Xpzx temperature transmitter
Product No.: 194011-507 Product model: xpzx temperature transmitter Updated on: September 3, 2012 Producer: Shanghai Feilong instrument and Electrical Co., Ltd Product details Product Description: 1、 Overview The explosion-proof integrated temperature transmitter (hereinafter referred to as temperature transmitter) is composed of temperature sensor and signal converter. The signal converter is installed in the cold terminal junction box of the temperature sensor, which directly converts the voltage and resistance signals detected by the temperature sensor into 4-20mA current output. Simple structure, easy to install, use and maintain, it is a new generation of temperature detection and control instrument, which is welcomed by the majority of designers and users. At present, it has been widely used in petroleum, chemical industry, metallurgy, power station, light industry and other departments, with regulators, recording instruments, computers and other supporting use, forming a variety of measurement and control systems. According to different temperature sensors, the temperature transmitter is divided into two series: thermocouple and thermal resistance. In each series, it is divided into flameproof type and ordinary type according to different use occasions. According to different output functions, it is divided into field display and no field display. The user can choose the appropriate specification and model according to the use situation and the requirements of the supporting instrument. The explosion-proof temperature transmitter has passed the test of national instrument explosion-proof safety supervision and inspection station, and can be used in explosive gas environment. 2、 Main features 1. Two wire transmission. The two wires powered by the signal converter also transmit the output signal. 2. Output constant current signal (4-20mA). It has strong anti-interference ability and good remote transmission performance. 3. The signal converter is packaged into modules with epoxy resin, which has the advantages of anti vibration, corrosion resistance, moisture-proof, etc., and can be used in places with poor conditions. 4. The millivolt signal of thermocouple is directly converted into 4-20mA current output by signal converter, and the signal is transmitted by ordinary cable, which can save expensive compensation wire. 5. The temperature transmitter with on-site display not only outputs 4-20mA current signal, but also can read the measured temperature at the temperature measurement site, which brings great convenience to the operators. 3、 Main technical indicators Power supply voltage: 13-30v, DC Load resistance: 0 ～ 850 Ω Output signal: 4 ～ 20mA Basic error: ± 0.2%, ± 0.5% Display mode: bit LCD Operating environment temperature: - 20 ～ 70 ℃ Environmental temperature impact: 0.25% / 10 ℃ Cold end compensation error: 0.5% / 10 ℃ Explosion proof sign: D Ⅱ BT4 Protection grade: IP54 4、 Model and specification (download transmitter selection sample) 5、 System connection The general power supply voltage vs is 24V, and the load resistance RL is 250 Ω, so that when the circuit passes 4-20mA current, the voltage drop on RL is 1-5V. If other values are selected for vs and RL, the RL value cannot exceed the value calculated by the formula RL =. 6、 Boundary dimension and installation 1. Common integrated temperature transmitter (thermocouple, thermal resistance) 2. Flameproof integrated temperature transmitter (thermocouple, thermal resistance) 7、 Explosion proof characteristics 1. Explosion proof sign: diibt4 2. Place of use It can be used in the environment containing explosive gas mixture, and the explosion level is not higher than class II B (including class II a class II B), and the spontaneous combustion temperature is not lower than T4 (including T1, T2, T3, T4). The above is the detailed information of xpzx flameproof integrated temperature transmitter. If you have any questions, please call
