High-quality customized sensors, thermal switches, and fuse services
Thermal switches (siguranță termica) and Temperature Sensor have to work in a fail-safe manner under any circumstances. Their natural operating environment includes cold, heat and humidity.
A thermal cutoff is an electrical safety device (either a thermal fuse or thermal switch) that interrupts electric current when heated to a specific temperature. These devices may be for one-time use (siguranță termica), or may be reset manually or automatically ( comutator termic).
A temperature sensor is a device that detects and measures hotness and coolness and converts it into an electrical signal. At YAXUN, we design and manufacture a broad portfolio of temperature sensors – including our NTC thermistors, RTD-uri, PT100/PT1000, and Ds18b20 – designed for efficiency and easy installation, with capacity to reliably integrate technology that responds to human behavior.
temperature sensor probe
Temperature probe assembly are used to make measurements of air, liquid or surface temperatures and are available in various forms such as thermocouple, termistor (NTC) and PT100 to complement thermometers and temperature data logging instrumentation.
Thermal cut-off switch
A thermal switch is an electromechanical device which opens and closes contacts to control the flow of electrical current in response to temperature change. This thermal cutout (Automatic/manual reset) has a bimetal strip and a beryllium copper blade and the operating mechanism is based on the snap action disc thermostat (NC/NO).
Thermal fuse & current fuse
Unlike electrical fuses or thermal fuses, thermal fuses only react to excessive temperature, not excessive current, unless the excessive current is sufficient to cause the thermal fuse itself to heat up to the trigger temperature. A thermal fuse is like a mechanical switch that is spring-loaded to stay in the open position. An electrical fuse is essentially a thermal fuse with a well-established resistance and dissipation profile, and the current at which it fuses
Fuse boxes and fuse holders
Automotive/electrical fuse holders/boxes are holders used to install fuses, and their broad categories can be divided into: panel-mounted fuse holders, PCB-mounted fuse holders, lead-type fuse holders, rail-type fuse holders and automotive fuse holders. The fuse box is a box used to install fuses and has performance characteristics such as waterproof, fireproof, and high temperature resistance. According to different materials and shapes, fuse boxes can be divided into lead-type fuse boxes and fuse holders.

Terminologia parametrilor termistorului PTC
Heating & Temperature Control and PTC Thermistor Parameter Terminology for Overcurrent Protection
Ambalarea și selecția senzorului cu termistor NTC
La selectarea unui termistor, este într-adevăr necesar să se ia în considerare în mod cuprinzător mulți parametri cheie și ambalaje (Încapsulare cu rășini epoxidice, Încapsulare cu mărgele de sticlă, Încapsulare cu peliculă subțire, Încapsulare SMD, Senzor sonda din otel inoxidabil Incapsulare, acoperire prin turnare prin injecție). Să vă spun în detaliu:
Domeniul de rezistență și aplicarea termistorilor
Gama de rezistență a termistorilor este largă, iar rezistența termistoarelor NTC poate varia de la zeci de ohmi la zece mii de ohmi, si chiar si dispozitivele speciale pot fi personalizate in functie de necesitati. Valorile de rezistență utilizate în mod obișnuit sunt 2,5Ω, 5Oh, 10Oh, etc., iar erorile comune de rezistență sunt ±15%, ±20%, ±30%, etc. Gama de rezistență a termistorilor PTC este de obicei de la 1KΩ la sute de KΩ.
Precizia și timpul de răspuns al senzorilor cu termistor
Dispunerea rezonabilă a senzorilor de temperatură: Locația și aranjarea senzorilor de temperatură vor afecta, de asemenea, timpul de răspuns. Dacă aria de contact dintre senzor și obiectul măsurat este mare, schimbul de căldură va fi mai rapid și timpul de răspuns va fi în mod natural mai scurt. Cu toate acestea, Vă rugăm să rețineți că o suprafață de contact prea mare poate duce, de asemenea, la erori de măsurare crescute, așa că trebuie să facem un compromis bazat pe situația reală.
Mai multe cazuri de aplicare ale senzorilor cu termistor
Ca componentă care poate modifica valoarea rezistenței în funcție de schimbările de temperatură, termistorii au o gamă largă de aplicații (cum ar fi măsurarea temperaturii, controlul temperaturii, compensarea temperaturii, alarma de temperatura, protectie termica a bateriei). Permiteți-mi să vă împărtășesc mai multe cazuri de aplicații ale termistorilor:
Cablajul senzorului de temperatură cu termistor NTC
Metoda de conectare a senzorului de temperatură cu termistor NTC trebuie determinată în funcție de scenariul real de aplicare și cerințele de măsurare. În timpul procesului de cablare, asigurați-vă că acordați atenție polarității pinului, selecția firului, interval de temperatură, filtrare si decuplare, tratament de împământare, și verificarea și calibrarea pentru a asigura acuratețea și fiabilitatea măsurării.
