Precautions for temperature transmitters

The power supply of the temperature transmitter 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 ℃), filling materials should be used to isolate the sensor chamber from the junction box to prevent the transmitter from being burnt out due to high temperature in the junction box. When using sensors in situations of severe interference, the casing should be firmly grounded to avoid interference, and the power and signal output should use Ф 10 shielded cable transmission, the crimping nut should be tightened to ensure airtightness. Only the RWB temperature transmitter has a 0-10mA output, which is a three wire system and is below 5% of the range value. Due to the off characteristic of the transistor, it is not linear. Temperature transmitters should be calibrated every 6 months. If DWB cannot perform linear correction due to circuit limitations, it is best to select the range according to the instructions to ensure its linearity.
