Inductance - Import export

Inductive proximity switches are contact-free sensors. They detect all conductive metals, regardless of whether they move or not. The achievable sensing range of the devices depends on the object material and its dimensions. The vibration-resistant sensors can be approached laterally or frontally. Inductive proximity switches are used for presence detection (e.g. goods carriers), positioning (e.g. dampers), counting (e.g. nuts /bolts), speed detection (e.g. for cog wheels), on conveyor systems (e.g. hose feedings) or distance measurements (e.g. press-in checking) of metallic objects.

Inductive sensors detect metal objects contactless and wear-free. For this, they use a high-frequency electromagnetic AC field that interacts with the target. Their strengths are the enormous durability, reliability, high switching frequencies and a long service life. Through a unique coil concept the uprox® sensors offer the highest switching distance, factor 1 for all metals and, right from the start, the highest operational safety through simple and safe installation.

The inductive coupler of the NIC series is designed for contactless bidirectional transmission of power and data. The devices consist of two components, the primary part NICP and the secondary part NICS. The primary part supplies the secondary part with power via the air interface. In return the secondary part provides data to the connected sensors and actuators.

The inductive linear position sensors of the Ri series operate contactless and wear-free according to a new, revolutionary measuring principle: The angular position is not detected via a positioning magnet but via an oscillating RLC circuit. The sensors are thus completely immune to magnetic fields such as generated by large motors for example. The measuring range of the rugged angle sensors is 360°. As starting variants analog voltage or current outputs and switching outputs are available.

With the Therma friction thermocouple you can determine the surface temperature of the brakes while driving. Attaching the mounting adapter puts uniform pressure on the brake disc through the spring-loaded sensor by using a bayonet cap. That perfectly compensates movements caused by centrifugal force and vibrations as well as the volume decrease caused by disc wear while ensuring a valid measurement. The brake disc friction sensor measures the surface temperature of the brake disc. It imparts important insights about the temperature development. That enables an indication about the brake line, intake and temperature radiation. A brake disc that becomes too hot during a race massively loses its effectiveness and deceleration to the accustomed and optimal degree is no longer possible. If the temperature is too high, the brake pads start gassing on top of that.

CSN® Current Sensors are used for current measurement in control and protection systems in power transmission links (AC and DC applications). The CSN® type Current Sensors are based on highaccuracy resistive sensors (shunt) respectively iron free cores (CSN® AirCoil). There are selfsupporting structures available where the CSN® Current Sensor is mounted on top of a composite insulator, as well as variants in which the CSN® Current Sensor will be mounted hanging in the busbar. Schniewindt has implemented CSN® Current Sensors for nominal currents of up to 5 kADC at system voltages of 800 kVDC, which have been successfully typetested. Also for the precise measurement of small currents (1 to 10 A), such as transient currents in capacitor banks, Schniewindt offers appropriate solutions. All of our CSN® Current Sensors are individually designed according to customer requirements.

The sheathing thermocouple from Therma is perfect for reliable and fail-safe temperature measurement in the exhaust gas system. It excels with its simple structure. By selecting double-walled sheathing material made of Nimonic75, this thermocouple is well prepared for corrosion influences and vibrations along with extremely high temperatures. Furthermore, assembly with a compression-type fitting lets you decide the installation length onsite. Sheathed thermocouples NiCr-Ni, Type “K”, Class 1

This sensor for measuring exhaust gases was developed together with a Formula 1 team. The goal was to achieve the greatest possible reliability during the race. The sensor was designed so that it can withstand a maximum of vibrations and extreme temperatures while being made in a highly compact construction at the same time. The special feature is the connection lead. It is not made from the usual mineral-insulated stainless steel sheathed line, which is too rigid and which tends to vibration fractures. Instead, the line is made of stranded conductors with PTFE insulation and an additional heat shield so it can be easily and flexibly adapted to the environment. The sensor is being used with exceeding success by professional teams in long distance races, American race series and the domestic DTM. The benefits: Highly vibration-proof Very robust High temperature resistance (up to 1,200 °C) Individual plug assembly possible Can be individually adapted

This plug-in sheathing thermocouple is recommended for measuring the temperature in the exhaust gas flow. It is genuinely multipurpose, mounting with the cap nut means the thermocouple does not need to be rotated, which simplifies installation and fast replacement. In addition, it has “motor sports genes” such as vibration resistance, fast response time and high temperature resistance. The benefits: Vibration-proof Fast response time High temperature resistance (up to 1,200 °C) Various installation lengths can be supplied With cap nut Sheathed thermocouple NiCr-Ni, Type “K”, Class 1

The braking fluid thermocouple from Therma convinces not only with its compact construction but also with its simple installation. Just screw it in in-place of the air vent screw to measure the temperature of the brake fluid. The subsequent sheathing line can then be comfortably bent in the required direction. When the thermocouple is screwed in, the braking system is then vented through its thread. The temperature measurement of the brake fluid, along with the brake disc surface measurement, also supplies important control values for a successful and safe race. During long races or races with many downhill routes, the brake disc overheats over-proportionally. The accruing radiation heat during this has a direct effect on the brake fluid, respectively heats it up. Depending on the type of brake fluid being used, it already reaches its boiling point at approx. 140–260 °C.

The infrared temperature sensor from Therma is perfect for measuring the current tyre temperature. The temperature of the tyre and thus the associated effects are decisive factors for success in motor sports. The tyre pressure is strongly temperature-dependent. The measurements collected by the sensor permit conclusions to be drawn for ideal vehicle tuning. Large fluctuations have a direct effect on the vehicle performance and the service life of the tyre.
