temperature data acquisition

Introduction

1.Specification

STC-106 is a Remote Terminal Unit for control and date acquisiton.It was Widely used in monitoring system or computer room where had many thermal resistance. STC-106 adopted our unique bridge circuit measurements technology.no temperature drift, no influence of lead resistance, stronger anti-interference.

The bridge circuit is isolate from measurement circuit completely. STC-106 have many other advantages.

4.Thermal Resistance

PT-100 is normally used in RTD(-200°C~650°C), its a temperature sensing element,basically called as platinum 100, for positive temperature co-efficient.if temperature increases resistance also increases, the increase of resistance is due to the applide voltage passing through the sensing element, it has resistance,for 0 degree celcius 100 ohms.The principle of operation is to measure the resistance of a platinum element. The most common type (PT100) has a resistance of 100 ohms at 0°C and 138.5 ohms at 100 °C. There are also PT1000 sensors that have a resistance of 1000 ohms at 0 °C.

The relationship between temperature and resistance is approximately linear over a small 

 temperature range: for example, if you assume that it is linear over the 0 to 100 °C range, the error at 50 °C

 is 0.4 °C. For precision measurement, it is necessary to linearise the resistance to give an accurate

 temperature. The most recent definition of the relationship between resistance and temperature is

 International Temperature Standard 90 (ITS-90). For a PT100 sensor, a 1°C temperature change will cause

 a 0.385 ohm change in resistance.
