◆ Application
     The transmitters can be assembled in terminal box of the thermocouple or RTD and get intergrated structure. They work as a new generation temperature measuring instruments are widely used in metallurgy, petroleum, chemical, power, light industry, textile, food, national defense and scientific research industry.

◆ Features
     The transmitters adopt silicon rubber or epoxy resin sealed structure, is vibration-proof and moisture-proof, suitable for use in harsh field environment.
     The transmitter can be assembled in terminal box of the thermocouple or RTD and export 4-20mA or 0-10mA directly, which not only saves the expensive cost of the compensation wire, and also improves the anti-interference performance in long-distance transmission;
     The thermocouple transmitters have function of cold-junction temperature automatic compesation. 
     High accuracy, low power consumption, wide operating temperature range, stable and reliable; 
     Wide application: 1. integrated with thermocouple and RTD, 2. installed in inspection equipment or instruments' panel as an independent module directly; 
     Smart HART temperature transmitter can communicate with PC or handle operator; transmitter's model, type and measuring range can be remotely managed, configued, monitoring, calibrated and maintained.
     Smart temperature transmitters can display temperature, change of the transmitter's value, output current and percentage, and the display direction of it can be adjusted as needs;
