Product introduction

First, an overview:

Temperature transmitter module SBWR, SBWZ series thermocouple, Thermal resistance Temperature field transmitter is DDZ series instrument-mounted temperature transmitter unit, with industrial thermocouple, RTD used, it uses a two-wire transmission mode (two wires for power input and signal output of public transport lines). Industrial thermocouple, RTD signal into the input signal or linear with temperature signal 4-20mA, 0-10mA output signal.

Temperature transmitters Module Can be mounted directly on the thermocouple and thermal resistance of the junction box and the formation of integration structures. As a new generation of instruments can be widely used in metallurgy, petroleum, chemical industry, electric power, light industry, textile, food, defense, scientific research and other industrial sectors.

Two main features:

Temperature transmitter module structure of Silicon rubber or epoxy resin sealing, vibration-proof, resistant to Chao Wet, suitable for use in harsh field environments installed.

Thermocouple temperature transmitter module installed and used within the thermal resistance of the junction box, direct output 4-20mA, 0-10mA output signal. This will not only save the expensive costs of compensating cables, and increases the signal long-distance transmission interference;

Module thermocouple temperature transmitter transmitter with automatic cold junction temperature compensation function;

High precision of temperature transmitter module, low power consumption, wide operating temperature range, stable and reliable;

Transmitter module applicable to a wide range of temperature, thermocouple, RTD to form integrated installation structure, or as a function module in the testing equipment and used on the dashboard;

Intelligent temperature transmitter module through a HART modem and PC communications or with the handset and PC model of transmitter, indexing, range for remote management, configuration, variables monitoring, calibration and maintenance functions;

Intelligent temperature transmitter module according to user actual need to adjust the transmitter display Numerical And displays the temperature measured by the transmitter, sensor values change, the output current and percentage;

Third, the principle of work:

Temperature transmitter module, thermocouple or RTD sensor converts the measured temperature into an electrical signal, and the signal sent to the transmitter Processing circuit , Processing circuit Contains zero adjustment and compensation circuit. The zero signal input to the op-amp signal amplification, amplifier signal is v/I converter to process all the way to 4-20mA direct current output; Another by the a/d converter to the table header. Transmitter linear circuit there are two, use feedback form. Thermal resistance sensor, with positive feedback correction for thermocouple sensors, calibration with a polyline approximation. Integrated digital display of temperature transmitter there are two display modes. Two-wire output Or Three-wire output.

Four, Main Technical parameters:

1, the input signals: thermocouples: k, e, j, b, s, t, n. RTD: Pt100, Cu50

Cu100 (three-wire, four-wire system). Intelligent temperature transmitter input signal through the handset and PC set;

2, the output signal: output 4-20mA DC signal in the range, with the thermocouple or RTD input signals into a linear or linear with temperature. Intelligent temperature transmitter 4-20mA DC output signal and superimposed with HART protocol communication; Isolated temperature transmitter: the input and output are isolated, isolation voltage 500V, increased resistance to common-mode interference, more suitable for computer Alliance Network use;

3, error: 0.5%FS 0.25%FS, smart-0.2%FS;

4, connection: two-wire and three-wire, four-wire;

5, display: four-digit LCD display temperature ; Intelligent four-digit LCD to PC machine or hand set displays the field temperature, sensor values, output current and the percentage in the case of a parameter;

6, operating voltage: 12V-32V, rated working voltage of 24V

7, allowing load resistance: 500 ω (24VDC power supply); Limit the load resistor r (max) =50 (Vmin-12), for example at rated operating voltage 24V, the load resistor can be used 0-600 ω range.
