Cable Assembly for Household Electricity

RTD (Resistance Temperature Detector) is a sensor whose resistance changes as its temperature changes. The resistance increases as the temperature of the sensor increases. The resistance vs temperature relationship is well known and is repeatable over time. An RTD is a passive device. It does not produce an output on its own. External electronic devices are used to measure the resistance of the sensor by passing a small electrical current through the sensor to generate a voltage. Typically 1 mA or less measuring current, 5 mA maximum without the risk of self-heating.

Stainless Steel Float Switch Sensor for Liquid Level Float liquid level switch is mainly composed of a dry reed tube and a floating ball, the magnetic material in the float, the float moves up and down with the measured liquid level, touching the dry reed tube action and detecting the liquid position.The product has the characteristics of light volume, simple working principle, high reliability and low price;A variety of materials for selection, and suitable for a variety of different liquid environment;Can be directly connected to electronic controllers, relays or contactors;The performance is stable and reliable, the water level can reach +/-1mm; Key Parameters: Typical Applications Advantages: Typical Sizes: Ordering Code: Flexible Custom Design &Development Welcomed.  Contact us now for more details or for your sensing solutions

This sensor is essentially a reed switch, encased in an ABS plastic shell. Normally the reed is 'open' (no connection between the two wires). The other half is a magnet. They're often used to detect when a door or drawer is open, which is why they have mounting tabs and screws.
