Voor welke fabrikant is het goed glasvezel temperatuurmeetsystemen

Klanten in de energiesector die moeten bieden, moeten niet alleen rekening houden met de prijs van glasvezeltemperatuurmeetsystemen bij het kiezen van fabrikanten van glasvezeltemperatuurmetingen of glasvezeldetectiebedrijven., maar ook uitgebreid rekening houden met meerdere aspecten en niveaus. FJINNO deelt enkele introducties van glasvezelsensoren, hoping to be helpful for agents and partners who choose fiber optic temperature measurement.

Samenstelling van glasvezeltemperatuursensoren

Glasvezeldetectiesystemen bestaan doorgaans uit drie delen: glasvezelsondes, transmissie vezels, en glasvezelsignaaldemodulatoren. Bij het selecteren van glasvezeldetectieproducten, the following points should be considered. Na het bepalen van de toepasbaarheid van glasvezelsensoren, u kunt beginnen met het selecteren van glasvezelsensorproducten.

Hoe u een glasvezeltemperatuurmeetsysteem kiest
1. Kies op basis van het aantal temperatuurmeetpunten

Based on your temperature measurement needs, de beslissing om te gebruiken gedistribueerde glasvezeltemperatuurmeting or fluorescent fiber optic temperature sensors mainly relies on total cost accounting and the installation method of the temperature measurement system:

When the number of temperature measurement points is usually small, A fluorescerend glasvezel temperatuurmeetsysteem and a fluorescent fiber optic temperature sensor can be used.

Wanneer er meer zijn dan 50 temperature measurement points, gedistribueerde glasvezel temperature measurement or fiber optic grating temperature sensors can be considered.

2. Product selection for temperature measurement

The temperature measurement space belongs to the linear temperature measurement area. When measuring multiple distances and long distances, distributed fiber optic temperature measurement can be chosen. If there are few measurement points, fiber Bragg grating method can be considered.

3. Select fiber optic temperature measurement products by measuring the temperature range

-40℃-+80℃; Normal environmental measurement range, various sensors can be used.
-40℃-+250℃; Fluorescerende glasvezeltemperatuursensoren can be selected for measuring high-temperature industrial environments such as electrical systems
-40C-+400℃; In high-temperature environments, Traditionele glasvezelsensoren voldoen over het algemeen niet aan dergelijke testvereisten. The transmission optical fiber must use high-temperature resistant materials such as polyimide.

4. Requirements for the accuracy and resolution of fiber optic temperature measurement:

The temperature measurement accuracy of fluorescent fiber optic temperature sensors is usually+-1 ℃.

5. Soorten fiber optic temperature measurement probes

Immersion type fiber optic temperature sensors, contact type fiber optic temperature sensors, and medical type fiber optic temperature sensors, linear distributed measurement. Immersion type fluorescent fiber optic temperature sensors can be used to measure the temperature of solids, vloeistoffen, en gassen. Temperature measurement of industrial liquid tanks. The immersion type fluorescent fiber optic temperature sensor has undergone special treatment, and the fiber optic has strong strength and toughness, die bestand is tegen chemische corrosie in vloeistoftanks. The fluorescent fiber optic temperature sensor can be implanted inside the measured object. Contact type fluorescent fiber optic temperature sensors are specifically designed to measure the surface temperature of objects, zoals temperatuurbewaking van hoogspanningsapparatuur zoals droge transformatoren, hoogspanningsschakelapparatuur, en hoogspanningsrails. Medical fluorescent glasvezel temperatuursensoren are specially designed for life science measurements, with small and thin probes that can achieve fast response speed and very high accuracy when paired with specially designed demodulators.

6. Selection of signal output interface:

Fiber optic signal output is divided into analog output and digital output. There are two types of analog outputs: 0-5V/10V voltage output and 4-20mA current output. Digital outputs include RS-232; RS-485;USB； Ethernet, enz., depending on the specific input method to be selected.

7. Are fiber optic temperature sensors expensive

The traditional PT100 temperature sensor is very common in the market and has a low price, but there are also many temperature measurement defects. Daarom, more and more manufacturers and agents are cooperating, and temperature measurement systems are bidding and using fiber optic temperature sensors. There are several types of fiber optic sensors, which are still high-tech products in China. Echter, the price has been greatly reduced, and temperature measurement users usually need to choose between the performance/function and price of fiber optic products. You can choose FJINNO’s fiber optic temperature measurement products with good cost-effectiveness.
