PRODUCT OF TEMPERATURE INSTRUMENT

 

SBW TEMPERATURE TRANSMITTER

SBW temperature transmitter is the new generation of intelligent field bus transmitter, can support HART  Protocol. SBW  transmitter integrates thermocouple/RTD and temperature transmitter module which can realize not only normal measurement function but also complicated control function.

SBW temperature transmitter can broaden the measure range and provide easier connection between field and control room, and reduce  the  expense  on  deployment  and maintenance,  now   it have  been broadly  used  in  chemical industry,metallurgy  and oil  field, etc.

BIMETALLIC THERMOMETER

Summarize

Bimetallic thermometer is used for field testing of low or middle temperature ( from -80℃ to 500℃), Can directly measure the temperature of all kinds of liquid, steam and gas medium.

Features

1. Local indication

2. Safe, reliable, and long service life

3. Multiple structure form, can meet different demands

Principle

Bimetallic thermometer’ temperature element is made of bimetallic strip which is bent into a coil, one end will expand when it is heated, meanwhile drive the pointer rotate, which will show the corresponding temperature of medium.

 

Main technical Specification
