商品說明

Grove – 1-Wire Thermocouple Amplifier (MAX31850K) 1線熱電偶放大器(MAX31850K)

Grove – 1-Wire熱電偶放大器(MAX31850K)是一款熱電偶至數字轉換器,具有14位分辨率和冷端補償。該模塊設計用於與k型熱電偶配合使用。熱電偶的測量範圍比熱敏電阻大得多。例如,我們網站上的這款k型熱電偶的測量範圍為-50℃至+ 600℃。

該模塊基於MAX31850K,集成了放大器,ADC和64位ROM。由於64位ROM,每個器件都有一個獨特的64位串行代碼,允許多個單元在同一條1-Wire總線上運行。因此,使用一個微控制器(主設備)來監控分佈在大面積上的許多熱電偶的溫度是很簡單的。

這個模塊不能單獨工作,必須搭配k型熱電偶(選購)。

注意:

通常K型熱電偶的正極為紅色,負極為淺白色,但我們無法保證所有K型熱電偶都是這樣的。因此上圖僅適用於從我們網站購買的K型熱電偶。如果從其他地方獲得K型熱電偶,則需要使用其他方法來判斷正負極。

=========================================================

 

Grove – 1-Wire Thermocouple Amplifier (MAX31850K)

The Grove – 1-Wire Thermocouple Amplifier (MAX31850K) is a thermocouple-to-digital converters with 14-bit resolution and cold-junction compensation. This module is designed to be used in conjunction with a k-type thermocouple. The thermocouples have a much larger measurement range than thermistors. For example, this k-type thermocouple on our website has a measurement range of -50℃ to +600℃.

This module is based on the MAX31850K, which integrates amplifier, ADC and 64-bit ROM. Thanks to the 64-bit ROM, each device has a unique 64-bit serial code, which allows multiple units to function on the same 1-Wire bus. Therefore, it is simple to use one microcontroller (the master device) to monitor temperature from many thermocouples distributed over a large area.

Again, this module can’t work alone, it must work with a k-type thermocouple, if you do not have one, you can consider Thermocouple Temperature Sensor K Type-1M in our bazaar.

Features

– Integrated Cold-Junction Compensation

– Wide Conversion Range: allow readings from -270℃ to +1768℃

– 14-Bit, 0.25℃ Resolution

– Will not work with any other kind of thermocouple except K type

– Detects Thermocouple Shorts to GND or VDD

– Detects Open Thermocouple

Typical Applications

– Medical

– Appliances

– Industrial

– HVAC(Heating, Ventilation and Air Conditioning)

 

Attention:

Usually the positive pole of the K-type thermocouple is red and the negative is light white, but we can’t guarantee that all K-type thermocouples are like this. So the above diagram is only for the K-type thermocouple purchased from our website. If your K-type thermocouple is obtained from other places, you need to use other methods to judge the positive and negative.
