I Company Introduction                                     

Yantai dongrun Instrument Co., Ltd. was founded in 1998, specializes in manufacturing online water quality analysis equipment, material level meters, pressure gauges, flow meters, special temperature gauges and laboratory analysis equipment. Our company cooperate with the Chinese Academy of Sciences to build a water analysis laboratory, and the main products are TOC analyzer, ammonia analyzer, fluorescence oxygen analyzer, etc. We have passed the ISO9001 certification and has a professional R & D team, providing technical support to meet customer demand, particularly in the anti-corrosion, our company has a unique technology to meet different conditions of corrosion requirements.

Product Introduction

Application: 

Usually, with display instruments, recording instruments, computer and other ancillary uses, output 4 ~ 20mA, 

Direct measurement of the production process in the range of 0 ~ 1600 ℃ of liquid, vapor, gas and solid surface 

temperature.

Features:

1. The two-wire output 4 ~ 20mA, strong anti-jamming capability

2. saving temperature transmitter compensation wire and installation costs

3. Wide Measuring range

4. The automatic cold junction temperature compensation, nonlinear correction circuit

Working principle

Thermocouple (RTD) in working condition measured thermoelectric power (resistance) changes, 

after the bridge of temperature transmitter generate unbalanced signal, After amplification converted

 into 4 ~ 20mA DC signal to the working instrument, working instrument will show the corresponding

 temperature value. 

The main technical parameters

Output signal: 4 ~ 20mA, load resistance 250Ω, 100Ω transmission line resistance

Output method: Two-wire

Tolerance Level: 0.1,0.2,0.5

Power supply: 24VDC ± 10%
