Integrated intelligent flame-proof type temperature transmitter

     
SBW series integrated explosion-proof temperature transmitter
 

 
 
Product number
HX-RS-SBW4480
Product name
Integrated intelligent flame-proof type temperature transmitter
Product description
The temperature measuring probe of the integrated intelligent flameproof temperature transmitter is composed of three parts: an explosion-proof junction box, a process connection and a temperature measuring protection tube. The flameproof temperature transmitter adopts explosion proof isolation junction box, which can effectively prevent the explosion vibration from damaging the transmitter. It can protect the circuit and avoid the safety of sparks.
Temperature probe integrated intelligent flameproof temperature transmitter with platinum resistance, high precision, good stability; in one set of sensor transmission, compact structure, convenient installation, high precision, low power consumption; current output type is suitable for long distance transmission, anti electromagnetic interference circuit design, to ensure safe and reliable in the transmitter to be subjected to various disturbances suitable for modern work, serious electromagnetic pollution environment;
The overall sealing performance is good, the temperature range and the size of the form can be ordered by the customerFlexible and convenient; products, reasonable structure design, process connection interface flexibility, small size, light weight, installation position of any shell; protection of different materials, to adapt to a variety of media measurement standard pipe thread installation.
