温度变送器模块为24V供电、二线制的一体化变送器。 DX-SBW series temperature transmitter module is a 24V power supply, two-wire integrated transmitter. The product uses imported integrated circuits to amplify the signal of the thermal resistance or thermocouple and convert it into an output current of 4-20mA or 0-10mA, or an output voltage of 0 ~ 5V. The armored transmitter can directly measure the temperature of gas or liquid, which is especially suitable for low temperature range measurement, which overcomes the influence of condensed water on temperature measurement.
DX-SBW series temperature transmitter module has the following characteristics: can be directly installed in the sensor junction box, the signal is accurate, can be transmitted remotely (maximum 1000M), high accuracy, anti-interference, long-term stability, maintenance-free. This series of products has been widely used in various fields of industrial control.

的供电电源不得有尖峰，否则容易损坏变送器。 The power supply of DX-SBW series temperature transmitter module must not have spikes, otherwise the transmitter will be easily damaged. The calibration of the transmitter should be performed 5 minutes after power up, and pay attention to the ambient temperature at that time. When measuring high temperature (>> 100 ℃), the filling between the sensor cavity and the junction box should be isolated to prevent the junction box from overheating and burning the transmitter. When the sensor is used under severe interference, the case should be firmly grounded to avoid interference. The signal output should be transmitted by Ф10 shielded cable, and the crimping nut should be tightened to ensure air tightness. Only RWB type has 0 ~ 10mA output, which is a three-wire system. Below 5% of the range value, non-linearity is caused due to the shutdown characteristics of the transistor. The transmitter should be calibrated every 6 months. DWB cannot be linearized due to circuit limitations For correction, it is best to select the range according to the instructions to ensure its linearity. zzyfwh.com
