High precision temperature transmitter is 24 v power supply, the integration of two wire transducer.
Products using imported IC, thermal resistance and thermocouple signal amplification, translates into 4 -
Ma, or 0 to 20
The output current of 10 ma, or 0 ~ 5 v output voltage.
One armoured transmitter can directly measure the temperature of the gas or liquid is particularly suited to low temperature range measurement, overcome the condensed water on the effects of temperature measurement.
Temperature transmitter power supply can not have rush, otherwise easy to damage the transmitter.
Transducer calibration should be performed after power up 5 minutes, and pay attention to the environmental temperature.
When measuring high temperature (>>
Application of filling material isolation between sensors cavity and junction box, prevent the junction box temperature transmitter burn out.
Interference in severe cases using sensors, shell should be solid grounding to avoid interference.
Power supply and signal output should use Ф 10 shielded cable transmission, line pressing nut should tighten in order to ensure the tightness.
Only RWB type of 0 ~ 10 ma output, as the three wire system, in the range value of less than 5%, due to the cut-off characteristic of the triode is not linear.
The transmitter should be calibrated once every six months.
DWB due to restricted by circuit cannot be linear correction, * good choice range according to the instructions in order to ensure its linear.
