Şok Direnci

Genel olarak Reed Anahtarları 100 g’a kadar yüksek şok direnci sağlar. Yine de sert bir yüzey üzerine düşme birkaç 100 g büyüklüğünde şok yaratabilir ki, bu da kontaktların ayarlarının bozulmasına yol açabilir. Düşürülen anahtarlar kullanılmadan önce hassaslık bakımından yeniden test edilmelidir!

Reed Anahtarlarını keserken ve eğerken yapılacaklar ve yapılmayacaklar

Terminallerin yanlış eğilmesi ya da kesilmesi ağır mekanik stres sebebiyle yapıştırma alanında çatlaklara yol açabilir. Bu sorunun önüne geçmek için terminalin cam gövde ve kıvırma, sırasıyla kesmenoktası arasında kalan  geri kalan kısmı çok sıkı tutulmalıdır.

Modifiye edilmiş Reed Anahtarlarının Boyutları

Terminalleri hemen hemen tüm şartlara uygun olacak şekilde modifiye edilmiş Reed Anahtarları tedarik ediyoruz. Boyutlandırma aşağıdaki örneklere göre yapılmalıdır.

Level Sensors are available in Form A- and Form B-Variants.

Form A means that the switch is open when the float is on the bottom of the stem (means tank is empty) and closed when the float is on the top of the stem (tank is full).

Form B means that the switch is closed when the float is on the bottom of the stem (means tank is empty) and open when the float is on the top of the stem (tank is full).

If you need to know if your tank is empty or the liquid reaches a low level (e. g. to refill coolant or lubricant) than a Form B Level Sensor is used.

If you need to kniw if your tank is full or nearly full (e. g. to activate a pump for emptying the tank) than a Form A Level Sensor is used.

Mounting

In general all oour Level Sensors are suitable to be either mounted from top or from the bottom of a tank. If you mount a Level Sensor from the bottom, with the stem directing up, the switching behavior will change (Form A will become Form B and vice versa).

Our standard hosuings are made from ABS, PA (Polyamide), PP (Polypropylene), nickel plated brass or stainless steel. Of course we are ready to povide costomized solutions with other materials as well.

The above mentioned data is intended only as a guide for chemical compatibility. We do not assume any liability for the accuracy of the information. It is strongly recommended that users perform their own tests to determine suitability of material.

We provide assistance to select the suitable magnet for your sensor application. Please take a look at our overview of prime magnet materials available.

Magnet Glossary

Anisotropic Magnet material having a preferred direction of magnetic orientation

Bonded Magnets Magnet powders mixed with polymer carrier; mechanical properties reach from elastic to hard; penalty of bonded material is a "weaker magnet" compared to non-bonded material

Coercivity Hc [kA/m] Demagnetizing force necessary to reduce polarisation J (HcJ) or induction B (HcB) to zero

Curie Temperature Temperature at which a magnet is totally demagnetized

Energy Product BH max [kJ/m3] Point on the second quadrant of the hysteresis loop at which the product of induction B and magnetizing force H reaches a maximum; describes the "strength" of magnet material

Gauss Unit of magnetic flux density in the CGS system (1 Gauss = 10-4 Tesla)

Isotropic Magnet material with no preferred orientation; can be magnetized in any direction

Magnet Pole "Output" of the magnetic flux

Oersted Unit of magnetizing force in the CGS system (1 Oersted = 0.0796 kA/m)

Remanence Br [mT] Residual induction in magnet material after being magnetized to saturation

Tesla Unit of magnetic flux density in the SI system (1mT = 10 Gauss)
