How many thermistors can be placed inside an armored thermistor?
Thread Content
:) To design a small experimental tower, 36 temperature measurement points are required. If armored thermoresistors are to be used, how many temperature measurement points can be covered by one armored thermoresistor?
Generally, it’s between 3 and 8; it depends mainly on how your 36-point layout is arranged to determine how many multi-point thermistors are needed.
Thank you~~~~~ There are 9 temperature measurement points per plane~:) It seems that two points per plane are sufficient. Which manufacturer produces better armored thermoresistors?
Could the original poster explain what an armored platinum resistor is? "What does it mean by \"How many temperature measurement points can be connected to one armored thermistor?\" This post was last edited by s1j2 on 2009-3-10 12:37.]
The question upstairs is great~ You can search for “armoring” on the forum; there are many explanations available, such as http://bbs.hcbbs.com/viewthread.php?tid=339763&highlight=%EE%F8%D7%B0 and http://bbs.hcbbs.com/viewthread.php?tid=261879&highlight=%EE%F8%D7%B0 :) :) :)
First, determine the locations where the thermal resistances will be placed, and then decide how many measurement points are needed at each location based on the process requirements. It is advisable to contact manufacturers of thermal resistances to see if they can produce ones that meet the specified requirements.
An armored thermoresistor consists of a platinum thermoresistor element, leads, and insulating powder, all enclosed within a thin stainless steel tube; this assembly is then compressed and shaped into a single unit using molds. It features durability, vibration resistance, a long service life, bendability, and low measurement lag.
According to the manufacturer’s manual, armored thermoresistors are usually available in pairs; if more are needed, a special order is required.
I asked a company in Shanghai today – they can provide multiple thermal resistors, up to 10 points in total: lol
Upstairs, please explain how it’s possible to have 10 points with multiple thermal resistors.
The multi-point thermometers you mentioned are quite troublesome to use; it’s likely that even Tiankang, the largest temperature measurement equipment manufacturer in China, might not be able to produce them well. I suggest looking for foreign brands – it seems that the multi-point thermometers made by the German company E+H can have 40 measurement points, according to what I’ve heard...
I am from Anhui Tiankang (Group) Co., Ltd. I’m not sure exactly how many points you need! I can have the technical center show it to you! Feel free to contact me if you have any questions! anhuitk@126.com
I just found out that there are also multi-point thermistors; I’ve been using only single-point ones all this time. Thank you to the original poster for the question.
36 points – it’s not possible to achieve this in China, as the requirements aren’t met
I’ve only seen ones with two branches; if there are so many of them, and the armor gets broken due to high temperatures or mechanical damage, then it’s all over
