Electricity is the most widely used modern society, secondary energy, power industry is related to the national economy and the importance of basic industries and utilities. Previously in the power production process, the temperature measurement and control of people is not enough attention, not even pay attention to this problem. Distribution room until some power stations, transformers stopped working due to high temperature, some of fire or other accidents (such as the vulnerability of electric shock, explosion, etc.), resulting in a large area power outages, so that enterprises can not be normal production; there Some large industrial areas and large enterprises due to high temperature distribution cabinet, resulting in accelerated aging lines, wire peeling, melting wires short-circuit, causing shutdown or accident. Therefore, people gradually realized the importance of temperature measurement and control, accurate measurement of temperature on power output quality, production efficiency and reliable operation is essential. In the 90 years before, due to technical limitations, the power of temperature measurement tool is the thermocouple, the thermoelectric heat resistance type temperature sensor, but these sensors have different degrees of impairment: the low measurement range, measurement is not accurate, poor performance short service life, etc., often have to repair and replacement, to the enterprise’s production brought a lot of inconvenience. With advances in technology, infrared sensors there, Shenzhen Hibill Electronics Co. Hai Beier infrared thermometer also came into being in 1999, the brand products by the majority of customers love and appreciation for the production of electricity customers or major equipment to monitor and control the temperature accurately.

Hibill infrared temperature sensor of the principle and advantages

Infrared, is the radiation wavelength is approximately 0.75-1000mm range of the electromagnetic spectrum,  Hibill license the use of infrared thermometer is the 8-14μm infrared wavelength response band, the band effectively weakened the atmospheric dust and water vapor on the infrared emission attenuation, reducing the ambient temperature output signal drift caused by mutations. The physical nature of infrared radiation is heat radiation, when the body temperature is above absolute zero, its internal thermal motion of charged particles will emit infrared out. The higher the temperature of objects, the infrared radiation will be out of the more infrared radiation, the stronger the energy. Infrared sensor is based on the energy of infrared radiation the object size and wavelength distribution, and the correspondence between surface temperature and the object itself by measuring the energy of infrared radiation, to accurately determine the object’s surface temperature. Traditional thermocouple, RTD and other conventional temperature sensors, infrared sensors, temperature range, long life, reliable performance, fast response. In addition, the infrared sensor is also particularly suitable for measuring corrosive media and the temperature of moving objects, and will not damage to the measured object temperature, are widely used in various sectors of the temperature measurement and control. In recent years, as with the company’s development efforts and R & D engineers, Shenzhen Bell Electronics infrared drying temperature sensor type constant increase, can be described as full range, handheld and on-line, and its performance continued to improve its scope is to cover low, medium and high temperature of different sections. Now more self-developed high-precision color High-temperature thermometer.

Hibill infrared temperature sensor in power facilities and process measurement and control applications

Shenzhen Hibill Electronics HBIR series produced miniaturized infrared temperature sensor (see Figure 1), the temperature range is -20 ℃ ~ 1800 ℃, accuracy of reading ± 1%, repeatability ± 0.5% of reading , the response time is 200-500ms, protection class IP65, the range in ambient temperature -20 ℃ ~ 75 ℃ and relative humidity of 10-90% in the use of the environment, and can output a variety of digital, current, voltage or thermocouple signal. And process monitoring and control in electric power facilities, mainly used for real-time measurement of non-contact mode the boiler air preheater, bus, major circuit breakers, motor bearings, motor windings, transformer windings, U cable connector of the temperature, and is used to detect equipment Hot or connection failure, etc., or equipment to the power system diagnosis, repair and maintenance of the state, for the power to safe, reliable operation and a steady supply of quality and quantity provides an important protection.
