Supply WZP-231 Integrated Temperature Transmitter Temperature Transmitter Sensor

500mm insertion depth within, or user requirements on demand, and other specifications prices are negotiable! 1. Overview: WZP-231B series of temperature sensors thermal resistance as the temperature measurement devices, the output signal from the temperature measurement devices. The temperature sensor can be widely used in petroleum, chemical, textile, rubber, building materials, electricity, metallurgy, medicine, food and other temperature process control or field, especially for the computer control system. 2, the working principle: thermocouple or RTD sensors measured temperature is converted into electrical signals, then the signal into the input of the transmitter network, the network consists of zero and thermocouple compensation and other related circuitry. After zero signal is input to the operational amplifier for signal amplification, the amplified signal all the way through V / I converter to calculate the after-treatment 4-20mA DC current output; another path after the A / D converter handles the meter display. Linear circuit has two transmitters, are used in feedback mode. Thermal resistance of the sensor, with positive feedback correction, thermocouple sensor, with multi-segment broken line approximation method to be corrected. Integrated digital display temperature transmitter has two display modes. LCD display temperature transmitter with two-wire mode output, LED display temperature transmitter output with a three-wire mode. 3, the technical parameters 1, input signal: Thermocouple: K, E, J, B, S, T, N. RTD: Pt100, Cu50, Cu100 (three-wire, four-wire system). Intelligent temperature transmitter input signal can be set via the handheld device and the PC arbitrary; 2, the output signal: 4-20mA DC output signal within the range, with thermocouple or RTD input signal into a linear or with temperature linear. Smart Temperature Transmitter output 4-20mA DC signal while superimposing the HART protocol communication standard; Isolated Temperature Transmitter: input and output are isolated, isolation voltage of 500V, increased resistance to common mode interference, even more suited to the computer network use; 3, the basic error: 0.2% FS, intelligent 0.1% FS; 4, wiring: two-wire, three-wire, four-wire system; 5, Display: four LCD display field temperature, intelligent four LCD can be set so that the display field temperature sensor, the output current and percentage of any one of the parameters via a PC or handheld device; 6, the working voltage: Common Model 12V-35V, intelligent 12V-45V, rated working voltage as 24V 7, allows the load resistance: 500Ω (24VDC power supply); limit load resistance R (max) = 50 (Vmin-12), for example, rated working voltage 24V, the load resistor can be selected within 0-600Ω range. 8, the working environment: a: Ambient temperature -25- + 80 ℃ (conventional type) -25- + 70 ℃ (digital display type) -25- + 75 ℃ (Smart) b: Relative humidity: 5% -95% c: the mechanical vibration f≤50Hz, amplitude ≤0.15mm d: non-corrosive gas or similar environment; 9, the environmental impact factor: δ≤0.05% / ℃.
