Overview
The SBWR-230 thermocouple with temperature transmitter is usually used in conjunction with display instruments, recording instruments, electronic computers, etc., with an output of 4-20mA. It directly measures the temperature of liquid, vapor, gas media, and solid surfaces within the range of -200 ℃ to 1300 ℃ in the presence of explosives such as carbon and chlorine compounds in the production site.
Product Details
SBWR-230 with temperature transmitter thermocoupleUsually with display instruments 、 Recording instrument 、 Used for supporting electronic computers, etc , output 4~20mA.Directly measuring the presence of explosives such as carbon and chlorine compounds on the production site -200 ℃ ~ 1300℃ Liquid within the range, Steam and gas media, as well as solid surface temperature .
SBWR-230 with temperature transmitter thermocoupleWorking Principle:
Explosion proof thermocouple utilizes gap explosion-proof principle,When an explosion occurs inside the cavity,Can extinguish and cool through the gap between the mating surfaces,Make the entire temperature of the explosion flame unable to be transmitted outside the chamber,Thus achieving explosion prevention.
thermocouple(thermal resistor)Generated thermoelectric potential(resistance)Unbalanced signal generated by the bridge of the temperature transmitter,After amplification, it is converted into4~20mAThe DC electrical signal is sent to the working instrument,The working instrument displays the corresponding temperatureValue.
Features:
1. Two line output4~20mA ,Strong anti-interference ability ；
2. Save compensation wire and installation cost of temperature converter ；
3. safe and reliable ， long service life ：
4. Automatic compensation for cold end temperature ， Nonlinear correction circuit ；
