Product Description

4.7K Ntc Thermisters Epoxy bead temperature probe
 

Product Description

4.7K Ntc Thermisters epoxy bead temperature probe is made of NTC chip, epoxy and CP lead wire or transparent sleeve by soldering them together and coating soldered part by epoxy.  NTC Thermistor sensor is used in general purpose temperature measurement solutions for residential, industrial, and commercial applications. The thermistor element is epoxy into the stainless steel probe that is quite sensitive and response quickly to changes in the temperature. The sensor element used is a 4.7K Thermistor and can be used with many popular brands of RT manufacturers.

FAQ

Q: What isThermal Time Constant?
A: Thermal Time Constant simply put, under zero conditions, is the time it takes a thermistor temperature sensor to change 63.2% of the total difference between the initial and the final body temperature; when subjected to a step function change in temperature. In simple terms, it represents in time, how long it takes a thermistor to recover up to 50% of its initial resistance.

Q: When to use NTC Thermistor Probes and why it's necessary?
A: NTC Thermistor probes have been used as far back as 1940 to measure and analyze temperature, but today they are indispensable to everything from home appliances to electric vehicles that require li-ion batteries. They have long been employed to measure liquid levels and temperature in industries that extend from automotive electronics to medical technology to green energy. Their applications are endless, and their purpose is significant.
NTC thermistor temperature sensors come in all types of housings including closed end metal tubing, threaded metal tubing, and housings with a threaded tip and hex screw.
A thermistor probe is otherwise identified as a bead thermistor manufactured as a bare bead encapsulated with epoxy or glass that is usually potted in a metal or plastic housing with two high temperature insulated wires.

Q: How to select and integrate thermistor probes into different applications?
A: Like the limitless applications requiring thermistor probes, so too exist the endless methods to mount them, adhere them and apply them. Some thermistors can get very sophisticated in the ways that they are housed and the methods in which they are mounted.
