Which manufacturer is good for fiber optic temperature measurement systems

Customers in the power industry who need to bid should not only consider the price of fiber optic temperature measurement systems when choosing fiber optic temperature measurement manufacturers or fiber optic sensing companies, but also comprehensively consider multiple aspects and levels. FJINNO shares some introductions of fiber optic sensors, I håb om at være nyttig for agenter og partnere, der vælger fiberoptisk temperaturmåling.

Composition of fiber optic temperature sensors

Fiber optic sensing systems are usually composed of three parts: Fiberoptiske sonder, transmissionsfibre, and fiber optic signal demodulators. When selecting fiber optic sensing products, Følgende punkter bør overvejes. After determining the applicability of fiber optic sensors, Du kan begynde at vælge fiberoptiske sensorprodukter.

How to choose a fiber optic temperature measurement system
1. Choose based on the number of temperature measurement points

Baseret på dine behov for temperaturmåling, the decision to use Distribueret fiberoptisk temperaturmåling or fluorescent fiber optic temperature sensors mainly relies on total cost accounting and the installation method of the temperature measurement system:

Når antallet af temperaturmålepunkter normalt er lille, a fluorescent fiber optic temperature measurement system and a fluorescent fiber optic temperature sensor can be used.

Når der er mere end 50 Målepunkter for temperatur, distribueret fiberoptisk temperaturmåling eller fiberoptiske gittertemperatursensorer kan overvejes.

2. Produktvalg til temperaturmåling

Temperaturmålingsrummet hører til det lineære temperaturmåleområde. When measuring multiple distances and long distances, distributed fiber optic temperature measurement can be chosen. Hvis der er få målepunkter, fiber Bragg gittermetode kan overvejes.

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

-40°C-+80°C; Normal environmental measurement range, various sensors can be used.
-40°C-+250°C; Fluorescent fiber optic temperature sensors can be selected for measuring high-temperature industrial environments such as electrical systems
-40C-+400°C; I miljøer med høje temperaturer, Traditionelle fiberoptiske sensorer opfylder generelt ikke sådanne testkrav. 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:

Temperaturmålingsnøjagtigheden for fluorescerende fiberoptiske temperatursensorer er normalt +-1 °C.

5. Types of 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. Fluorescerende fiberoptiske temperatursensorer af nedsænkningstypen kan bruges til at måle temperaturen på faste stoffer, Væsker, og gasser. Temperaturmåling af industrielle væsketanke. The immersion type fluorescent fiber optic temperature sensor has undergone special treatment, and the fiber optic has strong strength and toughness, som kan modstå kemisk korrosion i væsketanke. 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, såsom temperaturovervågning af højspændingsudstyr såsom tørtransformere, højspændingskoblingsudstyr, og højspændingsskinner. Medical fluorescent fiber optic temperature sensors 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. Valg af signaludgangsgrænseflade:

Fiberoptisk signaludgang er opdelt i analog udgang og digital udgang. 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, osv., 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. Derfor, more and more manufacturers and agents are cooperating, and temperature measurement systems are bidding and using fiber optic temperature sensors. Der findes flere typer fiberoptiske sensorer, som stadig er højteknologiske produkter i Kina. Dog, 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.
