TME – Universelle Stäubli oscilloskop prober
Det anerkendte brand Stäubli er primært kendt som producent af højkvalitetskonnektorer, især til måleapplikationer. I dag omfatter leverandørens sortiment også et udvalg af oscilloskopprober, som for nylig er blevet tilføjet til TME’s katalog.
(Engelsk) Performing precise measurements with an oscilloscope largely depends on the quality of the probes used. The signal transmission from the measurement point to the device should be done with minimal, preferably negligible distortion. However, in many cases, this is not the only factor to consider during tests. Equally important is safety, which requires special attention when probing circuits with significant voltage, especially AC. The best examples here are power grid installations and devices powered by them.
Stäubli oscilloscope probes Stäubli are designed to allow such work, as well as with precision and compliance with commonly accepted standards, allowing them to be used with measurement devices from any manufacturer. These products belong to the Isoprobe II and Isoprobe III series.
We invite you to familiarize yourself with the new assortment.
In this article, we discuss topics such as:
- Safety and parameters of Stäubli oscilloscope probes
- Precise and interchangeable measurement tips
- Caps that help reduce interference
Oscilloscope probes
Stäubli probes meet the requirements of CAT III and IV standards in ranges up to 1000V RMS. This means they can also be used for testing electrical installations (e.g., taking measurements in network circuits and distribution boards) and devices such as industrial or consumer machines (RTV/AGD equipment). The design of the probes ensures proper insulation distances comply with IEC/EN 61010-031:2015 standard. Moreover, many of the supplier’s probes can work with signals with a frequency exceeding 450MHz.
The manufacturer’s assortment includes passive high-frequency (HF) test probes and accessories – it should be emphasized that most products are supplied with accessories included. These may include (depending on the chosen item):
- interchangeable, colored caps used to identify the tip;
- crocodile clips for ground connection;
- insulated clamps for wires;
- precise tips;
- caps.
All probes are equipped with insulated BNC connectors, i.e., plugs commonly used in oscilloscopes.
For electronics technicians and electricians testing waveforms in network circuits and connected devices, an important part of the offer are probes equipped with voltage dividers. They come in ratios of 10:1 and 100:1. They allow safe connection of circuits from the upper limit of low voltage (up to 1kV AC) to the inputs of standard oscilloscopes.
Measurement tips
A practical accessory for oscilloscope probes are caps with measurement tips. They allow changing the probe contact to one of the standards used in metrology. From the TME catalog, you can purchase 4-millimeter and 2-millimeter versions. The former have banana plug width, are compatible with such connectors, and thus with a range of other accessories, e.g., crocodile clips or multimeter sockets. The caps are available in several color variants and, like the probes, meet the CAT II 1000V standard requirements.
Cap with reference contact
The cap with a reference contact has an additional lead, the reference contact, connected to the measurement circuit ground and the shield of the cable and probe. Such a connection, placed close to the measurement tip, improves the accuracy of digital and pulse signal testing, characterized by high frequency, reducing distortion and noise, especially when using long cables. The contact of the cap has a relatively short lead, so it provides better results than the classic alternative, which is an auxiliary connection with a flexible wire and crocodile clip.
