Digital Sensors

Digital sensors are precalibrated sensored with an digital interface like I²C or SPI.
The internal structure includes a MEMS cell, amplifier, AD converter, DSP, ASIC and interfaces.

Current Sense Transformer

Current sense transformers use the principle of inductive coupling on a transformer to convert the input and output currents and voltages based on turns ratio. The current sense transformer features a primary winding with very few turns, often just one, and a secondary winding with many turns, ranging from tens to thousands. The current passing through the primary winding will induce a current in the secondary winding which can then be converted into a measurable voltage using a burden resistor as the load. Thus, the output voltage is directly proportional to the input current, making the current sense transformer an effective tool for current measurement. Although the current sense transformer is not capable of measuring DC currents, it will measure AC currents with the advantage of offering isolation, common mode noise rejection, accurate measurement and robustness.

Terminal Blocks

Terminal block connectors (TBL) provide a secure and reliable way to connect wires in mains line assemblies. They allow for quick installation, safe handling of high voltages, and flexible wiring options. Their robust design ensures durable connections industrial devices.

Current Sense Resistors

Current sense resistors are typically resistors placed in series with the circuit through which the current is to be  measured. When current flows through the circuit, a voltage drop occurs across the shunt resistor proportional to the current passing through it. In high-current applications, it can lead to significant power dissipation and heat generation, requiring additional cooling measures or derating of the resistor's power rating. They are typically used in battery management systems, power supplies and converters, motor control and devices.

IR Emitters & Detectors

Infrared emitters and detectors enable non-contact communication and sensing. They are suitable for e.g. remote controls, proximity sensors, and optical data links.

Signal LED

Signal LEDs provide clear visual indication of operating states, warnings, or activity in an electronic system. They are available in various colors and sizes, providing a simple and intuitive status display for users.

Short Introduction to Measurement & Sensing

A Sensor is a system that measures a physical dimension and converts it into an electrical signal. Sensors are  analog with infinite resolution, but data to and from  electronic devices is transferred digitally. Analog sensor values must therefore be digitized.

Conversion can be done thorugh a discrete AD converter when using an analog sensor like a Shunt or a Photo-Diode. Alternatively the conversion can be all done within the sensor when using a MEMS system.
