encoder.


Encoders with integrated bus interface

Absolute encoders by Baumer are available with all common interfaces. For a most compact design the interface is integrated in the encoder itself.


Encoders with modular bus covers

Many absolute encoders by Baumer are available in a modular concept where the bus cover accommodating the required fieldbus interface is simply docked to the basic encoder.


Stainless steel and explosion-proof encoder confugurations

Baumer provides a wide a range of explosion-proof encoders and analog tachogenerators – for example with zone 22 approval or in pressure-proof encapsulated designs in line with ATEX 95.


Encoders with parallel interface – the well-proven concept

Absolute encoders with parallel interface transmit the respective angular position to the evaluation electronics as data word in a unique code.

High performance meets compact design: Baumer encoders with integrated fieldbus interface are a class of its own –though miniature in design, they meet the most demanding requirements and convince by performance, features and easy operation.

Pioneering also in this field, for many years now Baumer has been offering absolute encoders featuring all common fieldbus interfaces. Baumer has acquired profound expert know-how and is active in the respective user organisations. The most common fieldbus interfaces are Profibus-DP, CANopen, DeviceNet, Interbus and EtherCAT as well as customer-specific protocols based on RS485 like SLIN or CANopenLIFT. Baumer also offers configurations combining two different bus interfaces in the same device as a two-in-one solution.


Incremental encoders

Incremental and sine encoders are the vital link between periphery equipment and control in mechanical motion feedback systems. Encoders convert rotary motion into incremental or sine signals for electronic evaluation to enable motor speed feedback and position monitoring.

The Baumer product range covers micro-sized configurations (MICRO series) up to large hollow shaft diameters. Innovative sensing methods and mechanical designs ensure precise measuring results and versatile solutions – from motor feedback systems to HeavyDuty configurations, from standard to customized products.

Baumer Process Instrumentation

In the Product Segment Process Instrumentation Baumer unites the extensive knowledge and expertise of leading names in the field of process instrumentation:


Since 2007 the former Bourdon-Haenni Group operates as Baumer in the market.

Within our product segment Process Instrumentation you can find a broad range of electronic and mechanical products and services:

  • Electronic and mechanical Pressure Instruments
  • Electronic and mechanical Temperature Instruments
  • Level Instruments
  • Force and strain sensors
  • Conductivity Measurement


Baumer has a wide experience in electronic as well as mechanical pressure measuring instruments.

As the inventor of the Bourdon Tube-Principle Baumer Process Instrumentation (formerly Bourdon-Haenni) is a proven expert in the field of high-end manometers.


The broad product range contains first-class solutions (MEX5/MEX3) for demanding environmental conditions as in the petro-chemistry or in salt-water applications. In addition, we develop special solutions like for example for military and civil aeronautics or ship building. Many EPC-Contractors value Baumer as a competent partner for process instruments for the construction of refineries, power plants or water treatment plants.

With our electronic pressure transmitters we are in the unique situation to master four different pressure technologies. This allows us to offer the ideal solution for almost all applications.

Level Measurement

In level measurement we distinguish between continuous measurement and limit detection. The requirements to the measuring solution for solid material are different to solutions for liquids. In addition, it is important whether the measurement is with or without contact with the media.


Besides the geometric conditions there are other influencing factors such as foam, turbulences and other chemical-physical circumstances. In addition, there are requirements regarding mounting, cleaning as well a precision and costs. The main task is to chose the right technology for the specific need. Thanks to our broad technology competence we are able to offer you the right solution for your application.

We also offer you the possibility to detect the leakage of liquids in a secure and reliable way. The integrated circuit of the sensor provides failsafe action in case of a cable break or sensor failure.

We provide the ideal solution for media separation (e.g. beer/water, CIP- dissolutions) or media mixing.


If conductivity in liquids has to be measured like in the food and beverage industry or in the water treatment or enrichment of cleaning agents, the temperature compensated Baumer conductivity sensor guarantees reliable measurement values.

14 switchable conductivity ranges compensated with 7 temperature ranges enables an accurate, qualitative control of the process. In the device both values will be displayed by a protected glass window. Each measured value has an isolated analogue signal output of 4…20 mA available. Four preset measuring ranges can be chosen by an external controller, for example, depending on the recipe specification.
