Do you have a specific task? We will get back to you with a recommendation.
We develop the electronics that turn a sensor into a measuring system: amplifiers matched to the design and the signal, electronics inside the transducer, and wireless or telemetry solutions for measuring points that no cable can reach.
Mechanics, sensors and electronics are under one roof here. We machine the spring element ourselves, apply the strain gauges ourselves, and calibrate in our own lab. That way the electronics can be designed together with the sensor instead of being adapted afterward.
What we develop
matched to design, accuracy and measuring speed – from a miniature board to a DIN rail housing
amplifier, microcontroller and interface sit in the sensor; out comes a finished signal instead of millivolts
compact intermediate amplifiers when there is no room at the measuring point or it gets too hot
cable-free transmission from rotating shafts and from moving or freely suspended parts
microcontroller programming for filtering, preprocessing and bus communication right at the sensor
for safety-related applications up to SIL 3 / PL e, see functional safety
Interfaces
The signal goes where it is needed: to the controller, a data acquisition card or a computer.
- Analog: 4–20 mA, 0–10 V, ±10 V or ratiometric in mV/V
- Serial: RS485 and RS232
- Fieldbus and industrial Ethernet: CANopen, PROFINET, EtherCAT, Modbus TCP
- IO-Link with diagnostics, directly in the cell – see how IO-Link works
- Wireless, when no cable can be run
From our projects
- Wireless load shackle for 250 kN: electronics and battery sit on the pin head, and readings go to the receiver wirelessly and in real time.
- CANopen in load cells: the evaluation sits in the transducer, several cells share one line and each stays visible on its own.
- Compressor shaft: inductive telemetry carries the signal off the shaft and powers the electronics on it at the same time.
- Biaxial load pin for 220 kN: two measuring bridges in the pin, each axis with its own 4–20 mA channel.
How a project runs
- Define the requirements: sensor and signal, installation space, environment, interface and quantity.
- Circuit and layout: schematic and board, fitted to the existing geometry.
- Firmware: signal filtering and communication with the controller.
- Samples and testing: build the first samples and test them in operation.
- Installation and calibration: fit the electronics into the transducer, adjust it and calibrate the measuring chain to ISO 17025.
When it already exists
Not every task needs a development project. Weighing transmitters, indicators and strain gauge amplifiers are under measurement electronics, amplifiers with IO-Link under IO-Link amplifiers.
