Overview

The SBW series temperature transmitter module is a 24V powered, two-wire integrated transmitter. The temperature transmitter product adopts imported integrated circuits to amplify the signal of the thermistor or thermocouple and convert it into 4-20mA or 0-10mA output current, or 0-5V output voltage. The armored transmitter can directly measure the temperature of gases or liquids, and is particularly suitable for low-temperature range measurement, overcoming the influence of condensed water on temperature measurement

Product Details

Characteristics of SBW series temperature transmitter
The ZN-SBW series temperature transmitter module has the following characteristics: can be directly installed in the sensor junction box, accurate signal, remote transmission (up to 1000M), high accuracy, anti-interference, good long-term stability, and maintenance free. This series of products has been widely used in various fields of industrial control.

Precautions for temperature transmitter
The power supply of the module must not have spikes, otherwise it is easy to damage the transmitter. The calibration of the transmitter should be carried out 5 minutes after power on, and attention should be paid to the ambient temperature at that time. When measuring high temperatures (>>100 ℃) with a temperature transmitter, the sensor chamber and junction box should be isolated with filling materials to prevent the junction box from overheating and burning out the transmitter When using sensors with severe interference, the housing should be firmly grounded to avoid interference The power and signal output should be transmitted using a shielded cable with a diameter of 10, and the crimping nut should be tightened to ensure airtightness. Only the RWB type temperature transmitter has a 0-10mA output, which is a three wire system. When the range value is below 5%, the nonlinearity is caused by the turn off characteristic of the transistor The transmitter should be calibrated every 6 months DWB cannot perform linear correction due to circuit limitations. Select the range according to the instructions to ensure its linearity.
