RTD temperature sensor applications: baked oven, Steam oven,Grill,Industrial Oven, Air compressor, Temperature-measurement Instrument, Heat meter,New energy motor
The precision of each pair of temperature probes after pairing may meet the error of 0.1°C, and each pair of temperature sensors for the heat meter series industrial temperature sensors conforms to the criteria of Chinese standard CJ 128-2007 and European standard EN 1434 in terms of error range. To avoid MIS installation due to the length of the cable, the two ends of the probe are each marked with a red and blue marker. Upper water is at the red end, while lower water is at the blue end.
The product has excellent characteristic stability and consistency, high-temperature measuring accuracy, wide temperature measurement range, good moisture resistance, and high reliability.
The Y60 series platinum resistance sensor uses two-wire or three-wire silver-plated Teflon wire, which offers high-temperature measurement precision and strong dependability. This series is packaged in 304 stainless steel or PTFE Teflon rubber.
The Seibel effect is the basis for the thermocouple temperature sensor, which measures temperature. Current will flow through a closed loop formed by the two separate homogeneous conductors A and B when there is a temperature differential (T-T0) between the ends of the loop. By sensing the potential created by the current, the thermocouple temperature sensor determines the temperature of the hot spot being monitored.
One of the popular types of sensing components used to measure temperature in industrial applications are thermocouple temperature sensors. They are chosen from a variety of sensors, including semiconductors, resistance thermometer detectors, and thermistors (RTDs).
The most often used temperature sensors are thermocouple devices. This is due to the fact that thermocouples exhibit steady performance, a broad temperature measuring range, long-distance signal transmission, etc. They also have a straightforward structure and are simple to operate. Thermocouples make display, recording, and transmission simple by directly converting thermal energy into electrical impulses.
A loop is created by joining two wires with various components (known as thermocouples wire or thermodes). The pyroelectric effect is a phenomena where an electromotive force is produced in the loop when the junction's temperature varies. The thermoelectric potential, often known as the Seebeck effect, is the name given to this electromotive force.
The DS18B20 does not require an external power source to function. The device is powered when the data line DQ is high. The internal capacitor (Spp) charges when the bus is pulled high, and the capacitor powers the device when the bus is pulled low. "Parasitic power" is the term used to describe this method of 1-Wire bus device powering.
The temperature readings from the DS18B20 temperature sensor are 9-bit (binary), suggesting that the device's temperature data is either sent to the DS18B20 temperature sensor via the single-line interface or that it is sent out from the DS18B20 temperature sensor. As a result, just one line (plus ground) is required to connect the host CPU to the DS18B20 temperature sensor, and the data line itself can act as the sensor's power source in place of an external power source.
The DS18B20 is a popular digital temperature sensor with the features of small size, minimal hardware overhead, strong anti-interference capabilities, and high precision. It outputs digital signals. The DS18B20 digital temperature sensor is simple to wire and is packaged in a variety of ways, including pipeline, screw, magnet adsorption, stainless steel, and numerous model options.
The 1-Wire bus protocol, which is utilized by the DS18B20, only needs one control signal for communication. To avoid the bus port being in a 3-state or high-impedance condition, the control signal line needs a wake-up pull-up resistor (the DQ signal line is on the DS18B20). The microcontroller (master device) in this bus system recognizes the bus's devices by their 64-bit serial numbers. A bus may potentially support a limitless number of devices because each one has a distinct serial number.
