How PT-100 Sensors Work: A Comprehensive Guide
PT-100 sensors are a type of Resistance Temperature Detector (RTD) used for precise temperature measurement across a range from -200°C to 500°C. Composed mainly of a platinum element enclosed in a robust metallic or glass tube, these sensors exhibit a direct relationship between temperature and resistance, with resistance increasing as temperature rises. The “PT” denotes platinum, and “100” indicates its resistance value at 0°C. Available in three and four-wire configurations, PT-100 sensors enhance accuracy by compensating for resistance changes caused by wire length. Additionally, they come in various shapes, with options including head and non-head types.
Magnetic Bi-Stable Sensor By PROSIS
The content discusses two types of magnetic sensors: normal and bi-stable. Normal magnetic sensors, including reed switches, change their contact state based on proximity to a magnetic field but cannot distinguish between the poles of a magnet. In contrast, bi-stable magnetic sensors by PROSIS can identify north and south poles, having two stable states and retaining their contact state after the magnet’s removal. They are utilized in lift systems to detect floor levels by recognizing the alternating magnetic poles. Specifications for the bi-stable sensor include power supply options and dimensions, highlighting its functionality and applications significantly.
Proximity sensors | Sensing the objects nearby !
Proximity sensors are devices that detect the presence of nearby objects or materials without direct contact, generating an electrical signal. They are categorized into three main types: inductive sensors, which detect metals using electromagnetic induction; capacitive sensors, capable of sensing non-metallic objects like liquids and powders by measuring capacitance changes; and magnetic sensors, which respond to magnetic fields. Despite their different mechanisms, these sensors share similar wiring configurations, typically operating on a DC supply voltage of 10 to 30 VDC. They are available in 2, 3, and 4-wire configurations, each with distinct functionalities.
How Pressure Transducers Work: Principle, Types & Applications
A pressure transducer converts pressure into an electrical signal, facilitating alarm systems and output control. The focus here is on the Cerabar PMP135 by Endress+Hauser, which employs a metallic diaphragm and fluid to generate electrical signals via an electronic strain gauge. This compact and hygienic sensor supports easy installation and is suitable for various cleaning processes. It functions within a temperature range of -10°C to 100°C and outputs a 4-20 mA current for PLC input, allowing real-time pressure monitoring. The transducer maintains a proportional relationship between current flow and pressure readings, enhancing operational efficiency.
