Pressure Sensor
F02 Safety Pressure Sensor
The F02 Safety is available for pressure ranges to 1,200 bar. The sensor signal is made available at two outputs in parallel, whereby the second output represents an inverted signal. Users can choose between a ratiometric and a 4-20-mA output in three-wire technology. Due to the two-channel architecture, it is possible for a downstream control unit to not only check the functionality of the F02 Safety, but also to monitor the signal path. This allows the use in safety-relevant applications, which require a Performance Level PL d, AgPL d or SIL 2. The maximum permitted media temperature range extends from -40…+125 °C. The total accuracy in the compensated range of 0…+80 °C lies at <= 1 % FS. The maximum possible flexibility during integration into an existing machine is ensured through the provision of a multitude of available pressure connections as well as the small construction. The electrical contact takes place either via a 5-pole M12 or a Deutsch DT04 connector.
- Pressure measurement range 10-1200 bar
- Operating temperature range -40-+85°C with media temperature up to 125°C
- Dual output signal, inverted
- Secure output, inverted
- Secure output as redundancy of analog current or ratiometric signal
- Ingress protection IP67
- Welded stainless steel measurement cell
F01 Safety Pressure Switch
The F01 is available for pressure ranges from 10 bar to 1200 bar and has two switching outputs which switch inverted to each other. Optionally, the F01 is also available in a version with one switching and one analog output. Here, the current output is read back by the F01 to ensure that the output signal is emitted correctly. To be able to use the F01 in as many applications as possible, users can select different pressure connections. The electrical contact takes place via a 5-pole M12 connector. Through the calibration of the transmitter via the temperature, a total accuracy of 1 % FS can be achieved within a range of 0…80 °C. The maximum media temperature totals +125 °C. The stainless steel parts coming into contact with media guarantee maximum media compatibility in combination with the welded thin-film measurement cell.

Redundant Encoders
SMX.igs-a
The robust inclination sensors of the SMX.igs-a series offer the user full IMU functionality. The accelerations and rotation rates in 3 axes are measured and output. The sensors also provide inclination values in all three axes. Depending on the sensor type, various configurable filter algorithms are available to the user to improve the stability of the measured values. In addition to Butterworth and critically damped low-pass filters, a Kalman filter can be activated for dynamic applications. This makes the sensor ideal for use in dynamic applications such as mobile machinery. The measured values are passed on to host control systems via a CAN, CANopen, CANopen Safety or SAE J1939 interface. The protocol and measuring range are freely selectable. The STW open source software platform openSYDE is also supported, enabling the sensor to be integrated quickly and easily into existing and new applications. Preconfigured projects and dashboards help with quick and uncomplicated commissioning of the SMX sensors. The robust die-cast housing with an M12 plug/socket combination completes the sensor.

IMU's and Inclination Sensors
Redundant Encoder
For the implementation of a safety function in accordance with e.g. Performance Level d or SIL 3, not all components necessarily have to meet the safety requirements directly. Often the required safety level can be achieved with redundant information and the appropriate control system. In concrete terms, our redundant standard encoders provide diverse (magnetic and optical) signals that are generated completely independently of each other, but can still be correlated with each other. Even the supply voltage is available separately for each sensor unit. Almost all safety-related control or monitoring systems have conventional inputs. This makes it possible to use inexpensive standard components with high-quality redundant encoders from a process-controlled assembly and to achieve the required safety level cost-effectively.

- High interference immunity
- High bearing loads: up to 220 N radial / 120 N axial
